7) Press SW2 and SW3 simultaneously.
• The press will open the swing guide, and
cause the feed belt to rotate. Placement of
one sheet of A4/LTR paper will cause the
finisher to start stapling operation.
8) Check the stapling position. If good, shift
all bits of SW1 to OFF*. If re-adjustments
are necessary, go back to step 6).
*If you are disabling the manual feed tray
height control mode, set bit 2 on SW1 to
ON.
Caution:
The settings held by the finisher controller
are changed as soon as SW2 or SW3 is
pressed. As such, to recover the previous
settings after the press, you must press the
other of the two switches as many times as
you pressed previously.
4. Disabling Manual Feed Tray Height
Control Mode
When such large-size sheets as SM-1 or
GNT-80 are stacked continuously during
manual feed pick-up operation, the trailing edge
of a sheet can become stuck on the delivery
roller assembly, causing the subsequent sheets
to jam. This is because manual feed pick-up
operation is executed in manual feed tray height
control mode to control the height of the tray.
For users who tend to make use of large-
size sheets often, the mode may be disabled as
follows:
a. Disabling the Mode
Shift bit 2 of SW1 on the finisher control-
ler PCB to ON.

The new switch setting will use the same
tray height control for both manual pick-up and
cassette pick-up. The stacking volume, how-
ever, will be 200 sheets or less of 80 g/m
per (stack partly consisting of transparencies).

Caution:
Note that a single setting will not fully

mode simultaneously. Be sure to consult with
the user about paper types of choice before
deciding whether to change the switch
settings.

1. Adjusting the Folding Position
The folding position is adjusted by chang-
ing the settings of bits 6 through 8 of DIPSW1
on the saddle stitcher controller PCB so as to
match with the stitching position (i.e., adjust-
ing the distance over which the paper position-
ing plate is moved to the folding position from
the stitching position).
