Theory of Operation 2-57
Electrical
■ Circuit Board LTA (OPTFDR 1)
Controls the paper pickup operation 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 Paper Pick Assembly.
■ 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.
