Loading Transfer Ribbon
Transfer ribbons come in several varieties and in some cases colors to match your application
needs. Zebra brand transfer ribbons are specifically designed for your printer and Zebra brand
media. Using non-Zebra brand or media or ribbon not approved for use in your Zebra printer
may damage your printer or printhead.
• The media and ribbon types should be matched to provide you with optimal print results.
• Always use ribbon that is wider than the media to protect the printhead from wear.
• For direct thermal printing, do not load ribbon in the printer.
Your printer needs to use Zebra Uni-Ribbons (universal ribbon). Uni-Ribbons have a ribbon
out trailer (reflector) to stop printing when empty. Zebra Uni-Ribbons will work on older
model Zebra desktop printers too.
Uni-Ribbons are identified with a color coded leader.

Serial Communications
The required cable must have a nine-pin “D” type (DB-9P) male connector on one end, which
is plugged into the mating (DB-9S) serial port located on the back of the printer. The other end
of this signal interface cable connects to a serial port at the host computer. Depending on the
specific interface requirements, this will most likely be a Null Modem (cross-over) cable.
Early models of Zebra printers running the EPL programming typically utilized a straight
through signal connections cable (no cross-over). For pinout information, refer to Appendix A.
Note • The printer design does not allow for the use non-molded cables such as hand-made
cables with large clam shell connector covers.
The serial port communication settings between the printer and host (typically a PC) must
match for reliable communication. The Bits per second (or Baud rate) and Flow control are the
most common settings that get changed. The hosts (typically a Windows PC) needs to have the
data Flow control changed to match the printer’s default communication method: Hardware
and is noted by the Host Handshake setting DTR/Xon/Xoff. This combined hardware
(DTR) and software (Xon/Xoff) mode may need to change depending upon the non-Zebra
application software and the serial cable variation in use.
Serial communications between the printer and the host computer can be set by:
•
•
•
•
Autobaud synchronization
ZPL programming ^SC command
EPL programming Y command
Resetting the printer to its default printer configuration.
Autobaud
Autobaud synchronization allows the printer to automatically match the communication
parameters of the host computer. To autobaud:
1. Press and hold the feed button until the green status LED flashes once, twice, and then
three times.
2. While the status LED flashes, send the ^XA^XZ command sequence to the printer.
3. When the printer and host are synchronized, the LED changes to solid green. (No labels
will print during autobaud synchronization.)
ZPL ^SC Command
Use the Set Communications (^SC) command to change the communications settings on the
printer.
1. With the host computer set at the same communications settings as the printer, send the
^SC command to change the printer to the desired settings.
2. Change the host computer settings to match the new printer settings.
Refer to the ZPL Programming Guide for more information about this command.

Use the serial port setup (Y) command to change the communications settings on the printer.
1. With the host computer set at the same communications settings as the printer, send the
Y command to change the printer to the desired settings. Note: the Y command does not
support setting the data flow control, use the Xon/Xoff setting.
2. Change the host computer settings to match the new printer settings.
Refer to the EPL Page Mode Programming Guide for more information about this command.
Resetting the Default Serial Port Parameters
Do the following to reset the communications parameters on the printer to the factory defaults
(serial communication settings are: 9600 baud, 8 bit word length, NO parity, 1 stop bit, and
DTR/XON/XOFF data flow control).
1. Press and hold the feed button until the green status LED flashes once, waits a moment
and flashes twice, and then waits again before flashing three times (release immediately).
2. While the status LED rapidly flashes amber and green, press the feed button. Serial
communications between the printer and the host computer can be set by the ZPL ^SC
command or the EPL Y command.
Note • Early models of Zebra printers running the EPL programming language had 9600
baud, NO parity, 8 data bits, 1 stop bit and a HARDWARE and SOFTWARE (merged) data
control (essentially DTR/Xon/Xoff) as the default serial port settings. The Windows operating
system flow control setting was Hardware for most applications.

