The charge roller, transfer roller and cleaning roller are cleaned in the following cases:
• In warming up at power-on time
• In warming up after the cover is opened and closed
• When the number of accumulated sheets is 10 or more and the printout operation ends
Changes in bias voltage applied to each roller move adhesive toner from the roller to the
image drum and return it to the developer.
