2. Description
1. Paper dust and waste toner may cause the CL brush roller to become clogged which in
turn may cause a cleaning problem or the drum to wear unevenly.
2. Waste toner may adhere to the waste toner transport screw, which will decrease the
performance of the transport screw.
The above issues may lead to black streaks to appear on the copies. If these copy quality
issues occur replace the CL brush roller and the waste toner transport screw at the same
time.
3. Description
1. The bristles of the CL brush roller have been made thicker and the density of the
bristles has been lowered.
2. Changing from a resin waste toner transport to a metal type has been implemented at
the same time.
Improvement to clear waste toner from the process
unit.
