Stack Delivery Operation; Job Offset Sequence - Panasonic DP-C305 Service Manual

4. Stack Delivery Operation

Stack delivery takes place when 10 sheets of large-size paper, or 30 sheets of small-size paper (A5-
and STMT-sizes: 10 sheets) have been stacked on the Processing Tray with them offset in either
direction.
The Paddle Motor rotates, and the Swing Guide descends to hold the paper stack between the Upper
and Lower Stack Delivery Rollers. The Delivery Motor rotates in the forward direction to rotate the
Delivery Rollers, feeding the paper stack in the delivery direction. The Delivery Belt Home Position
Sensor is turned OFF. The Delivery Motor is driven a specified number of pulses, causing the Swing
Guide to ascend. Next, the Paper Delivery Motor is driven. Next, the Delivery Motor is driven to deliver
the paper stack with the nails of the Delivery Belt that rotates in sync with the Stack Delivery Rollers.
