Fig. 2-1 Block Diagram Host computer Host computer Parallel I/F Main Logic Board RS232C I/F Gate array CPU EEPROM Head driver Lamp Dipswitch Motor driver Cutter driver Sensor circuit EPROM 256K × 8 bi[...]

– 12 – PRINCIPLES OF OPERATION (1) Main Logic Board The main logic board’s CPU passes data transmitted from the host computer into the local RAM. It then reads the data from the RAM, arranges it in accordance with the ROM program, and prints the results by issuing appropriate drive signals to the printer mechanism. [Block Descriptions] a.

– 14 – 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 thr[...]

– 15 – 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 control[...]

– 16 – PRINCIPLES OF OPERATION Fig. 2-5 Block Diagram of Drive IC 2-2-3. Head current control Although the thermal printhead has four different STROBE lines, in fact it uses only three strobe signals to control its 576 elements. Specifically, each signal drives 192 of these elements. The signal/element arrangement is shown below. Thermal Printh[...]

– 17 – PRINCIPLES OF OPERATION Strobe signals are output in one of five patterns, depending on the number of dot lines that are simultaneously ON. The following table shows each of the patterns. Figure 2-7 shows the timing for Pattern (5). Strobe Signal Output Pattern STB1 STB2 STB3 0 STB1+STB2+STB3 384 1 193 STB1+STB2+STB3 384 STB1+STB2 192 2 [...]

– 18 – 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 calculate[...]

– 19 – PRINCIPLES OF OPERATION Fig. 2-9 Timing Chart 2-3. Feed-Motor Drive Circuit The printer uses 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 excitation method. Figure 2-11 shows the fe[...]

– 21 – 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 1 At pow[...]

The following shows an IC3-equivalent circuit. Fig. 2-14 Equivalent Circuit, Voltage Detection IC Figure 2-15 shows the IC’s operational timing. The IC asserts a [...]

– 23 – 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 p[...]

– 24 – PRINCIPLES OF OPERATION 3-3. Detectors 1 Paper-Out Detector The paper-out detector (reflective photosensor) is located at the paper entry slit. The photosensor’s phototransistor remains ON while paper is present. It goes OFF when paper runs out, generating output of a paper-out signal. Fig. 2-18 Paper-Out Detector 2 Paper-Near-End Dete[...]

– 25 – PRINCIPLES OF OPERATION 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 4 Cover-Open Detector This detector senses whether the upper cover is open or[...]