Communicating with the Printer
Begin installing the Zebra Windows Driver and then turn on the printer. If the operating
system automatically starts a ‘Add new hardware’ wizard, then close the wizard and continue
installing the driver.
Universal Serial Bus (USB) Communications
The printer is a terminal device when using a universal serial bus interface. You can refer to
the Universal Serial Bus Specification for details regarding this interface. Scanners, scales or
other data input devices must use the serial port to send data to the printer.
USB and Parallel Port Printer Detection and Windows® operating systems
Windows Vista, Windows XP, Windows 2000 and Windows 98 Second Edition (USB only)
operating systems support the USB and bidirectional parallel port communications with
printers. The Zebra Windows Driver supports your printer in these operating systems.
These operating systems automatically detect the printer when connected via the USB
interface. The operating system automatically starts a “Add new hardware’ wizard when
connecting the printer for the first time to the PC. Close the wizard. Install the Zebra Windows
parallel port and then media size (closest match). Click on the ‘Print test page’ button to verify
a successful installation.
The Windows operating system will detect and re-link a previously installed printer if it is
reconnected to the USB interface or power is turned on after the PC has finished its restart of
the operating system. Ignore the new device detected warnings and close the Task bar prompts.
Wait several seconds for the operating system to match the printer to the driver software. The
warnings will quit and the printer now should be ready to begin printing.
Serial Port and Windows® operating systems
The Windows operating system default settings for the serial port communication closely
match the printer’s defaults settings with one exception; the data Flow Control settings. The
Windows default data Flow Control setting is NONE. The G-Series printer requires data Flow
Control set to Hardware.
Note • The G-Series printer does not support Windows Serial Port Plug and Play (PnP)
device detection at this time.

Determining Printer Configuration
The G-Series printer uses a ZPL printer configuration status label to report the printer’s
configuration status for both EPL and ZPL operations.The ZPL style label provides a more
intuitive and functionally descriptive naming conventions than the EPL style printer status
label. Operational status (darkness, speed, media type, etc.), installed printer options (network,
interface settings, cutter, etc.) and printer description information (serial number, model name,
firmware version, etc.) are all includes on the status label.
To get an EPL style printer configuration status label, send the printer the EPL U command.
See the EPL programmer’s guide for more information on the various EPL U commands and
interpreting the settings displayed on these labels.
The printer configuration status label can be localized for up to 16 languages. Use the ZPL
programming command ^KD to modify the displayed language for most status items on this
label.
on page 89 for information on accessing the printer configuration status label.
Thermal Printing
Caution • The printhead becomes hot while printing. To protect from damaging the
printhead and risk of personal injury, avoid touching the printhead. Only use the cleaning
pen to perform printhead maintenance.
Caution • The discharge of electrostatic energy that accumulates on the surface of the
human body or other surfaces can damage or destroy the printhead or electronic
components used in this device. You must observe static-safe procedures when working
with the printhead or the electronic components under the top cover.

after it is printed.
• Label Dispense Mode: If an optional dispenser is installed, the backing material can be
peeled away from the label as it is printed. After this label is removed, the next one is
printed.
• Media Cutting: If an optional media cutter is installed, the printer can cut the label liner
between labels, receipt paper or tag stock depending upon the cutter option purchased.
• Stand-alone: The printer can run in a stand-alone mode (not connected to a computer)
using the printer’s auto running label form feature (programming based) or by using an
data input device. This mode accommodates data input devices, such as scanners, weigh
scales, Zebra KDU Plus or KDU (Keyboard Display Unit) with a KDU Adapter, etc., via
the printer’s serial port.
• Shared network printing: Printers configured with the Ethernet interface option include an
internal print server with ZebraLink printer configuration web page and ZebraNet Bridge
software for managing and monitoring status of Zebra printers on a network.
Print Media Types
Important • Zebra strongly recommends the use of Zebra-brand supplies for continuous
high-quality printing. A wide range of paper, polypropylene, polyester, and vinyl stock has
been specifically engineered to enhance the printing capabilities of the printer and to prevent
Your printer can use various types of media:
• Standard media—Most standard (non-continuous) media uses an adhesive backing that
sticks individual labels or a continuous length of labels to a liner.
• Continuous roll media—Most continuous roll media is direct thermal media (similar to
FAX paper) and is used for receipt or ticket style printing.
• Tag stock—Tags are usually made from a heavy paper (up to 0.0075in./0.19mm thick).
Tag stock does not have adhesive or a liner, and it is typically perforated between tags.
The printer typically uses roll media, but you can use fan-fold or other continuous media too.
Use the correct media for the type of printing you require. When printing without a ribbon, you
must use direct thermal media. When using ribbon, you must use thermal transfer media.

