C. Job Offset
In job offset, the adjustment plate shifts the very first page of the job to one side but the rest of
the pages remain unshifted. Whether or not the adjustment plate is in the home position is
detected by the adjustment plate home position sensor (PI6).
When the power of the stapler stacker is turned ON, the stapler stacker driver rotates the
adjustment plate motor (M3) in order to return the adjustment plate to the home position. If the
adjustment plate is in the home position, it remains in the position and stands by. In the case
that the paper size is other than A3 or A4-horizontal, as the shifting distance of the adjustment
plate is long, the stapler stacker driver shifts the adjustment plate to the standby position
(Note
1) .
The stapler stacker driver stops the delivery motor (M2) when the trailing edge of the first page
passes the delivery roller 1 by 20mm. 0.2 seconds later, M2 is rotated counterclockwise, which
shifts the M2 gear to the swing guide drive side. As a result, M2 rotates the swing guide drive
and the swing guide is lifted. The swing guide stops when it is detected by the swing guide close
sensor (PI18).
When the swing guide is lifed, the paper is pulled back to the staple tray by the rubber rollers
on the delivery roller 1. The paper placed in the staple tray is detected by the staple tray paper
sensor (PI4).
0.2 sec. after PI4 detects the paper, the stapler stacker driver drives the adjustment plate
motor (M3) and shifts the paper by 30mm. Depending on the paper size, the left edge may pre-
vent the paper from being shifted. In such a case, the stapler stacker driver turns ON the ref-
erence plate withdrawal solenoid (SL6) and withdraws the left edge reference plate before shift-
ing the paper.
After shifting the paper, the stapler stacker driver rotates M3 counterclockwise to shift the
adjustment plate to the reset position (Note 2) .
The stapler stacker driver rotates M2 counterclockwise to lower the swing guide. When the
swing guide turns ON the swing guide close detection switch (MS2), M2 starts rotating clockwise
which rotates the delivery roller 2. Paper is delivered to the tray by the delivery roller 2. Second
page and thereafter in each job are delivered to the tray without being shifted.
When the shifted amount of the adjustment plate during the home position detection exceeds
the prescribed maximum shifted amount, the stapler stacker driver judges it as motor trouble
and informs it to the option controller.
Notes: 1. The standby position is 10mm off to the outside from the center of the width of the
paper.
2. The reset position is 4mm off to the outside from the home position.
