5 Avoid setting density too high for sensitive paper types. Excessive dark values may cause the paper to swell,
degrading the image quality.
6 Some thermal papers may fail to produce a strong image when running at 50mm/sec printing speed, even at
maximum density setting. If you have this problem, reduce the print speed to 25mm/sec.

SPECIFICATIONS AND OPERATION
5. Sensor Adjustment
There are three different sensors: the transmissive sensor (label start-position detector), the black-mark sensor, and the
paper-out sensor. Adjustment procedures are described below. First note the following general points.
• The transmissive sensor level requires precise setting. Because transmission rates vary widely among different
types of label paper, we recommend that the sensor be readjusted each time the user changes to a different paper
type.
• Because black marks are likely to be similar across different paper types, the black-mark reflective sensor may
not require readjustment each time the paper type is changed. But you will still have to adjust it if the new paper
has a different consistency or uses a different black-mark density, or if the paper-feed routing is changed.
• In most generally not necessary to adjust the paper-out sensor.

SPECIFICATIONS AND OPERATION
Sensor adjustment procedures are as follows.
1)
Remove the ROM cover, located beneath the paper-roll holding area.
2)
Hold down the FEED and ON LINE buttons while switching on the power, and continue to hold them down until
you hear a triple beep. (This will take about five seconds.) When you hear the triple beep, release the buttons to
enter sensor-adjustment mode.
a)
b)
c)
Reflective Sensor
• Insert a non-black area of paper into the mechanism’s sensor area.
• Rotate the main PCB’s reflective-sensor adjustment knob (VR4) to the point where the Head Up LED comes
on.
Paper-Out Sensor
• Insert a non-black area of paper into the mechanism’s sensor area.
• Rotate the main PCB’s paper-out-sensor adjustment knob (VR3) to the point where the Paper End LED switches
on.
Transmissive Sensor
• Insert the backing portion of a label sheet into the mechanism’s transmissive sensor area. (Insert the backing
part only, not the label itself.)
• Adjust the main PCB’s coarse (VR1) and fine (VR2) transmissive-sensor adjustment knobs to the point where
the Error LED comes on.
Note: When setting paper, be sure to lower the head so that it is close to its normal fixed position.
After the sensor has been adjusted, press the ON LINE switch to exit the sensor adjustment mode and return to the
normal operation mode.

SPECIFICATIONS AND OPERATION
6. Setting Memory Switches from the Control Panel
TheTSP400usesEEPROMmemoryswitchesinplaceofcorrespondinghardwareswitches.AllEEPROMswitchsettings
can be changed by software. A number of these switches are also changeable from the control panel.
(1) Paper-Feed Mode (Continuous or Next-Top)
When the feed mode is set to next-top, the printer can come online only if loaded with labels or marked paper. If the printer
fails to come online you will not be able to change the feed-mode setting by command; you will therefore have to change
it using the control panel.
1 Hold down the FEED and ON LINE buttons while switching on the power, and continue to hold them down until
you hear a double beep. (You will first hear a single beep, followed by a pause, followed by the double beep.)
Release the buttons immediately after hearing the double beep.
2 Press the ON LINE button to select continuous feed (the printer beeps once), or press the FEED button to select
next-top feed (the printer beeps twice). If you select next-top feed, the printer automatically starts paper feed
and looks for the next top.
(2) Sensor Mode
The printer may be set to use either the transmissive or the reflective sensor for next-top detection. You can make this
setting as follows.
1 Hold down the ON LINE button while switching on the power, then continue to hold it down until you hear a
double beep. (You will first hear a single beep, then a pause, then the double beep.) Release the ON LINE button
immediately after hearing the double beep.
2 Press the ON LINE button to select the reflective sensor (the buzzer beeps once), or press the FEED button to
select the transmissive sensor (the buzzer beeps twice).

To generate a test print (self-test), hold down the FEED button while switching on the power.
Note: The test print continues as long as the FEED button is held down.
8. HEX Dump
Set the printer into hex-dump mode as follows: hold down the ONLINE button and switch the power on, then release the
ONLINE button as soon as you hear a single beep. The printer is now set to print a hex dump of the data sent from the
host.
Note: The HEX Dump mode continues to be effective until the power supply is turned off.

9. Page/Line Mode Switch
The TSP400 series supports two entirely different command sets: “Page Mode” and “Line Mode.” You can select the
mode either by software or from the control panel. To select from the control panel, proceed as follows.
NOTE: This function will not become meaningful until Line Mode
software has been introduced.
1 Hold down the ON LINE button while switching on the power, then continue to hold it down until you hear a
triple beep. (This will take about five seconds.)
2 Press the ON LINE button to select Page Mode (the buzzer beeps once), or press the FEED button to select Line
Mode (the buzzer beeps twice).

