UCLI72-4 Quad Charger  
The UCLI72-4 Quad Charger is designed to charge up to four  
QL Series battery packs simultaneously. Batteries must be re-  
moved from the printer to be charged in the Quad Charger.  
1. Ensure that the charger has been installed properly per  
the Quad Charger instruction manual. Ensure that the power  
indicator on the front panel is on.  
2. Remove any protective shrink-wrap and labels from all  
battery packs prior to use. Plug a battery pack into any one of  
the four charging bays as shown in Figure 4, noting the orien-  
tation of the battery pack. Slide the battery pack into the  
charging bay until it stops. Then rock the battery pack back  
until it snaps into place. The amber indicator directly under the  
battery being charged will turn on if the battery is properly in-  
serted.  
The indicators under the battery will allow you to monitor  
the charging process per the table below:  
Amber

Note: A fault condition is caused by a problem with the battery.  
The charger may indicate a fault because the battery is too hot or  
cold to charge reliably. Try to charge the battery again when it  
returns to the room’s ambient temperature. If the Amber indicator  
starts flashing on the second attempt, the battery should be  
discarded.

Battery packs which are only partially discharged will take  
less time to reach their charged state. Batteries which have  
reached 80% of their charge capacity may be used, however,  
it is recommended that you allow the batteries to reach a full  
charge to maintain maximum battery life.  
The UCLI72-4 Quad Charger has a safety feature which  
stops charging a battery after six hours regardless of  
its charge state.

Battery Safety  
Avoid accidental short circuiting of any battery. Allowing  
battery terminals to contact conductive material will create a  
short circuit which could cause burns and other injuries or could  
start a fire.  
Use of any charger not approved specifically by Zebra for use with  
its batteries could cause damage to the battery pack or the  
printer and will void the warranty.

Charger Safety  
Use care in locating the Quad Charger. Do not place it in  
locations where liquids or metallic objects may be dropped into  
the charging bays. Do not block the ventilating slots on the top  
and bottom covers. Ensure that the Charger is plugged into a  
power source which won’t accidently be turned off if you will be  
charging batteries overnight.

Loading the Media  
You can operate QL Series printers in one of two different  
modes: Tear-Off or Peel-Off. Tear-Off mode allows you to tear  
off each label (or a strip of labels) after it is printed. In Peel-Off  
mode, the backing material is peeled away from the label as it  
is printed. After you remove this label, the next one is printed.  
Installing the Media  
QL 420 and QL 220 Printers  
1. Open the printer: Refer to Figure 5 (QL 420 shown).  
• Press the latch release button on the side of the printer as  
shown at “1” below. The latch assembly will flip open  
automatically

2A. Load the media (continued):  
Loading media from an external supply. Refer to Figure 7.  
The QL 420 has a loading slot in the rear of the media com-  
partment which allows you to use standard 4” (101.6 mm)  
wide fan-fold media from an external supply. The external  
supply must be designed such that it does not exert excessive  
drag as media is fed through the printer, which could result in  
distorted printing.  
Zebra can provide a vehicle mount (p/n DC16620-1) de-  
signed specifically for the QL 420 which incorporates an exter-  
nal media supply bin.  
• Pull the media supports apart, insert a Media Spacer  
(Zebra part number BA16625-1) between them, and  
let the media supports close.  
Insert the media from the  
external supply through the  
rear feed slot, between the  
media guides and up  
through the media compart-  
ment as shown.  
Make sure the

Operator Controls  
QL Series printers are available with one of two possible  
control panels. The standard control panel is detailed below  
and in Figure 9. The optional control panel (Figure 10) fea-  
tures an LCD which allows easy display and selection of many  
printer functions detailed on following pages.  
Standard Keypad  
The standard keypad has three control buttons and two mul-  
tipurpose indicators.  
• The Power button turns the printer on and off.  
• The Feed button advances a length of media which is  
determined by the type of media being used. Label  
media will be advanced to the next gap or bar sense  
marker. Journal (plain) media will be advanced a length  
determined by the printer’s software.  
• The Function button is controlled by a printer’s specific  
application to support such functions as:  
Print a battery level report.  
Print the Local Area Network (LAN) status  
Print a Short Range Radio Frequency (SRRF) status  
Print a media supply report  
The green LED on the left side of the control panel indicates  
the status of several printer features:  
• A slowly blinking sequence indicates the printer’s battery  
needs charging.  
• Printers with a wireless QuickLink module installed: a  
quickly blinking sequence indicates the printer has not  
established a link to either a Local Area Network or a  
compatible wireless equipped terminal.  
• Printers with a wireless QuickLink module installed: A  
steadily lit indicator shows that the printer has established  
a wireless link, either to the LAN or to a compatible  
terminal.  
A steadily lit green indicator on a non-wireless printer is a  
power-on indicator.  
The yellow LED on the right side of the control panel has  
two indication conditions.  
• A rapidly blinking yellow LED and a chime indicate that no  
application has been loaded into the printer.