How It Looks
Description
Non-Continuous
Roll Media
Roll media is wound on a core that can be 1 in. to 3 in. (25 to
76 mm) in diameter. Labels have adhesive backing that sticks
them to a liner, and they are separated by gaps, holes, notches,
or black marks. Tags are separated by perforations. Individual
labels are separated by one or more of the following methods:
• Web media separates labels by gaps, holes, or notches.
• Black mark media uses pre-printed black marks on the back
side of the media to indicate label separations.
• Perforated media has perforations that allow the labels or
tags to be separated from each other easily. The media may
also have black marks or other separations between labels
or tags.
Non-Continuous
Fanfold Media
Fanfold media is folded in a zigzag pattern. Fanfold media can
have the same label separations as non-continuous roll media.
The separations would fall on or near the folds.
Continuous
Roll Media
Roll media is wound on a core that can be 1 in. to 3 in. (25 to
76 mm) in diameter. Continuous roll media does not have
gaps, holes, notches, or black marks to indicate label
separations. This allows the image to be printed anywhere on
the label. Sometimes a cutter is used to cut apart individual
labels. With continuous media, use the transmissive (gap)
sensor so the printer can detect when the media runs out.

Determining Thermal Media Types
Thermal transfer media requires ribbon for printing while direct thermal media does not.
To determine if ribbon must be used with a particular media, perform a media scratch test.
To perform a media scratch test, complete these steps:
1. Scratch the print surface of the media with a finger nail or pen cap. Press firmly and
quickly while dragging it across the media surface. Direct thermal media is chemically
treated to print (expose) when heat is applied. This test method uses friction heat to expose
the media.
2. Did a black mark appear on the media?
If a black mark...
Then the media is...
Does not appear on the media
Appears on the media
Thermal transfer. A ribbon is required.
Direct thermal. No ribbon is required.
Replacing Supplies
If labels or ribbon run out while printing, leave the printer power on while reloading (data loss
results if you turn off the printer). After you load a new label or ribbon roll, press the Feed
button to restart.
Always use high quality, approved labels, tags and ribbons. If adhesive backed labels are used
that don’t lay flat on the backing liner, the exposed edges may stick to the label guides and
rollers inside the printer, causing the label to peel off from the liner and jam the printer.
Permanent damage to the printhead may result if a non-approved ribbon is used as it may be
wound incorrectly for the printer or contain chemicals corrosive to the printhead.
Adding a New Transfer Ribbon
If ribbon runs out in the middle of a print job, the indicator lights red and the printer waits for
you to add a fresh roll.
1. Keep the power on as you change ribbon.
2. Open the top cover, then cut the used ribbon so you can remove the cores.
3. Load a new ribbon roll. If necessary, review the Ribbon Loading steps.
4. Close the top cover.
5. Press the Feed button to restart printing.

