A. Let the unit staple 5 sheets of A4 or letter paper and check the
bundle of the sheets for deviation in directions A).
B. When the deviation in directions A) is are within 1 mm, there is no
need to adjust the jogger F/R.
C. When the deviation exceeds 1 mm, adjust the jogger F/R accord-
ing to the simulation 3-6: Adjusting Finisher Jogger Position.

1) Adjust the value with the numeric keypad.
2) The joggers in the finisher are operated by pressing the [EXE-
CUTE] key. The [EXECUTE] key is displayed in reverse video
during loading operation. When the [EXECUTE] key in this state
is pressed, loading operation can be canceled.

2. Paper entry gate solenoid
[Adjustment and precaution in setting]
1) Insert the paper entry gate solenoid pin A into the hole B on the
paper feed gate arm and secure with the screw 4). In this step,
align the F flame edge with the position aligning stamp as shown
in the enlargement above.
align the F flame edge with the position aligning stamp as shown
