Description
From when the main power is turned on until the fixing roller temperature reaches a specific level, the potential control of
the photosensitive drum ends, and as much as 60 sec passes from power-on.
The machine executes potential control of the photosensitive drum. For each mode (i.e., copier, printer), it executes VD
control (to adjust the primary discharge current) and VL control (to adjust the laser output) and determines Vdc (developing
bias).
The machine is in a state in which it is ready to accept a copy/print request signal.
