2) If you are using A4 paper for the adjust-
ment, press SW1 on the finisher controller
PCB. If you are using LT paper for the ad-
justment, press SW2 on the finisher con-

the alignment guide and the guide plate,
butting them against the stoppers.
4) Press SW1 or SW2 on the finisher control-
ler PCB and butt the alignment guide
against the sheets.
• Each press of SW1 shifts the alignment
guide towards the front in 0.35 mm incre-
ments.
• Each press of SW2 shifts the alignment
guide towards the rear in 0.35 mm incre-
ments.
5) Press SW1 and SW2 simultaneously to
store the adjustment value.
6) Exiting the adjustment mode
Shift all bits on the DIP_SW OFF and turn
