4. Print-Density Adjustment

Adjust the print density in accordance with the sensitivity of the paper being used. The adjustment procedure is as follows.

Fig. 1-5 Print-Density Adjustment

1Remove the interface cover, located the rear side of the printer. The cover fits into place; no screws are used.

2The density adjustor (variable resistor) is now accessible through the aperture located to the left of the interface

connector.

3Insert a screwdriver (regular or phillips-head) into the aperture and rotate as necessary. The adjustor has a

rotational range of approximately 180 degrees.

5Avoid setting density too high for sensitive paper types. Excessive dark values may cause the paper to swell,

degrading the image quality.

6Some 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.

– 9 –

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.

– 10 –

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) 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.

b) 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.

c) 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.

– 11 –

SPECIFICATIONS AND OPERATION

6. Setting Memory Switches from the Control Panel

The TSP400 uses EEPROM memory switches in place of corresponding hardware switches. All EEPROM switch settings

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.

1Hold 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.

2Press 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.

1Hold 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.

2Press 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).

– 12 –

SPECIFICATIONS AND OPERATION

7. Test Print

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.

– 13 –

SPECIFICATIONS AND OPERATION

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.

1Hold 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.)

2Press 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).

– 14 –

SPECIFICATIONS AND OPERATION

10. Exposing the Peripheral Unit Connector

When operating in Line Mode, the printer can use the peripheral unit connector to drive a cash drawer or other such external

device. But note that the connector is originally hidden by a portion of the interface cover.

Fig. 1-6 Peripheral Unit Connector

To prepare the connector for use, remove the “connector cover” portion of the interface cover (see illustration) by gently

bending and breaking it with a pliers. Be sure to remove any remaining burrs using a cutter or other such tool.

SPECIFICATIONS AND OPERATION

11. Changing the Interface Board

You can change the printer’s interface by replacing the interface board. The replacement procedure is as follows.

Fig. 1-7 Changing the Interface Board

1Remove the interface cover, located on the rear side of the printer.

2Remove the three screws holding the interface board in place.

3Remove out the board by pulling on the pull sheet fastened to the connector.

4Fit the replacement interface board to the guides and push all the way in so that the connector is fully engaged.

5Fasten the outer plate to the printer with three screws.

6Replace the interface cover.

Note: The printer automatically detects changes in interface type.

2-1-3. Parallel interface

Fig. 2-4 Parallel Interface

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.

– 24 –

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.

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.

THEORY OF OPERATION

2-3. Feed-Motor Drive Circuit

The printer employs a 4-phase step motor (phase 1-2 excitation) to implement paper feed. The motor rotates through a

certain angle each time it receives a pulse from the drive circuit. The following diagram illustrates the phase 1-2 excitation

method. Diagram 2-8 shows the feed-motor drive circuit.

Fig. 2-8 Motor Control by Phase 1-2 Excitation

Fig. 2-9 Feed-Motor Drive Circuit

Voltage to the motor is controlled to produced the required action, as follows.

Mode Voltage Action

Operating VM (+24V) Drives the motor

VL (+5V)

Idle VL (+5V) Holds the motor

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.

THEORY OF OPERATION

2-4. Power-On Reset Circuit

Immediately following power-on the printer executes a power-on reset, initializing all circuit elements. The power-on

reset serves as protection against operational errors. The power-on RESET signal is maintained for approximately 160ms.

The reset circuit is illustrated below.

Fig. 2-10 Power-On Reset Circuit

1At 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 voltage-detection IC (IC4 in Fig. 2-10) detects momentary drops or unstable levels in the +5V line voltage. IC4

operation is illustrated by the equivalence circuit shown below.

Fig. 2-11 Equivalence Circuit for Voltage Detecting IC

Fig. 2-11 shows the operational timing. If the +5V line voltage falls below 4.25V, the IC produces a reset signal at its

OUTPUT terminal, resetting the CPU and the gate array.

THEORY OF OPERATION

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.

Fig. 2-13 Principle of Thermal Printing

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.

Fig. 2-15 Paper-Out Detector Fig. 2-16 Black-Mark Detector

(3) Label Detector

The transmissive detector is used to detect print-start positions for labels. It operates by detecting the difference

in light transmission between backing-only and backing-plus-label portions of the paper.

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.

• Check the thermal head for excessive dirt. If the head is very dirty, clean it with a cotton stick or a soft cloth soaked

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.

MAINTENANCE AND LUBRICATION

2. Lubrication

Proper lubrication is essential for maintaining the printer’s performance level and preventing breakdowns or other

problems.

2-1. Lubricants

Choice of lubrication can significantly affect the printer’s performance, longevity, and low-temperature characteristics.

We recommend the following lubricant for the TSP400 series.

Type Name Manufacturer

Grease Molykote EM Dow Corning

2-2. Application Method

If you are lubricating parts during disassembly or reassembly, be sure to wash or wipe the parts thoroughly to remove all

dirt and dust prior to lubricating.

Remember that cleaning can remove necessary lubrication. Always lubricate after cleaning, disassembly, or replacement.

2-3. Lubrication Points

Apply lubricants at the following locations. (Refer to Diagram 4-1.)

No. Location

1 Contact area of pressure bar and pressure pin

2 Contact area of gear 15×50×0.5 and gear shaft

3 Contact area of gear 58×0.5 and gear shaft

4 Contact area of gear 15×50×0.5 and PF motor gear
