THEORY OF OPERATION Block Diagram The block diagram of this printer is shown in Fig. 2-1. Fig. 2-1 Block Diagram Main Logic Board This board receives data from the host computer and stores it in the RAM in the order of arrival. The CPU on this board reads the data from the RAM, and edits it according to the program stored in the ROM.
THEORY OF OPERATION Main Logic Board 2-1. Data Input Operation 2-1-1. Parallel Interface Communications between the host computer and this printer are facilitated via parallel connectors. This section explains the handshake of this interface. The data input circuit of this interface is shown in Fig. 2-2. Fig.
THEORY OF OPERATION Fig. 2-3 Timing Chart of Parallel Interface 2-1-2. Serial Interface (option) When the serial interface is used, an optional Serial-Parallel Converter is required to be installed. The converter will change the voltage level (RS-232C <------> TTL) and the data transfer method (Serial <------> parallel). Fig.
Page 26
THEORY OF OPERATION The IC101 is a dual RS-232C driver/receiver which includes a capacitive voltage generator to supply RS-232C voltage levels from a single 5V supply. Data from the host computer is sent from RXD via IC101 and is input to the MPU. Serial data input to the MPU is converted into parallel data, and output to the main logic board.

THEORY OF OPERATION 2-2. General Flow Chart A general flow chart of editing and printing operations is presented in Fig. 2-7. Fig. 2-7 General Flow Chart of Editing and Printing – 24 –...
THEORY OF OPERATION 2-2-1. Editing Data stored in the RAM is read out sequentially by the CPU and then edited according to a function code that has been specified in advance. This editing takes places until the CR or CR + LF code appears or the line buffer becomes full. 2-2-2.
THEORY OF OPERATION Fig. 2-9 Print Head Temperature Detection Circuit 2-2-4. Carriage Motor Driving Circuit This printer employs a stepping motor as the carriage motor. Unlike regular motors on the market, this stepping motor will not operate just by connecting it to a power source. The motor operates only when a drive pulse is fed to it, but even then, it turns only a certain angle.
THEORY OF OPERATION 2-2-5. Carriage Motor Speed Control Since the carriage motor is a stepping motor, the carriage can be stopped at a desired position by controlling acceleration and deceleration. The carriage can also move backward. The rotational speed of the carriage motor is set by the number of pulses per time unit. The character pitch (horizontal character size) in each print mode is determined by changing this rotational speed (or carriage transfer speed).
Page 32
THEORY OF OPERATION Fig. 2-13 Paper Feed Motor Driving Signals The utilization of voltage applied to the paper feed motor is described as follows. Mode Voltage Application Operation +25VDC Motor Drive Standby: +5VDC Holding Bias Voltage to the paper feed motor is changed by setting CPU port P31 to LOW or HIGH and by turning transistors TR4 and TR5 ON or OFF.
THEORY OF OPERATION 2-3. Reset Circuit The RESET signal initializes the circuit elements and prevents operation errors when the power is turned on. The RESET signal is output for approx. 34ms. when the power is turned on, or while the RESET ( INPUT-PRIME ) signal is being output from the host computer.
THEORY OF OPERATION 2-4. Reset by +5V Line Voltage Detection A voltage-detecting IC (IC3 in Fig. 2-14) detects momentary drops in voltage or unstable voltage supply (due to power failures, etc.) on the +5V line. If the voltage on the +5V line falls below 4.25V, the RESET signal appears at the output terminal of the voltage-detecting IC.
THEORY OF OPERATION Power Supply Unit Fig. 2-17 shows the power supply unit. The AC power is stepped down to Vs1 and Vs2 by the power transformer. The Vs1 power is full-wave rectified by the DB1 rectifier stack and smoothed by electrolytic capacitor C4. The smoothed DC power is converted into the stable 25VDC power by the chopper circuit, whose main component is IC1.
Page 36
THEORY OF OPERATION We will explain the chopper circuit in terms of Fig. 2-18, a simplified version of Fig. 2-17. IC1 is a pulse-width control switching regulator. It has a reference voltage section, oscillation section, pulse-width control section, and power transistors.
THEORY OF OPERATION Mechanism 4-1. Print Head Mechanism The print head consists of 9 needle wires and 9 print solenoids. The following explains how each needle wire operates during printing. When the print solenoid is energized, the clapper is attracted by the iron core and the needle wire is driven toward the platen.
THEORY OF OPERATION Fig. 2-21 Print Head Carrying Mechanism 4-3. Ink Ribbon Feed Mechanism The ink ribbon feed mechanism is linked to the print head carrying mechanism described previously so that the ink ribbon is wound up automatically while the carriage moves left or right. The ribbon feed mechanism is driven by torque from the carriage motor, and carriage movement allows the gear B to rotate.
THEORY OF OPERATION 4-4. Paper Feed Mechanism The paper feed motor is a PM (Permanent Magnet) type, four-phase and 48-pole pulse motor. Minimum paper feed is set at 1/432 inch. There are two ways of feeding paper available with this printer: Friction method and Tractor method. You can select one of the two methods, using the release lever.
THEORY OF OPERATION 4-5. Detectors Home Position Detector A photo-interrupter is used in the home position detector, which is set at the left side of the frame unit. ON/OFF signals are generated according to the position of the shield plate mounted at the base of the carriage, and the printing position is determined by these signals.

CHAPTER 3 ADJUSTMENTS This printer has undergone various adjustments so that it will achieve standard performance. In this chapter, a brief explanation is given of the methods of adjustments. Follow the instruction when making maintenance inspections or when replacing parts to correct malfunctions. Gap Adjustment Between Print Head and Platen ..........
Page 43
ADJUSTMENTS Gap Adjustment Between Print Head and Platen 1-1. Measuring Gap Between Print Head and Platen Remove the upper case unit according to procedures described in Chapter 4. Set the index lever [1] at step two. Remove the ribbon guide [2]. Insert a thickness gauge [3] between the print head [4] and the platen [5], and measure the gap.
Page 44
ADJUSTMENTS Adjustment of Timing Belt Tension The timing belt tension should be set at from 15g to 19g. (The belt tension must be measured with the designated tension gauge [1].) After the belt has been used for a long time, however, it may be difficult to maintain prescribed tension because of belt deterioration or wear.
