Lower Paper Cassette
A maximum of 500 sheets can be loaded in the optional 500-sheet lower paper cassette. The paper
size, however, must be a size that the casette is capable of handling. (The lower paper cassette unit
can hold letter or A4 paper.)
The driving force for paper feeding and transport is from the transmission gear. All electrical
controls are performed on the printer side through the coupling connector.

2.1.1.2 Drum Charge

Drum charge is the process of charging the PC drum with static electricity before laser exposure.
This printer uses a brush charge method, rather than the corona charge method, to charge the
drum. In the brush charge method, there is no generation of ozone as a result of corona discharge.
This method also allows the drum to be charged at a low voltage, because a direct electric load is
applied to the PC drum.
