4. Insert one sheet of the paper (P/N 65AA-9910)
between the multi feed detection board /1 and
/2 (200 to 300 g/m
Be sure the paper does not trail down.
Note
• If the paper trails down, the angle of paper
insertion is different from that of paper pas-
sage, thus making it impossible to make an
accurate adjustment.
5. Connect the tester (voltmeter) to the following
positions of the ADUDB1.
+terminal: test pin No. TP60 (white) [1]
- terminal: test pin No. TP57 (green) [2]
Range: DC 20 V
[1]
Note
• Because the ADU is powered, do not drop
any metal material on the board, or do not
connect the tester pin to an irrelevant ter-
minal.
It may cause the board to short circuit and
be damaged.

previous adjustment.

Repeat the steps 8 to 10 until detection error is
resolved.

E. Cleaning blade transportation lock
This separates the cleaning blade from the drum,
thus preventing any damage on the cleaning blade
while moving the machine or during a long-term stor-
age.
Use this when packing the machine while moving an
installation location.
NOTE
• While conducting this mode, the blade is
automatically replaced. In case the first
cleaning blade was used before packing, be
sure to perform a spring charge for the auto
blade replacement as you reinstall the
machine.
