7/13/2000
Time interval from the resist roller clutch (RRC) ON timing to the OPC
drum separation pawl drive solenoid (PSPS) ON.
When the set value is increased, the timing is delayed. When the set
value is changed by 1, the timing is changed by about 1.0msec.

Adjustment
Used to adjust the contact pressure of paper onto the
resist roller in each section (copier paper feed section,
duplex paper feed section, SPF paper feed section).
(When the print image position varies greatly for the pa-
per or when a lot of paper jam troubles occur, the ad-
justment is required.)