Replacing a Partially Used Transfer Ribbon
To remove used transfer ribbon, perform the following steps.
1. Cut the ribbon from the take-up roll.
2. Remove the take-up roll and discard used ribbon.
3. Remove the supply roll and tape the end of any fresh ribbon to prevent it from
unwrapping. When reinstalling a partially used supply roll, tape the cut end onto the
empty take-up roll.
Adjusting the Print Width
Print width must be set when:
• You are using the printer for the first time.
• There is a change in media width.
Print width may be set by:
• The Windows printer driver or application software such as Zebra Designer.
• Controlling printer operations with ZPL programming; refer to the Print Width (^PW)
command (consult your ZPL Programming Guide).
• Controlling printer operations with EPL Page Mode programming, refer to the Set Label
Width (q) command (consult your EPL Programmer’s Guide).
Adjusting the Print Quality
Print quality is influenced by the heat or density (setting) of the printhead, the print speed, and
the type of media you are using. Only by experimenting will you find the optimal mix for your
application.
Note • Media manufactures may have specific recommendations for speed settings for your
printer and the media. Some media types have lower maximum speeds than your printer’s
maximum speed.
The relative darkness (or density) setting can be controlled by:
and EPL programmed darkness/density settings.
• The Set Darkness (~SD) ZPL command (consult your ZPL Programming Guide).
• The Density (D) EPL command (consult your EPL Programmer’s Guide).
If you find that the print speed needs to be adjusted, use:
• The Windows printer driver or application software such as Zebra Designer.
• The Print Rate (^PR) command (consult your ZPL Programming Guide).
• The Speed Select (S) command (consult your EPL Programmer’s Guide).

Media Sensing
35
Media Sensing
The G-Series printer has automatic media sensing capability. The printer is designed to
continuously check and adjust media length sensing for minor variations. Once the printer is
printing or feeding media, the printer continually checks and adjusts the media sensing to
accommodate for minor changes in media parameters from label to label on a roll and from
roll to roll of media. The printer will automatically initiate a media length calibration if the
expected media length or the label to label gap distance has exceeded the acceptable variation
range when starting a print job or Feeding media. The automatic media sensing in the G-Series
printers works the same for printer operations that use EPL and ZPL label formats and
programming.
If the printer does not detect labels or blacklines (or notches with blackline sensing) after
feeding the media the default maximum label length distance of 39 inches (1 meter), then the
printer will switch to continuous (receipt) media mode. The printer will keep these settings
until changed by software, programming or a manual calibration with different media.
Optionally, the printer can be set to do a short media calibration after printer power up or when
closing the printer with power on. The printer will then feed up to three labels while
calibrating.
The printer’s media settings can be verified by printing a Printer Configuration label. See the
The maximum distance that the automatic media type detection and sensing will check can be
reduced by using the ZPL Maximum Label Length command (^ML). It is recommended that
this distance be set to no less than two times the longest label being printed. If the largest label
being printed was a 4 by 6 inch label, then the maximum label (media) length detection
distance can be reduced from the default distance of 39 inches down to 12 inches.
If the printer has difficulty automatically detecting the media type and auto-calibrating, see
of sensor operation for your media. This method disables the printer’s automatic media
sensing capability until the printer’s default parameters are reset to the factory defaults with
The automatic media calibration can be modified, turned on or turned off to meet your needs.
Sometimes print job conditions require that the printer use all the media on a roll. The two
automatic media conditions, power up with media loaded and closing the printer with power
on, can be controlled individually with the ZPL Media Feed command, ^MF. The feed action
discussed in the ZPL programmers guide for the ^MF command is primarily for automatic
media sensing and calibration. The automatic media calibration that controls the dynamic
media (label to label) calibration is the ^XS command. If multiple media types of different
lengths, material or detection methods (web/gap, blackline or continuous) are used, you should
not change these settings.
The media calibration and detection process can also be refined to match the media type
loaded into the printer. Use the ZPL Media Tracking command (^MN) to set the media type.
Sometimes the printer can detect preprinted media as the gap between labels or the liner
backing with print as a blackline marks. If the ^MN parameter for continuous media is set, then
the print does not preform the automatic calibration. The ^MNcommand also includes an
automatic calibration parameter (^MNA) to return the printer to its default setting to
automatically detect all media types.

