Phaser 6300/6350/6360 Color Laser Printer Service Manual 2-49
Theory of Operation
Electrical
■ Circuit Board HCF (OPTFDR 2)
Controls the paper pickup operation of each tray based on communication
with the Engine Control Board and information from the sensors and
switches.
Major Functions:
■ Communicates with the Engine Control Board.
■ Receives information transmitted from the sensors and switches.
■ Controls the Feeder Drive Assembly.
■ Controls the paper pick process.
■ Distributes the DC voltage from the printer’s LVPS to each
component.
■ Drive Assembly
Drives the Pickup Assemblies.
■ Low Paper Sensors
The actuator lowers as print media is used in the tray. When the actuator
blocks the sensor, low paper status is indicated.
