Previous
To enable printing in all five toner colors as well as printing using only special color, the mechanism to contact/separate the ITB and ITB rollers was modified in the drum-to-belt transfer process for the machine. Among the following four print modes, the correct mode is selected according to the print data sent from the printer controller.
BW mode: Job contains only black data.
FC mode: Job contains color data.
FCS mode: Job contains color and special color data.
S mode: Job contains only special color data.
1. OPC drum
5. Image transfer roller
6. Intermediary transfer belt(ITB)
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.