Ribbon Overview
36
Ribbon Overview
Ribbon is a thin film that is coated on one side with wax, resin, or wax resin, which is
transferred to the media during the thermal transfer process. The media determines whether
you need to use ribbon and how wide the ribbon must be. When ribbon is used, it must be as
wide as or wider than the media being used. If the ribbon is narrower than the media, areas of
the printhead are unprotected and subject to premature wear.
When to Use Ribbon
Thermal transfer media requires ribbon for printing while direct thermal media does not.
Direct thermal media should never be used with ribbon. Bar codes and graphics can get
distorted. To determine if ribbon must be used with a particular media, perform a media
scratch test.
Coated Side of Ribbon
Ribbon can be wound with the coated side on the inside or outside. This printer can only use
ribbon that is coated on the outside. If you are unsure which side of a particular roll of ribbon
is coated, perform an adhesive test or a ribbon scratch test to determine which side is coated.
Outside
Inside
To determine which side of a ribbon is coated, complete these steps:
Ribbon Test with Adhesive
If you have labels available, perform the adhesive test to determine which side of a ribbon is
coated. This method works well for ribbon that is already installed.
To perform an adhesive test, complete these steps:
1. Peel a label from its liner.
2. Press a corner of the sticky side of the label to the outer surface of the roll of ribbon.
3. Peel the label off of the ribbon.
4. Observe the results. Did flakes or particles of ink from the ribbon adhere to the label?
If ink from the ribbon...
Then...
Adhered to the label
The ribbon is coated on the outside and can be used with
the G-Series printer.

Printing with Externally Mounted Roll Media
40
Printing with Externally Mounted Roll Media
The G-Series printer accommodates externally mounted roll media similar to the printer’s
support of fan-fold media. The printer requires the media roll and stand combination to have a
low initial inertia to pull the media off the roll. The G-Series motor has 30% more torque than
the Zebra 2800 Series desktop printers to provide improved media handling and speed.
Zebra at this time does not offer an external media option for the G-Series printer.
Externally Mounted Roll Media Considerations:
• The media ideally should enter the printer directly behind the printer through the fan-fold
loading.
• Lower the print speed to decrease the chance of motor stalls. The roll typically has the
highest inertia when trying to start the roll moving. Larger media roll diameters require the
printer to have more torque applied to get the roll moving.
• The media should move smoothly and freely. The media should not slip, skip, jerk, bind
and then move, etc. when mounted on your media stand.
• The printer should not touch the media roll.
• The printer should not slip or lift up off the operating surface.

Fonts and Your Printer
41
Fonts and Your Printer
The G-Series printer supports your language and font requirements with a variety of internal
fonts, on-board font scaling, international font sets and character code page support, Unicode
support, and font download.
The G-Series printer’s font capabilities are programming language dependent. The EPL
programming language provides for basic bitmapped fonts and international code pages. The
ZPL programming language provides advanced font mapping and scaling technology to
support outline fonts (TrueType™or OpenType™) and Unicode character mapping as well as
basic bitmapped fonts and character code pages. ZPL and EPL programming guides describe
and document the fonts, code pages, character access, listing fonts, and limitations for their
respective printer programming languages. See the printer programming guides for
information on Text, Fonts and Character support.
The G-Series printer includes utilities and application software that support font download into
the printer for both printer programming languages.
Identifying Fonts in Your Printer
Fonts and memory are shared by the programming languages in the printer. Fonts can be
loaded in many memory areas in the G-Series printer. ZPL programming can recognize EPL
and ZPL fonts. EPL programming can only recognize EPL fonts. See the respective
programmer guides for more information on fonts and printer memory.
ZPL Fonts:
• To manage and download fonts for ZPL print operation, use ZebraNet Bridge.
• To display all of the fonts loaded in your G-Series printer, send the printer the ZPL
command ^WD. See the ZPL Programmers Guide for details.
•
•
•
•
Bitmap fonts in the various printer memory areas are identified by the .FNT file
extension in ZPL.
Scalable fonts are identified with the .TTF, .TTE or .OTF file extensions in ZPL.
EPL does not support these fonts.
The six fonts LMu.FNT through LMz.FNT are EPL Line Mode fonts and are not
available for use in EPL programming on thermal transfer G-Series printers.
When displayed in ZPL, the EPL Soft fonts have are separated into two groups-
horizontal and vertical. The EPL Soft fonts are noted with single lowercase alpha
characters (a-z) followed by an uppercase H or V and the .FNT file extension.
EPL Fonts:
• To download fonts for EPL print operation, use the EPL Font Downloader.
• To display Soft Fonts (ext.) available to EPL, send the printer the EPL command EI.
•
Asian Fonts in G-Series printers are displayed as Soft Fonts, but are still accessible as
documented in the A command in the EPL programmer’s guide.
•
All EPL fonts displayed are bitmap fonts. They do not include the .FNT file extension
or the horizontal (H) or vertical (V) designators that are displayed with the ZPL
command ^WD as described above in ZPL Fonts.

