2.3.1.2 Electrical configuration
Electrical circuit configuration
Electrical control of the MFP is executed by the main controller circuit PCB.
The ASIC of the main controller circuit PCB interpret the input signals that are supplied from
sensors and the signals that are supplied from the externally connected equipment.
The ASIC output thesignals that drive the DC load devices such as motor, solenoid and
clutch in accordance with the specified timings.
The ADF relay circuit PCB do not contain the memory area.
The data such as service mode data is stored in the main controller circuit PCB.
