Additional details on the Drum Cartridge function appears in the “Summary of the
Printing Process” on page 2-2.
Transfer Roller
The Transfer Roller is driven by being held in direct contact with the Drum Cartridge.
When paper moves between the Transfer Roller and Drum, the Transfer Roller
applies a positive charge to the rear surface of the paper. The negatively charged,
developed image on the drum is attracted by the positive charge on the rear surface of
the paper. Thus, the developed image is transferred from the surface of the drum to the
surface of the paper. The Detack Saw, located adjacent to the Transfer Roller, helps to
separate the paper from the drum surface.
Magnetic Roller A thin layer of developer and toner adheres to the surface of this
roller, which transports the toner to the Drum surface.
Charging and Metering
(CM) Blade
The CM Blade spreads a thin, even layer of developer and toner
over the Magnet Roller, and applies negative charges to the
toner triboelectrically.
Cleaning Blade The Cleaning Blade removes toner remaining on the Drum.