• To remove non Asian EPL fonts with EPL programming, use the EK command.
• To remove EPL Asian fonts from the printer, use the ZPL ^IDcommand.
Localizing the Printer with Code Pages
The G-Series printer supports two sets of language, region and character sets for permanent
fonts loaded into the printer for each printer programming language, ZPL and EPL. The printer
supports localization with common international character map code pages.
• For ZPL code page support, including Unicode, see the ^CI command in the ZPL
programmer’s guide.
• For EPL code page support, see the I command in the EPL programmer’s guide.
Asian fonts and Other Large Font Sets
Asian language pictographic fonts have large character sets with thousands of characters that
support single language code page. In order to support the large Asian character sets, the
industry adopted a double-byte (67840 maximum) character system instead of the single-byte
characters (256 maximum) used by Latin based language characters to address large font sets.
In order to address multiple languages with a single font set, Unicode was invented. A
Unicode font supports one or more code points (relate these to code page character maps) and
is accessed in a standard method that resolves character mapping conflicts. The ZPL
programming language supports Unicode; EPL does not. Both of the printer’s programming
languages support the large pictographic double-byte character Asian font sets.
Asian language support requires additional memory support by the G-Series printer configured
with the RTC and Full Flash Memory factory option. The number of fonts that can be
downloaded is dependent upon the amount of available flash memory not already in use and
the size of the font to be downloaded.
Some large Unicode fonts are too large to be installed in the printer with the RTC and Full
Flash Memory factory option such as MS (Microsoft) Arial Unicode font (23MB) or the
Andale font (22MB) offered by Zebra. These large font sets typically support a large number
of languages as well.
Getting Asian Fonts
Asian font sets are downloaded into the printer by the user or integrator. The fonts are
purchased separately from the printer.

Stand Alone Printing
43
Stand Alone Printing
Your printer can be configured to work without being attached to a computer. The printer has
the ability to automatically run a single label form. One or more downloaded label forms can
be accessed and run with a terminal or wedge device or a Zebra KDU (keyboard display unit)
to call a label form. These methods allow the developer to incorporate data input devices, such
as scanners or weight scales, to the printer via the serial port.
Label formats can be developed and stored in the printer to support labels that have:
• No data entry required and print when the Feed button is pressed.
• No data entry required and print when a label is removed from the printer’s optional label
dispenser.
• One or more data variables to be entered via the terminal or wedge device. The label will
print after the last variable data field has been input.
• One or more label formats that are called by scanning bar codes containing programming
to run a label form.
• Label forms designed to work as a process chain with each label including a bar code
containing the programming to run the next label in the process sequence.
Both printer programming languages support special label forms that will automatically run
after a power cycle or reset. The ZPL looks for a file named AUTOEXEC.ZPL and EPL
looks for a label form named AUTOFR. If both files are loaded in the G-Series printer, then
only the AUTOEXEC.ZPL will run. The EPL AUTOFR form runs until it is disabled. Both
files must be deleted from the printer followed by a reset or a power cycle to completely
remove the files.
Note • The G-Series EPL AUTOFR command can only be disabled with NULL character
(00 hex or ASCII 0). The G-Series printer will ignore the other character that normally
disables the AUTOFFR form operation in EPL printers, the XOFF character (13 hex or
ASCII 19).
The G-Series printer can source up to 750mA through the serial port’s 5 volt line; see
Appendix A for more information on the printer’s serial port interface.

