1. Outline

A block diagram of this printer is shown in Fig. 1-1. It consists of the control circuit centered around CPU, ROM,
RAM and peripheral circuits, interface circuit for interfacing with each host computer, operator panel circuit for
operating switch input and LED display, printer mechanism, auto cutter, and power circuit for furnishing power
supply to each part.

2. CPU Peripheral Circuits

1) CPU and ROM/RAM
The CPU M50734SP has a external memory type. Lower 8-bit address is fetched via the A0/D0 bus line by
the 8-bit latch LS373. The 128-KB ROM and 64-KB RAM are used for performing the backup operation for
power failure by the super capacitor. The ceramic oscillator is used as CPU clock and transmits 7.37 MHz.

CBM-710/720 Service Manual

Fig. 2-1 CPU and ROM/RAM Circuit

2) Initial Resetting and Power Failure Interrupt Circuit
The IC12 is an IC for generating the power failure interrupt signal and reset signal. When the power supply
voltage decreased due to power failure, etc. this IC performs the voltage inspection and stores all data in the
CPU buffer into RAM while printing.

8

CBM-710/720 Service Manual

As can be seen in the timing chart, it detects that Vcc decreased up to about 4.5 V for power failure and
generates the power failure interrupt signal and sends it to CPU. Upon receipt of the signal, CPU transmits
the data in its buffer to RAM. This processing is done within about 200 µs. After about 1 ms, the reset signal
is generated at IC12 and given to CPU, etc., causing all circuits to reset for prevention of explosive running.
When the power supply is turned on, reset is released after Vcc increases up to 4.5 V or more and then initial
setting is performed. The WD terminal of CPU is called “Watch Dog”, which is the output terminal used for
explosive running.

3. Printer Control Circuit

1) When L is output to the CPU port P31, the motor rotates and a timing pulse appears at the DP terminal of
CN5.

2) After rotation of the motor, printing starts in timing at which the port P34 is changed into L from H by the
home pulse of the printer.

3) In 9 ports of CPU output ports P20 to 27 and P30, the L pulse is output to the necessary port. Electricity is
applied once to the DOT solenoid for two timing pulses and characters are printed.

4) The paper is fed when the CPU port P33 becomes L in the specified timing.

5) Color is changed when the CPU port P32 becomes L in the specified timing.

Fig. 4-1 Cutter Control Circuit

The cutter control circuit is as shown in Fig. 4-1. In the cutter side, M indicates the motor and S the home switch.
The motor can make forward and reverse rotation by controlling X and Y inputs of the control circuit as shown in
the table below.

The timing chart is provided in Fig. 4-2. The rising of S when the motor makes forward rotation is the home
position, where the motor stops. For full cut, the blade returns to the home position with only forward rotation of
the motor after turn-around. For partial cut, on the way of cut after forward rotation of the motor, make reverse
rotation to return the blade. Then stop the blade at the home position by making forward rotation again.

6. Paper End Sensor Circuit

Fig. 6-1 shows the paper end sensor circuit. The reflection type photo-interrupter is used as a sensor. When some
paper is still left, the light reflected by paper strikes upon the photo-transistor; thus, the collector of the photo­transistor is L. When paper becomes short, no light is reflected, causing the collector to go H. As a result, the CPU
input port P40 becomes H, going into the paper end state.

BUSY : Signal for indicating if the printer is in the busy state; it goes into the busy state for H. (Positive

logic)

the printer stop. (Negative logic)

8. Serial Interface Circuit

As the serial interface specification, RS-232C and 20 mA current loop can be switched by the slide switch. It can
be switched by the user although fixed by setting at delivery time.

1) RS-232C

By using MAX232C for data receiving (RD), data transmitting and BUSY (DTR), data is transmitted and
received at level of RS-232C. The baud rates of 110 to 9600 bps can be selected by switching the DIP
switch.

2) 20 mA Current Loop

The photo coupler is used for transmitting and receiving. The photo coupler LED is used for receiving data
and the photo transistor for transmitting data.

3) DIP Switch Reading

The baud rate, word length, parity check, parity condition are set by the DTP switch.

4) Positive/Negative Power Supply for RS-232C

±12 V power supply is required for obtaining RS-232C voltage level. In this printer, however, as IC
MAX232C for interface is used, ±12 V is generated at the power circuit built in IC. Thus, no other power
supply is required.

The serial interface circuit diagram is shown in Fig. 8-1.

9. RS422A Interface Circuit

The RS422A interface circuit diagram is shown in Fig. 9-1. As can be seen in the figure, when TXD CONTROL is
L, the line driver IC14 becomes enable, going into the ready-to-receive state. At this time, the line receiver IC15
becomes disable. When TXD CONTROL is H, IC14 becomes disable, while IC15 becomes enable, going into the
ready-to-receive state. Communication is actually made through 2 lines although usually done through 4 lines
(including GND FG). These 2 lines are used for both transmitting and receiving of data.

10. Power Circuit

This power circuit supplies DC 5 V for the control circuit and DC 24 V for driving the printer mechanism. When
the POWER switch is turned on, the AC voltage is applied to the transformer T after noise is eliminated by the
capacitors C1 to C4 and noise filter NF. For the secondary voltage of transformer, all waveforms are rectified at
both the DC 5 V side and DC 24 V side. IC1 indicates the regulator IC and Tr1 the current boosting transistor
which can generate DC 24 V constantly. The constant voltage can be obtained by the diode connected to the base
side of Tr3 and Zener diode, while DC 5 V can be obtained by the Darlington-connected transistor Tr2 for current
boost. The diode D5 also serves as temperature compensation.

1. Maintenance and Handling

1) Precautions for Handling

(1) Precautions for use

Do not cut the paper other than the specified recording paper or do not pull the recording paper on the
way of cutting; otherwise, resulting in damage of the blade section and reduction of service life.

(2) Precautions for storage

Store the unit avoiding dust, dirt, high temperature and high humidity.

2) Cleaning

(1) Remove the dust of recording paper properly.

A good cleaning can be given by using the vacuum cleaner, etc.

(2) Use alcohol or benzine as a clearing solvent.

Thinner, trichlene, ketone, etc. may damage the plastic parts.

(3) After cleaning, lubricate as needed.

CBM-710/720 Service Manual

3) Lubrication

Lubrication is not especially required within 150,000 cuts.
However, the blade operates slow, oil is used up for cleaning, and disassembly, assembly and replacement
are made, lubrication should be required.

2. Mechanism and Principle of Operation

1) Outline of Mechanism

The AC-2 and AC-3 are designed as the DP-505 and DP-600 small dot printers and characterized by compact
and lightweight types. The mechanism of this unit consists of 4 blocks; frame, power transmission
mechanism, detector, and movable blade mechanism.

Motor Gear

CBM-710/720 Service Manual

The reduction gear train of this auto cutter is composed of the motor gear mounted onto the motor shaft,

worn, and two cutter gears. One rotation of the motor gear rotates the cutter gear by 7/520 (
(See. Fig. 1.)

2)-2 Detector
The detector is composed of the mechanism contract switch and cutter gear cam.
This detector detects the home position of the movable blade for partial cut (see Fig. 2), turn-around
position (see Fig. 3) and returned blade. It is turned on when the blade is at the home position and turned
off when the blade returns. The position where the detector is turned off from on after starting of the
movable blade is the turn-around position for partial cut.
