6.5.24 FIBROUS DEPOSITS OCCUR ON THE BACK SIDES OF
PAPER AT THE LEADING EDGES
Deposits resembling fibers can occur at the leading edge on the back side of paper.
Cause
1. When the fusing entrance guide plate [A] is raised to counter paper wrinkling during fusion
in this machine, this can severely abrade the back side of paper at the leading edge.
2. Paper dust from paper collects on the edge of the fusing entrance guide plate, causing
toner and other matter scraped from the guide plate to form tendrils of fibrous deposits [B].
3. The build-up of these fibrous deposits collects on the back side of the paper.
[A] Fusing entrance guide plate
[B] Fibrous deposits
[C] Hot roller
Action
Do the following cleaning procedures.
1.
Remove the fusing unit.
2.
Remove fusing unit top cover.
(You can do this procedure without cover removal, but this procedure makes it easier to
see the fusing entrance guide.)