The host computer sends eight bits of parallel data to CN3 when the printer is ready (when BUSY is LOW).
The data passes through the interface PCB and gate array, then moves into the CPU.
Printer signals from the CPU (ACK, ERROR, SELECTED, PAPER OUT, etc.) pass through the gate array and are output
over the appropriate connector pins.

THEORY OF OPERATION
2-2. Editing and Printing
2-2-1. Editing
The CPU reads data sequentially from RAM and edits it in accordance with program instructions stored in EPROM. The
edited data undergoes parallel-to-serial conversion in the gate array, and is then output to the thermal head’s drive
controller.
2-2-2. Thermal head
The thermal head contains 640 heat elements. Printing is carried out by switching these elements ON or OFF as required.
Note that Line Mode supports 600-dot printing only. During Line Mode operation, therefore, the logic always sends OFF
data to elements 1 to 20 and 621 to 640.
The thermal head contains a dedicated drive controller. The controller consists of a shift register, a latch circuit, and a
driver circuit, as illustrated below. The drive controller receives serial data (SI) from the drive control board in sync with
the CLOCK signal. The controller latches the incoming data (LATCH), then outputs it to the heat elements in sync with
the trailing edge of the STROBE signals. A data value of LOW corresponds to a heat-element value of ON.

2-2-3. Head current control
Heat buildup in the head during operation can cause print quality to degrade. To maintain uniform quality, the printer
varies the energizing time (time that STROBE remains LOW) in accordance with the head temperature.
The thermal head’s surface temperature is calculated based on the resistance value of an attached thermistor. Energizing
time is reduced at higher temperatures, as indicated in the figure 2-6.

Voltage is controlled by PA4 of the CPU, which goes HIGH or LOW to switch transistors DQ2 and Q2 ON or OFF. When
Q2 is ON, the motor receives +24V (VM). When Q2 is OFF, +5V is supplied to the motor via diode D1.

At power on, voltage-detector circuit IC4 (M51953BL) outputs a LOW signal from its OUT terminal. The signal
lasts for approximately 160ms, as determined by capacitor C2 (0.47µF):
T = 0.34 × C2 (pF) [µs] = 160ms
The LOW signal resets the CPU and the mechanism drive circuits, and sets S-RAM into backup state.

3. Printer Mechanism
3-1. Thermal Head
The TSP400 printers employ thermal line printing. The thermal head consists of a horizontal line of 640 heat elements.
These elements print one line of dots at a time as the paper passes over the head. The head is fixed in position; only the
paper moves.
The printer prints a dot by heating the corresponding heat element. The heated element causes a chemical reaction in the
coloring layer of the thermal paper, resulting in the formation of a visible dot.

3-2. Paper-Feed Mechanism
The paper-feed mechanism is comprised of the paper-feed motor, gear train, platen, and thermal head. The paper-feed
motor drives the gear train, which in turn rotates the platen. The platen carries the thermal paper past the thermal head.
The paper-feed motor is a PM (permanent magnet) type, 4-phase 48-pole step motor. A single step feeds the paper
approximately 0.125mm.

THEORY OF OPERATION
3-3. Detectors
(1) Paper-Out Detector
The paper-out detector is located at the paper entry slit. The detector consists of a reflective photosensor. The
photosensor’s phototransistor remains ON while paper is present. It goes OFF when paper runs out, generating
output of a paper-out signal.
(2) Black-Mark Detector
This detector senses black marks indicating print start positions. The detector is useful only with specially marked
paper. Like the paper-out detector, the black-mark detector consists of a reflective photosensor. The photosensor’s
phototransistor goes OFF when a black mark appears.

MAINTENANCE AND LUBRICATION
1. Maintenance
Proper maintenance is necessary to maintain printer performance and forestall potential problems. Please carry out
maintenance as described below.
1-1. Cleaning
(1) Surface dirt
Clear away dirt with a soft cloth. If necessary, apply a small quantity of alcohol to the cloth to improve cleaning
power. NEVER use thinner, trichlene, or ketone solvents, as these can cause damage to plastic components.
When cleaning, take care to avoid damaging or moistening of electronic parts, mechanical parts, and wires.
(2) Internal dust
For best results, use an electric vacuum cleaning device to remove dust from the inside of the printer. Note that such
cleaning may also remove lubrication; when you have finished cleaning, check lubrication levels and apply
lubricant as necessary.
1-2. Checks
There are two types of maintenance checks. Simple “daily checks” can be performed by users during the course of daily
operation. “Periodic checks” must be carried out by qualified service personnel.
(1) Daily checks
• Check whether dirt or other foreign matter has worked its way into the printer, and remove as necessary.
• Checkthethermalheadforexcessivedirt.Iftheheadisverydirty,cleanitwithacottonstickorasoftclothsoaked
in alcohol.
(2) Periodic checks
Periodic checks and lubrication should be carried out once every six months or once every million lines of printing.
• Check the integrity of springs.
• Clear dust from areas around the detectors.
