Job Offset - Panasonic DP-3510 Service Manual

11.1.2.2.4. Job Offset

1. Outline
In the job offset mode, sort jobs and entire copy groups are shifted to the front for delivery to the tray,
and other copies are delivered to the tray without a shift.
The copies are shifted by the alignment plate. The alignment plate is checked by the Alignment Home
Position Sensor (PI6) to find out whether it is at the home position.
The Finisher Controller PCB drives the Alignment Plate Motor (M3) at power-on to return the Alignment
Plate to its home position.
The Finisher Controller PCB stops the Delivery Motor (M2) when the trailing edge of the copy has
moved past the Feed Roller 2. Then, the Finisher Controller PCB rotates the Delivery Motor counter-
clockwise, and drives the Swing Motor (M7). As a result, the drive of the Delivery Motor is transmitted
to the Swing Guide to move up the guide. When the Swing Guide Open Detection Sensor (PI18)
detects the Swing Guide, the Delivery Motor stops, and the Swing Guide is held at the up position.
When the Swing Guide has moved up, the Feed Belts attached to the Feed Roller 2 move the copy to
the Stapling Tray. The presence of paper on the Stapling Tray is monitored by the Stapling Tray Paper
Sensor (PI4). (The first sheet is fed to the Stapling Tray while the Swing Guide is moving up.)
The Finisher Controller PCB drives the Alignment Motor (M3) in advance, and keeps the Alignment
Plate poised 10mm behind the trailing edge of a sheet. Whenever one sheet is moved to the Stapling
Tray, each sheet is aligned, and when the fifth or last sheet in a sort job/group is fed to the Stapling
Tray, the Guide Plate Retaining Solenoid (SL6) moves the Guide Plate away and under the Stapling
Tray. From then on, the Alignment Motor shifts the sheets to the front by 30 mm.
When the copy has been shifted, the Finisher Controller PCB rotates the Alignment Motor counter-
clockwise to move the Alignment Plate to a point 10 mm behind the trailing edge of the sheet.
This alignment operation is repeated until alignment of the fifth or last sheet in a sort job is completed.
At this time, the Swing Guide is moved down and is closed, and the Delivery Motor rotates clockwise to
deliver the sheet.
