Specifications
D014/D015/D078/D079 7-40 SM
PCB12
CNB (Connector
Board)
Sorts and routes signals to electrical components.
PCB13 IDCB: C1
One of two ID control boards at the base of the Cyan
STC. The CPU reads the board to confirm that the
correct STC is inserted into the correct bin.
PCB14 IDCB: M1
One of two ID control boards at the base of the Magenta
STC. The CPU reads the board to confirm that the
correct STC is inserted into the correct bin.
PCB15 IDCB: K1
One of two ID control boards at the base of the Black
STC. The CPU reads the board to confirm that the
correct STC is inserted into the correct bin.
PCB16 IDCB: Y1
One of two ID control boards at the base of the Yellow
STC. The CPU reads the board to confirm that the
correct STC is inserted into the correct bin.
PCB17
SBU (Sensor Board
Unit)
Contains the CCD. Converts CCD analog signals to
digital signals.
PCB18
SIOB (Scanner
Interface Board)
Controls all the sensors in the scanner unit and controls
the carriage drive stepping motors.
PCB19 Lamp Regulator
Converts the dc power input to a stable, high frequency
ac output to the exposure lamp.
PCB20 VBCU
VBCU: 1) Engine sequence control (all sensors, motors,
fusing temperature monitoring circuits), 2) Scanning
control, 3) Exposure control, 3) Image processing
control, 4) GW controller I/F, 5) Peripheral timing
control.
The I/O control board controls 1) Input/output ports for
all sensors, motor, solenoids, 2) drivers, 3) high voltage
power supply for PWM, and 4) analog input signals.
