(7) Cleaning
When the transfer is completed, the residual toner left on the image drum is attracted to
the cleaning roller temporarily by static electricity, and the image drum surface is cleaned.
(8) Cleaning of rollers
The charge, transfer and cleaning rollers are cleaned for the following cases:
• Warning up when the power is turned on.
• Warning up after the opening and closing of the cover.
• When the number of sheets accumulated reaches 10 or more, and the printout operation
ends.
Changes in bias voltage applied to each roller move attaching toner off the roller to the
image drum and return it to the developer.
