CBM-710/720 Service Manual 6 Chapter 2 Cir cuit Description.
CBM-710/720 Service Manual 7 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 circui.
CBM-710/720 Service Manual 8 2. CPU Peripheral Cir cuits 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 .
CBM-710/720 Service Manual 9 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.
CBM-710/720 Service Manual 10 3. Printer Contr ol Cir cuit 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 .
CBM-710/720 Service Manual 11 4. Cutter Control Cir cuit Cutter Side Fig. 4-1 Cutter Control Cir cuit 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 .
CBM-710/720 Service Manual 12 5. Interface with Operation Panel As shown in Fig. 5-1, the operation panel circuit has the on-line switch and line feed switch. Each switch is connected to CPU input ports and each LED is connected through the driver to CPU output ports.
CBM-710/720 Service Manual 13 6. Paper End Sensor Cir cuit 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 photo- transistor is L.
CBM-710/720 Service Manual 14 7. Parallel Interface Circuit This circuit conforms to the standard interface. Description will be made for each signal of interface connector as follows. Fig. 7-1 shows the data input and print timing chart and Fig. 7-2 the parallel interface circuit diagram.

CBM-710/720 Service Manual 16 8. Serial Interface Cir cuit As the serial interface specification, RS-232C and 20 mA current loop can be switched by the slide switch.
CBM-710/720 Service Manual 17 Fig. 8-1 Serial Interface Circuit Dia gram.
CBM-710/720 Service Manual 18 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.
CBM-710/720 Service Manual 19 10. Power Cir cuit 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 .

CBM-710/720 Service Manual 21 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.
CBM-710/720 Service Manual 22 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.
CBM-710/720 Service Manual 23 2)-3 Movable blade mechanism The movable blade is changed into a linear motion by the crank pins and starts cutting the recording paper . (1) Full cut Cam Switch Cutter Gear Fig. 2 Fig. 3 Blade Crank Pin Fig. 4 At full cut, the crank pins turn one time and return to the home position.
CBM-710/720 Service Manual 24 3. Repairing (T roubleshooting) For troubleshooting, the repairing method will be explained by classifying the items as shown below . Make sure of the cause according to the items and find out the trouble portions for repairing.
CBM-710/720 Service Manual 25 1. The motor does not rotate. 2. The recording paper cannot be cut. Phenomenon Condition Cause Check Point and Method T roubleshooting • The motor does not rotate even if the rotation command is entered. • The motor operates temporarily and stops when the rotation command is entered.
CBM-710/720 Service Manual 26 4. Disassembly/Assembly 1) Disassembling Procedure Perform the disassembly in a reverse manner of the assembling procedure. 2) Assembling Procedure Perform the assembly according to the assembling procedure as shown in the separate table.
