6.3.1 Basic Sequence of Operation
0020-4093
The basic sequence of operation of this machine is explained below.
For more details, refer to the explanation of various types of bias control.
- At power-on (when the door is opened/closed)
The main motor starts rotating after completion of the error check.
To prevent fogging of the drum, the developing DC bias voltage is held higher than usual during application of the developing AC bias voltage.
F-6-3
- During printing
To prevent fogging of the drum, the developing DC bias is held higher than usual except during image formation.
To prevent the toner remaining on the photosensitive drum from sticking to the transfer charging roller, the transfer roller bias which is lower than that applied
during printing the is applied at the prescribed timing.
