Main PCB Circuit Diagram 3/5
1
Connector for the CIS
Power for the CIS LED array
Clock output
Trigger signal output. One shot of this signal triggers a line of scan.
LED control signal output circuit which controls the intensity of the CIS LED array.
1-5: Input of video data (VID) to the FAX engine
1-6: Clamp circuit that gives the bias level to the amplifier of the VID input circuit according to the CLAMP and CLPWM signals issued by the CPU (that monitors
the current video data input) for compensating the DC component of video signals for the next scan line
1-1:
1-2:
1-3:
1-4:
2
Connector for the thermal recording head
2-1: Power 26V for the thermal recording head
2-2: Thermister signals which are normalized by the resistor network and fed to the
FAX engine
2-3: Strobe signals
2-4: Data signals
2-5: Power 5V for the logic circuit of the thermal recording head
3
Connector for the motor
4
Connector for the solenoid (that switches the power transmission)
