• IEEE1284 (Centronics)
• IEEE802.11b (Wireless LAN)
• Gigabit Ethernet Board
Mother Board
Interfaces the BICU and Controller. The operation panel connects directly to the Mother Board.
Operation Panel
Controls the LCD user interface and button controls.
PSU (Power Supply Unit)
Provides dc power to the printer system and ac power to the fusing lamp.
HVPS (High Voltage Power Supply)
Supplies high voltage to the drum charge roller, development roller, and transfer belt.
IOB (Input/Output Board)
Controls the mechanical parts of the printer, all the paper feed mechanisms, and fusing lamp power.
Specifically, the IOB controls:
• All main drive sensors, motors, and solenoids.
• PWM (Pulse Width Modulation) of the HVPS.
• Serial interfaces of all peripherals.
• Fusing lamp operation
