The folding position is adjusted by chang-

ing the settings of bits 6 through 8 of DIPSW1
on the saddle stitch controller PCB to match the
stitching position (i.e., adjusting the distance over
which the paper positioning plate is moved to
the folding position from the stitching position.)

If you have replaced the saddle stitch con-

troller PCB, be sure to set the new DIPSW1 so
that the settings will be the same as those on the
old DIPSW1. If, for any reason, you must
change the following position, perform the fol-
lowing steps:
1) Remove the PCB cover, and set bits 1

through 4 of DIPSW1 on the saddle stitch
controller PCB as indicated.

Do not change bits 5 through 8.

2) Remove the rear cover of the saddle stitch

unit, and tape the actuator of the inlet cover
open sensor (PI9S) and the inlet cover open
detection switch (MS1S) of the saddle stitch
unit in place.

3) Before inserting the paper, mark the top of

the paper (you will be using two sheets of
A3 or LD paper).

4) Press SW2 on the saddle stitch controller

PCB so that the feed motor (M1S) starts to
rotate. (Press SW2 three seconds or more if
LD paper is used).

5) Open the inlet cover, and insert two sheets

of paper (push them in by hand until the
leading edge of the sheets butts against the
paper positioning plate).

6) Close the inlet door while holding it down

with your hand.

7) Press SW2 on the saddle stitch controller

PCB.

• The saddle stitch unit will “stitch” the

sheets, and fold and deliver the stack auto-
matically.
