Parts
Outputs the key operation signals.
Controls the whole operation unit. (Displays information from the PCU PWB, and
sends operation information to the PCU PWB.)
Outputs the key operation signals.
Drives the LCD back light.
Controls the ICU SCN PWB, ICU IMG PWB, and CCD PWB. Converts digital
image data into video signals and sends them to the scanner (writing) unit.
Performs correction of images outputted from the CCD.
Performs image processes such as area separation, color correction, black
generation, gamma correction, and filter process.
Recognizes the bank note patterns.
Detects the original size.
Outputs light to detect the original size.
Outputs the CCD PWB paper power.
Scanner motor control PWB.
Controls the image process section.
Generates the high voltage for main charger and the developing bias voltage.
Interfaces the main charger power.
Controls (drives) the OPC drum motor. (AR-C150/C250/C160/C270)
Signals are interfaced. (AR-C160/C270)
Controls the scanner lamp
Detects humidity in the machine.
Controls the engine section.
Relays the signal of CCD PWB and ICU-SCN PWB. (AR-C150/C250)
Generates the clock at the time of monochrome print operation and relays the
signal of CCD PWB and ICU-SCN PWB. (AR-C160/C270)
Controls the paper tray lift unit.
Discharges electric charges on the OPC drum.
Equipped with No. 1/2 paper tray paper exit detectors and the right upper door
open/close detector.
Equipped with No. 3/4 paper tray paper exit detectors and the right lower door
open/close detector.
Interfaces signals between the developing unit, OPC drum unit, the high voltage
PWB, and the PCU PWB.
Interfaces the heater lamp drive control, sensor, detector signals.
Generates the transfer voltage.
Generates the voltage used by the other units than the operation unit.
Generates the voltage for the operation unit (AR-C150/C250)
Controls powers of 24V, 5V and 3.3V in the sleep mode, the preheat mode, and
the normal mode. (AR-C160/C270)
Controls the primary side power (AC power).
Converts original images (light) into electrical signals.
