Chapter 10 Machine Overview
10.11.3 Electrical
10.11.3.1 Electrical
- FAN (PL8.2.8)
Dissipates heat out of the printer to prevent the printer from overheating.
- SWITCH (HARN ASSY INLET AIO: PL8.3.7)
The SWITCH turns ON/OFF the AC power supply of the printer.
- Low Voltage Power Supply (PWBA LVPS: PL8.2.12)
The LVPS is provided in two types, 120V and 240V.
Supplies AC power from the power source to the FUSING UNIT 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 FUSING UNIT, in addition to the power circuit.
- Machine Control Unit (PWBA MCU: PL8.3.6)
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 ASSY
- High Voltage Power Supply (PWBA HVPS: PL4.1.19)
Supplies high voltage to the following parts in the TRANSFER ASSY and Developer to perform
charging, development, and primary transfer.
- BCR
- BTR
- Developer
- PWBA EEPROM (PL8.3.4)
Information unique to the printer is stored.
- Electronic Sub System (PWBA ESS AIO: PL8.1.2)
The ESS connected to the MCU controls the entire system (Diagnostic, Interface and Image
processing).
- HUMIDITY SENSOR (SENSOR HUM: PL8.1.10)
HUMIDITY SENSOR reads the temperature/humidity within the printer and converts the values to
voltage values.
- OPERATOR PANEL (CONSOLE ASSY PANEL AIO: PL1.2.3)
OPERATOR PANEL displays the state of the printer using LED.