Label Dispenser Option
The factory installed label dispenser option allows you to print a label with backing
(liner/web) being removed from the label as it prints, ready for application. When printing
multiple labels, removing the dispensed (peeled) label notifies the printer to print and dispense
the next label.
To use dispenser-mode correctly, use your printer driver to activate the label (taken) sensor
along with these typical label settings which include but are not limited to length, non-
continuous (gap), and web (liner). Otherwise, you must send the ZPL or EPL programming
commands to the printer.
When programming in ZPL, you can use the following command sequences shown below and
refer to your ZPL Programming Guide for more information on ZPL programming.
^XA ^MMP ^XZ

Cutter Option
The printer supports two factory installed media cutter options for full width cutting of label
liner, tag or receipt media. These cutter options are all supported in a single cutter housing
design. The type of cutter option installed in your printer can be verified by printing a printer
configuration status label. The cutter options are:
•
A medium duty cutter for cutting label liner and light tag media (LINER/TAG)
Maximum Paper Weight (thickness): up to 180 g/m2 (0.0077 in.)
Life*: 2 million cuts: 0.5 mil to 5 mil stock (10-120 g/m2)
1 million cuts: 5 mil to 7.5 mil stock (120-180 g/m2)
750,000 cuts: 7.5 mil to 10 mil (180-200 g/m2)
* - Exceeding the maximum media weight (density/hardness) and thickness will
shorten the cutters usable life or can cause the cutter to fail (jam or other error).
•
•
Cut Width: 4.25 inches (108 mm) maximum to 0.75 inches (19 mm) minimum
Minimum distance between cuts (label length): 1 inch (25.4 mm). Cutting shorter
media lengths between the cuts may cause the cutter to jam or error.
•
By default, the cutter operations include a self cleaning preventive maintenance
cleaning cut after every twenty-fifth cut. This feature can be disabled via ZPL or EPL
SGD (Set/Get/DO) programming command (cutter.clean_cutter) but is not
recommended.
Warning • There are no operator serviceable parts in the cutter unit. Never remove the
cutter cover (bezel). Never attempt to insert objects or fingers in to the cutter mechanism.
Important • Tools, cotton swabs, solvents (including alcohol), etc. all may damage or shorten
the cutter’s usable life or cause the cutter to jam.

Printers with the factory installed RTC (Real Time Clock) and Full Flash Memory option
allow you to create highly customizable printer applications, improve printer productivity and
flexibility, and provide extra memory to store more forms, graphics (logos), fonts, and the
large Asian font sets.
The RTC allows the label form developer to include:
•
•
•
•
Time Date Stamping
Pre or Post Dating
Allows Date/Time date to be included on printed form without altering the form
Provide dates and times without needing to generate them with the host system,
application software or programmatically by another process (e.g. a database report).
The RTC enhances the printer’s ability to operate in a stand-alone configuration (e.g. not
connected to a host or PC). A common use would be to provide a date stamp to a tag, ticket,
The RTC feature supports both ZPL and EPL printer programming. The two programming
behaviors that display the time and date are independent of each other. The commands that set
time and date change them for both printer languages.
Caution • The optional RTC assembly has a three volt lithium battery. You can discern a low
or flat battery if the printer provides a consistently delayed date stamp. Battery replacement
must be performed by a qualified service technician. Only use a Zebra approved replacement
battery.
Important • Recycle batteries according to local your guidelines and regulations. Wrap the
battery when disposing (or storing) to avoid a short circuit.
DO NOT short circuit the battery. Short circuiting the battery may result in heat
generation, fire or bursting.
DO NOT heat, disassemble or dispose of battery in fire.
The Full Flash Memory provides an additional 8 Megabytes to the printer’s standard
4 Megabytes of printer memory for a total of 12 Megabytes printer memory.

