Engine

This board controls the operation of the operation panel keys, LCD and LEDs.

Operation Panel, NFC (MF Models)

This board controls all of the machine, input/output, drivers and input/output connections and the handshake with the Controller.

EGB (MF Models)

This board controls the memory, all applications and all peripheral devices.

Controller Board (MF Models)

This sensor detects the relative temperature and humidity around the machine.

Temperature/Humidity Sensor

This board supplies the charge to the image transfer roller and high voltage for the charge roller, transfer roller and the development roller.

High Voltage Power Supply Board

This board relays the ID chip data of each AIO from/to the EGB.

ID Chip Board

This supplies DC power for the EGB, fusing unit and interlock switches.

PSU

This motor exhausts air around the fusing unit.

Fusing Fan Motor

This motor exhausts air around the laser optics housing unit.

LSU Fan Motor

These switches turn off DC power when the front cover or top cover is open.

Interlock Switches

This solenoid is connected to the stripper pawl, and it detaches the stripper pawl from the hot roller unless it is necessary to contact.

Paper Exit Sensor

This sensor detects a paper jam in the fusing unit, paper exit path and duplex path.

Paper Exit Sensor

3

Paper End Sensor

This sensor detects paper end and whether the tray is set.

Paper End Sensor

4

Registration Sensor

This sensor detects a paper jam at the paper feed, by-pass feed and registration roller, and also determines the paper size based on the sensor on-off time.

Registration Sensor

This sensor detects whether the waste toner bottle is full.

Waste Toner Overflow Sensor

This sensor detects whether the waste toner bottle is set.

Waste Toner Bottle Set Sensor

This sensor detects whether the image transfer belt is in contact with the color OPCs (C, M, Y).
