Tray Initialization - Ricoh D025 Service Manual

Tray Operation
The motor starts, and just as the pawls start to push the stack onto the tray the edge
depressor solenoid switches on and retracts the edge depressors
The stack is on the tray. The solenoid switches off, and the depressors move
forward and press down lightly on the trailing edge of the stack.
If the paper height sensor is OFF, go to
If the paper height sensor is ON, go to
The tray lift motor switches on, lowers the tray, and then stops when the paper
height sensor goes ON.
The tray lift motor reverses for 100 ms to raise the tray to the start position.
The pawls move to their home positions and stop.
The sequence starts again with the next finished stack,.

2.6.3 TRAY INITIALIZATION

The following sequence occurs at power on depending on the states of the paper height
sensor and tray full sensor:
The edge depressor solenoid switches from ON to OFF.
If paper height sensor ON, then go to
Paper height sensor OFF.
If the tray full sensor is ON and the paper height sensor is OFF, this signals
that the output tray is full. Removing the paper from the tray will switch the
paper height sensor ON. The tray lift motor switches on, lowers the tray,
reverses for briefly to raise the tray to the start position, then switches OFF.
The tray lift motor continues to lift the tray until the paper height sensor goes OFF,
continues to run 100 ms, and stops.
