2.1 Block DiagramThe block diagram of this printer is shown in Figure 2-1.

Fig. 2-1 Block Diagram

1. Main Logic BoardData output from the host computer goes through the interface of the control board and is stored in the RAMby the CPU. Then, the CPU reads data in the RAM and edits according to the program stored in the ROM.Upon completion of editing, the CPU outputs the various kinds of drive signals to the printer mechanism andgets the printer to start printing.

• Controls this printer.b. EPROM 27256 32K-bytes

• Contains the program which executes control of the printer.c. Interface circuitd. Gate array (parallel interface only)

• Inputs or outputs several signals.e. Driver

• The data edited by the CPU and gate array are sent to the printer mechanism after conversion to the signalfor the print head drive, carriage motor drive, and paper feed solenoid drive respectively.

2. Printer MechanismThe printer mechanism is made up of a print head, carriage motor, paper feed solenoid, ribbon shift solenoid(only for SP216/246) and detectors.

2.2 Main Logic Board2.2.1 Interface Circuit2.2.1.1 Serial Interface (RS-232C)

When the voltage level is changed on this circuit (RS-232C↔TTL), the data transfer method (Serial↔Parallel)also changes.IC3 is a dual RS-232C driver / receiver which includes a capacitive voltage generator to supply RS-232C voltagelevels from a single 5V supply.Data from the host computer is sent from the RXD terminal to IC3 and is input to the CPU. Serial data input tothe CPU is converted into parallel data in the CPU.

Fig. 2-2.A Serial Interface

THEORY OF OPERATION

2-4

2.2.1.2 Parallel Interface

Communications between the host computer and this printer are facilitated via parallel connector.This section explains the handshake of this inerface.The data input circuit of this interface is shown below.

Fig. 2-2.B Parallel Interface

The following is an explanation of this handshake.(1) When the BUSY signal is LOW (Ready), the host computer outputs 8-bit data 0 through 7 to the connector

CN1. Pin 1 carries the STROBE pulse signal from the host computer to the printer. This signal is normallyheld HIGH by the host computer. When the host computer has data ready for the printer, it sets this signal toLOW for at least 0.5 µs.

(2) The gate array of the main logic board reads data 0 through 7 at the time of STROBE signal fall, and thenturns the BUSY and I-BUSY signals to LOW.

(3) When the BUSY signal of the gate array is set to LOW, the BUSY signal of connector CN1 will be turnedto HIGH, notifying the host computer that data cannot be accepted. When the I-BUSY signal becomes LOW,the CPU is notified that STROBE signal has fallen and the gate array data will be read into the CPU.

(4) Upon completion of the data reading, the CPU notifies the host computer of the data receivable state by settingthe BUSY signal of connector CN1 and the ACK signal to LOW for a certain period of time.

2.2.2 Print Head Driving CircuitIn the parallel model, edited print data is output from HD1 ~ HD7 in the Gate Array (IC3).In the serial model, edited print data is output from P50 ~ P56 in the CPU (IC6).This allows the print data to be output to HD1 ~ HD7. When the print data (HD1) is low, the transistor TA1will be turned ON for 360 µs, energizing the print head solenoid to drive the print head.

THEORY OF OPERATION

2.2.3 Print Head Temperature Detection CircuitThe print head temperature detection circuit protects against damage when the print head heats up abnormally.Figuer 2-4 shows this circuit.The print head has a thermistor to show the temperature of the head solenoids. This thermistor is an element thatchanges its resistance value according to temperature. Its output voltage is input to an analog pin of the CPU. TheCPU compares this input voltage against its reference voltage VRFE (+5V) to evaluate the temperature of the headsolenoids and carries out one of the following operations depending on the temperature.1. T<105°C

• Bi-directional printing2. 105°C T

• Stop the printing operation and power lamp blinks. When the thermistor's temperature falls below 105°C,bi-directional printing is resumed.

THEORY OF OPERATION

2-7

2.2.4 Carriage Motor Driving CircuitThis printer employs a DC motor as the carriage motor. The DC motor has Drive operating mode and no Brakeoperating mode.

