Delivery - Xerox Paser 7400 Service Manual

Delivery

The Finisher Unit includes a Delivery Tray, and the Saddle Unit includes a Bind Tray.
The Bind Tray is a fixed unit where all folded paper stacks are delivered. The Bind
Tray includes a Bind Tray Sensor to detect the presence of paper. The delivery tray in
the finisher unit moves up and down using a Lift Motor.
The Paper Surface Sensor detects the home position of the delivery tray. If paper is
already stacked on the delivery tray, the home position is sensed on the top surface of
the stacked paper. When the paper coming from the processing tray stacks on the
Delivery Tray, the Lift Motor receives a specified number of pulses, which causes the
Delivery Tray to lower to the home position. The Lift Motor Clock Sensor detects
when the tray reaches the home (lowest) position.
The Shift Upper Limit Sensor detects the upper limit of the Delivery Tray. In an upper
limit condition, the Finisher Controller Board stops sending commands that lift the
Lift Motor. Conversely, the Shift Lower Limit Sensor detects the lower limit of the
Delivery Tray. In a lower limit condition, the controller board stops the Lift Motor.
Delivery after Stapling
When stapling completes, the Finisher Controller Board drives the Delivery Motor in
the forward direction to feed the paper stack. When the Delivery Belt Home Position
Sensor reaches the OFF position, the delivery stack is full.
The Slide Motor is then driven to return the Stapler Unit back to the standby position,
which initiates the Delivery Motor drive. Then, the paper stack is delivered to the
tray.
