Removing The Separation Roller; Adjusting The Tension Of The Separation Roller - Canon ImageRunner 600 Service Manual

CHAPTER 7 PICK-UP/FEEDING SYSTEM
6.

Removing the Separation Roller

1) Remove the two mounting screws [1], and
detach the separation roller support plate
[2].
2) Remove the joint [3], and detach the sepa-
ration roller [4].
Caution 1:
When removing the separation roller,
pay attention to the bushing at the front.
It will slip off.
Caution 2:
Initially, the urethane sponge of the part
is pink, and changes over time (acceler-
ated if exposed to light).
Its tone will change from pink to orange
and to yellow; it is a general characteris-
tic of urethane sponge, and no physical
deterioration (in performance) exists be-
cause of changes in color, and the part is
not identified by color.
7. Adjusting the Tension of the
Separation Roller
If double feeding or pickup failure occurs,
adjust the position of the pressure spring used
for the separation roller.
• If double feeding occurs, move the spring in
the direction of A.
• If pickup failure occurs, move the spring in
the direction of B.
