Paper Feed - Tray 2
1. 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).
2. No Paper Sensor:
Detects presence or absence of print media in the tray based
on the position of the Actuator.
3. Paper Pick 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 pick-up 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.
4. Turn Clutch Assembly
:
Transfers the drive energy from the main drive
assembly to the roll turn assembly.
5. Paper Size Switch: Detects print media size and installation of the paper tray.
6. Gear Feed: See Paper Pick Rollers.
7. Spring Feed: See Paper Pick Rollers.
