Lower Paper Cassette
A
of
250 sheets can be loaded in the 250-sheet lower paper cassette (option). The cassette
must capable of handling the paper size, however. (The lower paper cassette unit can hold
letter, A4, or
paper.)
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.
