PRINCIPLES OF OPERATION

2-1-2. Parallel interface

Fig. 2-3 Parallel interface

When the printer is ready (BUSY is LOW), the host computer transmits eight bits of parallel data (DATA1,...,DATA8)

to CN4. The data passes through the gate array and moves into the CPU.

Printer signals from the CPU (ACK, ERROR, SELECT, PAPER OUT, etc.) pass through the gate array and are output

over the appropriate connector pins.

PRINCIPLES OF OPERATION

2-2. Data Arrangement and Printing

2-2-1. Arrangement

The CPU reads data sequentially from RAM and arranges this data in accordance with program instructions stored in

EPROM. The arranged data is then converted from parallel to serial form. The gate array then outputs the resulting serial

data to the drive controller in the thermal printhead.

2-2-2. Thermal printhead

The thermal printhead has 576 heat elements. Printing is executed by switching these elements ON and OFF as required.

The printhead contains a built-in dedicated drive controller. The controller consists of shift register, latch circuit, and

driver circuit, as illustrated below. The controller receives serial data (SI) from the gate array in sync with the CLK signal.

It latches this incoming data (by LATCH signal), then outputs the data to the elements in sync with the falling edge of

the STROBE signal. A data value of LOW corresponds to an element value of ON (generating print).

PRINCIPLES OF OPERATION

Fig. 2-7 Timing Chart

2-2-4. Head current control

Heat buildup in the thermal printhead 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 print head’s surface temperature is calculated based on the resistance value of the attached thermistor, and energizing

time is controlled accordingly.

2-2-5. Head burnout protection

Misoperation of the CPU may cause head current to remain on too long, resulting in burn damage to the elements unless

current is shut off by other means. The printer therefore includes a burnout protection circuit that automatically forces

current off at some fixed time tw following current startup. Control is implemented through the head’s BEO terminal,

which is active on HIGH; setting the terminal LOW forces current off regardless of the STROBE state.

PRINCIPLES OF OPERATION

2-4. Power-On Reset Circuit

The power-on reset signal initializes all elements so as to protect against possible operating errors at power-on. The signal

is held for approximately 160ms when power comes on. The reset circuit is shown below.

Fig. 2-13 Power-On Reset Circuit

Fig. 2-13 Power-On Reset Circuit

1At power-on, voltage detector IC3 (M51953BL) outputs a LOW signal from its OUT terminal. The signal is held

for approximately 160ms by the action of capacitor C9 (0.47µF), in accordance with the following relation:

T = 0.34 × C9 (pF) [µs] = 160ms

2The LOW signal generates reset of the CPU and gate array, and stops operation of the mechanism drive circuitry.

PRINCIPLES OF OPERATION

3. Printer Mechanism

3-1. Thermal Printhead

The TSP400 printers utilize thermal line printing. The thermal printhead consists of a horizontal line of 576 heat elements.

These elements print one line of dots at a time as the paper passes over the head. The printhead is fixed in position; only

the paper moves.

The printer prints a dot by heating the corresponding heat element. The heated element generates a chemical reaction in

the coloring layer of the thermal paper, resulting in the formation of a visible dot.

Fig. 2-16 Principle of Thermal Printing

3-2. Paper-Feed Mechanism

The paper-feed mechanism is comprised of paper-feed motor, gear train, platen, and thermal printhead. The paper-feed

motor drives the gear train, which in turn rotates the platen. The platen carries the thermal paper past the printhead.

The paper-feed motor is a PM (permanent magnet) type, 4-phase 48-pole step motor. 3 steps feed the paper approximately

0.125mm.

3 Head-Up Detector

This detector senses the position of the thermal printhead. The leaf switch closes when the printhead is in contact

with the platen, and opens when the printhead is separated from the platen.

Fig. 2-20 Head-Up Detector

4Cover-Open Detector

This detector senses whether the upper cover is open or closed. The leaf switch closes when the cover closes,

and opens when the cover opens.

Fig. 2-21 Cover-Open Detector

3-4. Auto-Cutter Drive circuit (on TSP242-24/120/230 only)

The TSP242 includes a guillotine-type cutter. The motor rotation direction determines whether the cutter executes a full

cut or a partial cut. (The partial cut leaves paper attached at one point.)

Note that Memory Switch 2 Bit 8 must be set ON to enable use of the cutter.

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.

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 this printer.

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.
