Make the following adjustments if the copy paper picked up from the multifeeder moves askew
or wrinkles are noted on the leading edge of the copy paper; the adjustments are made by changing
the degree of arching of the copy paper between the multifeeder pick-up roller and the registration
roller.
1) Set 50 sheets of A4 paper (80 g/m

) on the multifeeder tray.
2) Press the PAPER SELECT key on the control panel to select the multifeeder.
3) Press the COPY START key.
4) Check that the leading edge of the copy paper butts against registration roller and arches; at the
time, turn the copier OFF.
5) Measure the distance between A (trailing edge of the second sheet) and B (trailing edge of the
first sheet).

6) Turn the copier ON, and select C4 in the service mode.
7) Enter a setting so that the measurement between A and B (step 5) is between 70 and 75 mm.
Note:
A higher setting increases the measurement, i.e., the multifeeder clutch OFF timing is de-
layed (in units of 0.25 mm).
