SETTING ADJUSTMENT
6 - 84
6.7.2 Separation roller pressure force adjustment
In some cases the life of the separation roller may be shortened or paper jams and multiple feeding
(EB50) may occur regardless of the operation frequency of the equipment. This comes from the weight
or edge status of paper used and the amount of paper dust.
Generally paper jams and multiple feeding often occur as the life end of the roller approaches.
However, if they often occur even though its life has not yet reached its replacement timing, or if the life
end comes much earlier than the scheduled replacement timing, the jams and multiple feeding can be
suppressed by adjusting the pressure force of the separation roller.
In this method, however, when the roller life becomes longer, jams and multiple feeding may occur
frequently, and when the jams and multiple feeding are suppressed, the roller life may become shorter.
Therefore, perform this adjustment while checking the status carefully, and if necessary, give a
sufficient explanation to users.
[ 1 ] Adjustment procedure of the drawer feeding unit
(1) Take off the drawer feeding unit.
P. 4-55"4.5.14 Drawer feeding unit"
(2) Remove 1 screw, and then screw it
temporarily to an oblong hole located next to
it.
Notes:
Make a mark for the installation position of
the bracket in advance.

(3) Move the bracket.
Move to the direction A: The roller life will
become longer (but multiple feeding may
occur frequently).
Move to the direction B: Multiple feeding will
be suppressed (but the roller life may
become shorter).
Notes:
The recommended moving distance of the
bracket is within 2 or 3 scale marks.
