1. HCF Feeder Circuit Board:
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 power supplied from the print engine to each
component.
2. Feeder Drive Assembly:
3. Low Paper Sensor:
When the actuator lowers to a pre-determined postion, it blocks the sensor beam
to trigger a low paper status. The actuator position can be seen from the front of
the HCF allowing confirmation of the print media quantity.
Theory of Operation
3(T4)
Controls the paper pick-up operation of each tray
Supplies the drive to the Tray 3 and 4.
The actuator lowers as print media is used in the tray.
