Exposure
Pre-exposure control Flash the pre-exposure LED on the photosensitive drum
surface.
Primary Charging
Primary charging bias control Apply a positive bias to the primary charging wire and primary
grid plate.
Primary charging wire
cleaning control
Perform cleaning of the cleaning wire.
Development
Developing bias control Apply a negative charge to the developing cylinder to attach
the toner on the developing cylinder to the photosensitive drum
surface.
Dust-collecting bias control Collect stray toner to prevent stray toner from attaching to
photosensitive drum during development.
Transfer
Pre-primary transfer charging
bias control
Charge toner to an even negative potential to increase
stabilization of transfer operation.
Pre-primary transfer charging
wire cleaning control
Perform cleaning of the pre-transfer charging wire to prevent a
charging failure caused bay dirt on the primary charging wire.
Primary transfer bias control Apply a positive charge to the primary transfer roller to transfer
the toner on the photosensitive drum to the ITB.
Secondary transfer bias
control
Apply a negative charge to the secondary transfer internal
roller to transfer the toner on the ITB to the paper.
Secondary transfer static
eliminator bias control
Apply a negative bias to the secondary transfer static
eliminator.
ITB cleaning control Remove the residual toner remained on the ITB to prevent an
image failure caused by dirt on the ITB.
ITB displacement correction
control
Correct the displacement of ITB to prevent.
Secondary transfer external
roller cleaning control
Remove the residual toner remained on the secondary transfer
external roller to prevent an image failure caused by dirt on the
secondary transfer external roller.
Secondary transfer external
roller engage/disengage
control
Engage and disengage the Secondary transfer external roller
to the ITB.
Drum Cleaning
Drum cleaning control Remove the residual toner remained on the photosensitive
drum.
Drum cleaning pre-exposure Flash the pre-exposure LED to remove drum memory on the
photosensitive drum surface.