Verify the Printer Is Working  
Before you connect the printer to your computer or portable  
data terminal, make sure that the printer is in proper working  
order. You can do this by printing a configuration label using  
the “two key reset” method. If you can’t get this label to print,  
refer to “Troubleshooting”.  
Printing a Configuration Label  
1. Turn the printer off. Load the media compartment with  
journal media (media with no black bars printed on the  
back)  
2. Press and hold the Feed Button.  
3. Press and release the Power button and keep the Feed  
button pressed. When printing starts, release the Feed  
button.  
The unit will print a line of interlocking “x” characters to  
ensure all elements of the print head are working, print out the  
version of software loaded in the printer and then print two re-  
ports.  
The first report indicates model, ROM version, serial num-  
ber, baud rate, etc. The second report prints out more de-  
tailed information on the printer’s configuration and parameter  
settings. If no second report appears, there is no application  
loaded. (See the Troubleshooting Section for a sample print-  
out and a further discission on how to use the configuration  
label as a diagnostic tool.)  
Connecting the Printer  
The printer must establish communications with a host ter-  
minal which sends the data to be printed. Communications  
occur in four basic ways:  
• By a cable between the printer and its host terminal  
• Linking to a host terminal via Infrared (usually by means  
of the industry standard IrDA protocol)  
• By means of a Bluetooth™ short range radio frequency  
link.  
• By means of a wireless LAN (Local Area Network) per  
802.11b specifications.

Cable Communications  
connecting  
CAUTION. The power should be turned off before  
or disconnecting the communications cable.  
All QL Series printers can communicate by cable; the specif-  
ic cable supplied with your printer will vary with the host ter-  
minal. The 8- pin circular connector on your communications  
cable plugs into the serial communications port on the side of  
the printer. The connector is keyed to assure correct align-  
ment; do not try to force the cable if it does not plug in. The  
other end of the cable must be plugged into the host terminal  
as shown in Figure 11, or to a serial port on a computer (Fig-  
ure 12.) Communications between the terminal and the print-  
er are controlled by the applications running on the terminal  
and the printer.

IR Communications  
Printers equipped for infrared (IR) communications are iden-  
tified by a small “IR” logo on the unit’s label. IR allows wireless  
communications between the printer and the host terminal. IR  
units can also communicate with a cable as detailed above,  
however, IR functions are disabled when the cable is plugged  
in. Printers with the IR option can be configured to conform to  
the standard IrDA communications protocol  
Linking a Printer to an IrDA Host  
IrDA compliant terminals will automatically initiate communi-  
cations to the printer. First ensure that there is a direct line of  
sight between the printer and the terminal that will be sending  
data. The IR window on the front of the printer must face the  
corresponding window on the terminal to properly send and  
receive signals. An IrDA compliant terminal will seek out any  
linkable devices and establish communications between them,  
even turning the printer on if necessary.

Wireless Communications with Bluetooth™using ZBR-2 Radio  
The following section only applies when the Bluetooth Module (FCC ID: I28MD-BTC2TY)  
is installed in a QL series printer (note that only one of the radio options can be in-  
stalled in the printer at one time).  
“Bluetooth” is a worldwide standard for the exchange of data  
between two devices via radio frequencies. Bluetooth radios  
are relatively low powered to help prevent interference with  
other devices running at similar radio frequencies. This limits  
the range of a Bluetooth device to about 10 meters (about 32  
feet).  
Both the printer and the device it communicates with must  
follow the Bluetooth standard.  
Exposure to Radio Frequency Radiation  
The radiated output power of this internal Bluetooth radio is far  
below the FCC radio frequency exposure limits. Nevertheless, this  
Bluetooth radio must be used in such a manner that the antenna is  
2.5 cm or further from the human body.  
The radio and antenna are mounted internally in this printer such  
that when the printer is worn with the back of the printer against  
the body and the front of the printer (where paper exits) away from  
the body, then the 2.5 cm distance between the antenna and the  
users body will be met. Do not use the printer in an unauthorized  
manner.  
The internal Bluetooth radio operates within guidelines found in  
radio frequency safety standards and recommendations. The level  
of energy emitted is far less than the electromagnetic energy  
emitted by other wireless devices such as mobile phones.

Bluetooth™ Networking Overview  
In order to exchange data, two Bluetooth enabled devices  
must establish a connection. Bluetooth software is always  
running in the background, ready to respond to connection re-  
quests. One device (known as the master or the client) must  
request a connection with another. The second device (the  
slave or the server) then accepts or rejects the connection. A  
Bluetooth enabled QL series printer will normally act as a  
slave, but in theory any Bluetooth device can be either a mas-  
ter or a slave. This miniature network is sometimes referred to  
as a “piconet” and can consist of several Bluetooth enabled  
devices.  
For the most part, communications using the Bluetooth pro-  
tocol are initiated and processed without any operator inter-  
vention, much like the IrDA system described previously.  
Each Bluetooth enabled QL series printer has a unique Blue-  
tooth Device Address (BDA) loaded into its QuickLink module  
when manufactured.

