Interval Description
WMUPR (warm-up) 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.
CNTR (control rotation) 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).
PSTBY (print standby) The machine is in a state in which it is ready to accept a copy/print request signal.
Interval Description
PSTBY (standby) The machine is in a state in which it can accept a copy/print request signal.
PNTR (initial rotation) From when a print request signal is received until the image signal is generated.
PRINT (print) The machine is in a state in which a toner image is transferred to paper and the paper is discharged.
LSTR (last rotation) The machine is in a state in which paper has been discharged and all drive has ended.
