Theory of Operation 2-41
Tray 2 Paper Pick Assembly
â– Temperature/Humidity Sensor
Detects temperature and humidity inside the printer to adjust the charge voltage
(the voltage supplied to the transfer roller and the developing bias).
â– No Paper Sensor
Detects presence or absence of print media in the tray based on the position of the
Actuator.
â– Feed Rollers
When the Feed Solenoid energizes, the Spring Feed force engages the Gear Feed
and the Gear Idler Feed to turn and feed the paper from the paper tray. This
activates the Paper Pick Assembly. After completion of one turn, determined by a
cutout in the Gear Feed, the Gear Feed and the Gear Idler Feed are disengaged
stopping the paper Retard Feed Roller. This allows one sheet to be fed at a time.
â– Turn Clutch
Transfers the drive energy from the Main Drive Motor to the Turn Roller.
â– Paper Size Switches
Detects print media size using the position of the side and rear guides, and
presence of the paper tray.
