7) Based on the result of the check, press
SW105 or SW106 on the finisher control-

• A single press on SW105 will move the
stapling position to the front by about 0.35
mm. The indication of LED101, on the
other hand, will increment by '1' in the
positive (+) direction.
• A single press on SW106 will move the
stapling position to the rear by about 0.35
mm. The indication of LED101, on the
other hand, will increment by '1' in the
negative '0' direction.
8) Insert a stack of several A4 or LTR sheets
into the processing tray as in step 3).
9) Press SW104 once so that you can enter a
new adjustment value.
• Stapling will occur automatically so that
you can check the stapling position.
LED101 will indicate '0'.
10) Turn off the power.