KDU — Printer Accessory
The KDU (keyboard display unit) is a small terminal unit that interfaces with the printer for
accessing EPL label forms stored in the printer.
The KDU is strictly a terminal and does not have the capability to store data or set up
parameters. The KDU is used for the following functions:
•
•
•
•
List label forms stored in printer
Retrieve label forms stored in printer
Input variable data
Printing labels
The KDU was designed for Zebra EPL printers. The EPL printer’s serial port was configured
for DCE (data communication equipment) communications configuration. The G-Series
printer has a DTE (data terminal equipment) serial port configuration. Because of the KDU
and G-Series have different wiring configurations, a KDU serial port adapter is needed to
properly supply power to the KDU and enable communications between them.

Cleaning the Printhead
Always use a new cleaning pen on the printhead (an old pen carries contaminants from its
previous uses that may damage the printhead).
Caution • The printhead becomes hot while printing. To protect from damaging the
printhead and risk of personal injury, avoid touching the printhead. Use only the cleaning
pen to perform maintenance.
When you load new media, you can also clean the printhead.
1. Rub the cleaning pen across the dark area of the printhead. Clean from the middle to the
outside. This will move adhesive transferred from the edges of media to the printhead
outside of media path.
2. Wait one minute before closing the printer.

Platen Cleaning and Replacement
The standard platen (drive roller) normally does not require cleaning. Paper and liner dust can
accumulate without effecting print operations. Contaminates on the platen roller can damage
the printhead or cause the media to slip or stick when printing. Adhesive, dirt, general dust,
oils and other contaminates should be cleaned immediately off the platen.
Clean the platen (and media path) whenever the printer has significantly poorer performance,
print quality or media handling. The platen is the print surface and drive roller for your media.
If sticking or jamming continues even after cleaning, you must replace the platen.
The platen can be cleaned with a fiber-free swab (such as a Texpad swab) or a lint free, clean,
damp cloth very lightly moistened with medical grade alcohol (90% pure or better).
1. Open the cover (and dispenser door). Remove media from platen area.
2. Pull the platen bearing latch release tabs on the right and left sides towards the front of the
printer and rotate them up.

3. Lift the platen out of the printer’s bottom frame.
4. Clean the platen with the alcohol moistened swab. Clean from the center out. Repeat this
process until the all of the roller surface has been cleaned. If there has been heavy
adhesive build-up or label jam, repeat with a new swab to remove residual contaminates.
Adhesives and oils, for example, may be thinned by the initial cleaning but not completely
removed.
5. Install the platen in the printer. Discard the cleaning swabs after use - do not reuse.
6. Make sure the bearings and drive gear are on the shaft of the platen.

Manual Calibration
Manual calibration is recommended whenever you are using pre-printed media or if the printer
will not correctly auto calibrate.
1. Make sure media is loaded.
2. Turn on the printer power.
3. Press and hold the Feed button until the green status light flashes once, then twice and
then continuing until the flash groups reach the group of seven flashes. Release the Feed
button.
4. The printer will set the media sensor for the label backing being used. After it is done
making this adjustment, the roll will automatically feed until a label is positioned at the
printhead. A profile of the media sensor settings (similar to the example below) will print.
Upon completion, the printer will save the new settings in memory and the printer is ready
for normal operation.
5. Press the Feed button. One entire blank label will feed. If this does not happen, try
defaulting (refer to the four-flash sequence in “Feed Button Modes” later in this chapter)
and recalibrating the printer.
Note • Performing a manual calibration disables the auto calibration function. To return to
auto calibration, default the printer (refer to the four-flash sequence in Feed Button Modes
on page 89 in this section).

effect.
Interconnecting to DTE Devices — The printer is configured as data terminal
equipment (DTE). To connect the printer to other DTE devices (such as the serial
port of a personal computer), use an RS-232 null modem (crossover) cable. Figure
31 shows the required cable connections.
Interconnecting to DCE Devices — When the printer is connected via its RS-232
interface to data communication equipment (DCE) such as a modem, a STAN-
DARD RS-232 (straight-through) interface cable must be used. Figure 32 shows
the connections required for this cable.
Connecting to the KDU (Keyboard Display Unit) — The KDU was designed for
DCE printer connections and requires a Zebra custom serial port gender changing
adapter. The KDU now includes the KDU adapter and the Zebra kit part number
for the KDU Adapter is 105934-088.
