Cause

Since a mixture of the toner and paper dust accumulates on the tip of the hot roller
stripper, a gap develops between the stripper and hot roller surface. Under this condition,
the copied paper is not separated by the hot roller stripper, leading to jams in the fusing
unit (the paper gets caught on the tip of the hot roller stripper).

Contents of Change

To reduce the amount of toner and paper dust attracted to the hot roller stripper, the
material of the stripper will be changed from PPS to PEK.
To increase the contact pressure between hot roller and stripper, the tension of the hot
roller stripper spring will be changed from 150 mN to 300 mN.

Cause:

Jams in the fusing unit area (C-jams) are cleared by opening and closing either the front or
right door, even when the jammed paper has not been removed. This in turn causes jams
to reoccur when the next print job is done.

Countermeasure

The following will prevent C-jams from being cleared by opening and closing the front
door:

1. The front door push switch, switch bracket, and tapping screw have been deleted.

This switch was then added to the right door switch assembly, making a total of 4.

2. The length of the fastening screw for the right door microswitch has been increased.

3. The length of the front-upper DC harness has been increased and the harness has

been rerouted to the right door microswitch assembly.

To ensure proper grounding, the shape of the anti-static brush has been changed and
grounding plates for the exit and paper feed rollers have been added. Please refer to the
illustration below. This modification reduces the occurrence of paper jams caused by
static electricity buildup.