In the serial model, the LOW signal is output to IC6 P82 and causes the CR motor to start.

In the parallel model, the HIGH signal is output from the output terminal of the gate array and causes the CRmotor to start.

Figure 2-5.A.B. shows the carriage motor driving circuit.

Fig. 2-5.A Carriage Motor Driving Circuit [Serial]

Fig. 2-5.B Carriage Motor Driving Circuit [Parallel]

THEORY OF OPERATION

2-8

2.2.5 Paper Feed Solenoid Driving CircuitThis printer employs a clutch solenoid for paper feed. When power is supplied to the clutch solenoid, the triggerwill release the clutch pawl gear and activate the clutch mechanism to get the paper feed clutch to rotate. The paperfeed gear is in the paper feed clutch and gets the control cam to rotate. When the paper feed gear rotates, it rotatesthe paper feed roller and feeds the paper by 1/6 of an inch.

Fig. 2-6.A Paper Solenoid Driving Circuit [Serial]

Fig. 2-6.B Paper Solenoid Driving Circuit [Parallel]

THEORY OF OPERATION

2-9

The utilization of voltage applied to the paper feed solenoid is +24V.In the serial mode, P80 in the port of the CPU is switched between HIGH and LOW and this turns OFF and ONthe transistor array TA2.When TA2 is on, the +24V are supplied to the solenoid via the transistor array TA2.In the parallel mode, the same control described above is performed by the terminal of the gate array of IC3.

2.2.6 Power On Reset Circuit

The power on reset signal initializes the circuit elements and prevents operation errors when the power is turnedon. The power reset signal is output for approxmate 7.4 ms when the power is turned on.

Fig. 2-7 Power On Reset Circuit

a. When the power is turned on, the RESET signal is output from the terminal 5 of IC9 (M51953BL) for approximate7.4 ms. This is determined by external capacitor C26 (0.022µF), and it can be calculated by the following formula.T = 0.34 × C26 (pF) [µsec.] = 7.4 msec.

b. This LOW signal triggers RESET terminal of the CPU and gate array.c. Reseting the CPU and gate array will cause all the drive signals for carriage motor, the paper feed solenoid,

peripheral units and the print head to be ignored, preventing operation errors when the power is switched on.

THEORY OF OPERATION

2-10

2.2.7 Protection Circuit1. A voltage detecting IC (IC9 in Figure 2-7) 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 signalappears at the output terminal of voltage detecting IC.

Fig. 2-8 Equivalent Circuit of Voltage Detecting IC Fig. 2-9 Operational Timing Chart

2. This CPU has watch dog timer function, which is a timer that issues an interrupt if the CPU malfunctions(lost-micro). This interrupt tells the CPU that there has been a malfunction and it executes its malfuncrionprogram. (It cuts off the signals to the print head and the carriage motor, sets the ERROR signal low, etc.)

THEORY OF OPERATION

2-11

2.2.8 Ribbon Position Detection Circuit and Ribbon Color Selection Driving Circuit (only forSP216/246)

This printer employs a ribbon shift solenoid for switching the ribbon colors. When power to the ribbon shift solenoidcomes on, the trigger comes out from the clutch pawl wheel and the clutch mechanism activates so that the camgear rotates. There is a cam which changes the ribbon position up and down on the cam gear. The ribbon coloris switched by rotating this cam.

The ribbon position detector consists of the machanical SW.

When the ribbon is black, the mechanical SW comes ON.

2.3 Power Supply Unit2.3.1 Dropper Type (Ver.1)As the figure below shows, the power supply unit consists of the fuse circuit, transtormer, and power supply circuit.

Fig. 2-11 Power Supply Unit Configuration

2.3.1.1 Fuse Circuit

The AC power passes through the fuse, is filtered by C1, passes though the LC noise prevention circuit, and isfed to the primary winding of the transformer.

