3.6.6 Toner cleaning
<Flow of toner cleaning>
(1) Toner remaining on the exposure drum which has not completely been transferred on to
the paper is pulled onto the drum cleaner with a lower potential and the drum is cleaned.
(2) After the above step, the potential of the drum cleaner is raised during printing, and such
attracted toner is returned to the exposure drum again. The returned toner is attracted to
the belt unit by lowering the potential of the transfer roller.
(3) The toner attracted to the belt unit is collected by the belt cleaner below the unit, and
stored in the waste toner box.

Memo:
When the toner returns to the exposure drum from the drum cleaner, the develop roller is
separated from the exposure drum to prevent color mixture.
