SYNCHRONIZING ROLLERS19
The Synchronizing Rollers, operating in phase with the Scanners’ scan motion and
paper feeding, synchronize the leading edge of the copy paper accurately with the
leading edge of the toner image on the PC Drum.
The Upper Synchronizing Roller is a metal roller covered with a polyvinyl chloride
tubing, while the Lower one is a rubber roller.

To facilitate clearing of misfeeds, the Upper Synchronizing Roller is installed in the
Imaging Unit. It is fitted to the Guide Frame of the Imaging Unit and the
Compression Springs at the front and rear ends press the Roller downward so that
it makes contact with the Lower Synchronizing Roller. The Lower Roller is driven
by the drive source, while there is a gear train that transmits the rotation of the Lower
Roller to the Upper Roller, thus ensuring good paper transport performance.
To ensure good image transfer during conditions of high humidity, the Pre-Synch
Guide Plate is electrically floated by a plastic spacer, grounded through an 82MΩ
resistor and 1kV varistor.
