2.5.8.1 Part Names and Functions

FAN MAIN

Prevents overheating inside the printer by exhausting/inhaling the ambient air.

SWITCH POWER

Tuns on/off the AC power supply to the printer.

LVPS (Low Voltage Power Supply)

There are two types of the LVPS; 100/120 V and 230 V.

The LVPS not only provides AC voltage to the FUSER UNIT heater from the
power source, but generates/supplies stable low DC voltage that is required for
parts such as the logic circuit. The LVPS consists of the power circuit and the
control circuit for the FUSER UNIT heater.

PWBA MCU

Controls the print operations by communicating with the printer controller and
analyzing the information from the sensors and switches.

The main functions are as follows.

Communicates with the printer controller

Receives information from the sensors and the switches

Controls motors in DRIVE ASSY MAIN and DRIVE ASSY PH

Allocates the low DC voltage output from the LVPS among each component

Controls the ROS ASSY

HVPS (High Voltage Power Supply)

Supplies high voltage to TRANSFER UNIT and IMAGING CARTRIDGE so that
the following parts can perform charging, developing, and initial transfer.

PWBA EEPROM

Stores information specific to each printer.

BOARD ASSY, MAIN

Print controller.

BOARD ASSY, MAIN that is connected to PWBA MCU controls the whole system.

SENSOR HUM

Detects temperature and humidity inside the printer and converts the values to
voltage value.

CONTROL PANEL

Shows the printer conditions with LCD and LEDs, and operates the printer with
the buttons.

HARNESS ASSY INTERLOCK

Interrupts the +24VDC power supply to HVPS and motors immediately when
Front Cover is opened.
