Drum-to-Belt Transfer

Among the following two print modes, the correct mode is selected automatically according to the print data sent from the printer controller.

• BW mode: Job contains only black data.

• FC mode: Job contains color data.

By applying a positive (+) bias (transfer current) to the image transfer roller, negatively charged toner (-) on the drum is attracted to the ITB that positions between the roller and the belt. Any remaining toner on the drum is cleaned by the drum cleaning unit.