of the module and can be read with the module installed.  
WARNING: Use of the QL 320 or QL 420 with the radio module  
marked with FCC ID: I28MD-QL3201 meets the FCC requirements  
for radio frequency (RF) radiation exposure in the standard body  
worn configuration with no minimum separation. In this  
configuration, which applies whether the belt clip or shoulder  
strap is used, the face of the printer from which paper is  
transported is facing away from the user’s body. The standard  
configuration must always be used when the printer is body worn.  
This configuration maintains the required 1 cm separation  
distance.  
The QL 320 and QL 420 with this radio option have been SAR  
tested. The maximum SAR value measured for the QL 320 was .604  
W/kg averaged over 1 gram.  
The maximum SAR value measured for the QL 420 was .899 W/kg  
averaged over 1 gram.

WLAN Overview  
QL series printers can be equipped with a radio in the stan-  
dard PCMCIA footprint using the industry standard 802.11 or  
802.11b protocol. These printers will have the FCC I.D. number  
of the radio on the product label. They allow wireless commu-  
nication as a node within a local area network, (LAN) and its  
wireless capabilities allow communications from any point  
within the LAN’s perimeter. Methods of establishing commu-  
nications to the printer will vary with each LAN application.  
QL 220 Network Printers with the CF module can be identi-  
fied by the text “Network Printer” and FCC ID number I28MD-  
QL4137 on the front of the unit.  
QL 320 and QL 420 printers with the PCMCIA module can be  
identified by the text “Network Printer” and FCC ID number  
“I28-QL420352” on the front of the unit.  
QL 320 and QL 420 printers with the Frequency Hopping PC-  
MCIA module can be identified by the text “Network Printer”  
and FCC ID: I28MD-QL3201 on the front of the unit.  
Methods of establishing communications to QL series print-  
ers will vary with each LAN application. General information  
on establishing WLAN communications can be found in either  
the ”CPCL Programmers Manual” or the “Quick Start Guide  
for Mobile Wireless Printers” available on-line at:  
http://www.zebra.com/SS/manuals.htm

Extending Battery Life  
• Never expose the battery to direct sunlight or tempera-  
tures over 104° F (40° C).  
• Always use a Zebra charger designed specifically for  
Lithium-Ion batteries. Use of any other kind of charger  
may damage the battery.  
• Use the correct media for your printing requirements. An  
authorized Zebra re-seller can help you determine the  
optimum media for your application.  
• If you print the same text or graphic on every label,  
consider using a pre-printed label.  
• Choose the correct print darkness, and print speed for  
your media.  
• Use software handshaking (XON/XOFF) whenever pos-  
sible.  
• Select Tear-Off mode whenever possible (Peel-Off mode  
uses more power).  
• If your printer has the optional LCD display, use the  
display backlight only when necessary. Turn it off when-  
ever it is not needed.  
• Pull the battery out of the printer if the printer won’t be  
used for a day or more and you’re not performing a  
maintenance charge.  
• Consider purchasing an extra battery.  
• Remember that any rechargeable battery will lose its  
ability to maintain a charge over time. It can only be  
recharged a finite number of times before it must be  
replaced.  
• Don’t print while the LI 72 Wall Charger is plugged into the  
unit. Unreliable battery charging can result.

Troubleshooting Tests  
Printing a Configuration Label  
To print out a listing of the printer’s current configuration fol-  
low these steps:  
1. Turn the printer off. Load the media compartment with  
journal media (media with no black bars printed on the  
back)  
2. Press and hold the Feed Button.  
3. Press and release the Power button and keep the Feed  
button pressed. When printing starts, release the Feed  
button.  
Refer to Figures 22 and 22a for a sample configuration print-  
out.  
Communications Diagnostics  
If there’s a problem transferring data between the computer  
and the printer, try putting the printer in the Communications  
Diagnostics Mode (also referred to as the “DUMP” mode). The  
printer will print the ASCII characters and their and their text  
representation (or the period ‘.’, if not a printable character) for  
any data received from the host computer  
To enter Communications Diagnostics Mode:  
1. Print a configuration label as described above.  
2. At the end of 2nd diagnostics report, the printer will print:  
“Press FEED key to enter DUMP mode”.  
3. Press the FEED key. The printer will print: “Entering DUMP  
mode”.  
NOTE: If the FEED key is not pressed within 3 seconds, the printer will print  
“DUMP mode not entered” and will resume normal operation.  
4. At this point, the printer is in DUMP mode and will print  
the ASCII hex codes of any data sent to it, and their text  
representation (or “.” if not a printable character).  
Additionally, a file with a “.dmp” extension containing the  
ASCII information will be created and stored in the printer’s  
memory. It can be viewed, “cloned” or deleted using the Label  
Vista application. (Refer the Label Vista documentation for  
more information.)  
To terminate the Communications Diagnostics Mode and re-  
turn the printer to normal operations:  
1. Turn the printer OFF.
