3.9.1 Major functions
- FAN
Dissipates heat out of the printer to prevent the printer from overheating.
- SWITCH
The SWITCH turns ON/OFF the AC power supply of the printer.
- Low Voltage Power Supply (LVPS)
The LVPS is provided in two types, 120V and 240V.
Supplies AC power from the power source to the FUSER heater and generates and supplies stable
low voltage DC power used for the logic circuit, etc.
LVPS contains control circuit for the heater of the FUSER, in addition to the power circuit.
- Machine Control Unit (MCU)
Controls printing operation based on the communication with the print controller and information
from the sensor/switch.
Major functions are as follows:
• Communication with the ESS.
• Receive of information from the sensors or switches.
• Control of Motor in DRIVE ASSY MAIN and DRIVE ASSY SUB.
• Distributing low voltage DC power output from LVPS to each component
• Control of ROS
- High Voltage Power Supply (HVPS)
Supplies high voltage to the following parts in the Transfer Belt and Developer to perform charging,
development, and primary transfer.
• BCR
• BTR
• Developer
- PWBA EEPROM
Information unique to the printer is stored.
- Electronic Sub System (ESS)
The ESS connected to the MCU controls the entire system (Diagnostic, Interface and Image
processing).
- HUMIDITY SENSOR
HUMIDITY SENSOR reads the temperature/humidity within the printer and converts the values to
voltage values.
- OPERATOR PANEL
OPERATOR PANEL displays the state of the printer using LED.
- INTERLOCK SWITCH
INTERLOCK SWITCH is a switch that cuts the +24VDC power supply to the HVPS or Motor, etc.
upon the opening of the Front Cover.