Fig. 2-12 Fuse Circuit

2.3.2 Switching Type (Ver.2)

The design for the current dropper type power supply has been changed to a switching type power supply with theobjectives of attaining a more compact and lighweight device and improving power conversion efficiency.

THEORY OF OPERATION

2-14

2.4 Mechanism2.4.1 Print Head MechanismThe print head consists of 7 needle wires and 7 print solenoides. The following is an explanation of the operationof a single needle wire during printing.1. When the print solenoid is energized, the clapper is attracted by the iron core and the needle wire is driven toward

the platen.2. This needle wire hits the platen via the ink ribbon and paper and a single dot is printed on the paper.3. When the print solenoid is de-energized, the needle wire is returned to its original position by rebound energy

and by the force of the spring and clapper holder (leaf spring).

Fig. 2-13 Outline of Print Head Mechanism

THEORY OF OPERATION

2-15

2.4.2 Print Head Carriage Mechanism

The print head carriage mechanism consists mainly of the carriage, carriage motor, gear train, home positiondetector, and timing detectors. When the carriage motor rotates, the drive shaft (cylindrical cam) is rotated by thereduction gear. The print head supported by the carriage moves right and left. The print head position is determinedby timing signals generated by the timing detectors and the home position signal generated by the home positiondetector.

Fig. 2-14 Print Head Carrying Mechanism

THEORY OF OPERATION

2-16

1. Timing Detectors 1 and 2

These detectors consist of the pulse generator attached to the motor shaft, the photo-interrupter on the timingdetector board, and the waveforming circuit. When the pulse generator cuts off the light from the photo-interrupterLED, the photo-interrupter’s photo-transistor goes off.

2. Home position detector

The home position detector is composed of a mechanical switch. When the carriage is at the home position, themechanical switch goes ON.

2.4.3 Paper Feed Mechanism

The paper feed mechanism comprises of the carriage motor, the paper feed solenoid, the paper feed clutch, thegear train, the paper feed roller, and the holder roller. The gear train transmits the rotation of the carriage motorto the paper feed roller. By applying power to the paper feed solenoid, the clutch mechanism activates and the paperfeed clutch rotates. The paper sandwiched between the paper feed roller and the holder roller is driven upwards.One step of the paper feed solenoid drives the paper 1/6 inch.

Fig. 2-16 Paper Feed Mechanism

THEORY OF OPERATION

2-18

2.4.4 Ink Ribbon Feed Mechanism

The ink ribbon feed mechanism comprises of the ribbon cartridge, the carriage motor, the drive shaft, and the geartrain. The gear train transmits the rotation of the carriage motor to the ribbon shaft. The ribbon is contained inthe ribbon cartridge and tied into an endless loop. When the ribbon shaft turns the ribbon feed roller, the ink ribbonsandwiched between the ribbon feed roller and the ribbon pressure roller is wound up. The ribbon brake springkeeps slack out of the ribbon.

THEORY OF OPERATION

2-19

2.4.5 Detectors

Besides the timing detectors and home position detector discussed in 2.4.2, there are also the following detectors:

1. Paper out detector

The paper out detector is installed on the printer mechanism.When there is paper, the leaf switch is closed, but when the paper runs out, it is open.

Fig. 2-18 Paper out Detector

2. Ribbon Position Detector (only for SP216)The ribbon position detector is attached to the lower terminal PCB which is located at the ribbon base (W). Whenselecting black (at the time of shift down), the leaf switch is “CLOSED”. When selecting red (at the time of shiftup), the leaf switch is “OPEN”.

2.4.6 Ribbon Color Selection Mechanism (only for SP216/246)

This ribbon color selection mechanism comprises the carriage motor, gear train, ribbon shift solenoid, cam gearand the ribbon base (W). The rotation of the carriage motor is transmitted to the cam gear by rotating the geartrain. Then the ribbon shift solenoid is turned on by the ribbon color selecting command, the trigger comes outfrom the clutch pawl wheel and the cam gear rotates half a turn, and the cam is driven up and down, and the ribboncolor is changed.
