18-1. Upper Synchronizing Roller Positioning

Since the Upper Synchronizing Roller is fitted to the Imaging Unit, it must be correctly posi-
tioned with reference to the Lower Synchronizing Roller when the Upper Half of the copier
is swung down into the locked position. For this purpose, slots are cut in the lower copier
frame and the Bushings of the Upper Synchronizing Roller fit into these slots.
The Upper Synchronizing Roller is grounded through the Bushings which are in contact
with the frame. To positively ground the Roller, the Ground Plate fitted to the lower frame
makes contact with the Shaft of the Upper Synchronizing Roller.

18-2. Paper Dust Remover

The Paper Dust Remover is installed so that it makes contact with the Upper Synchronizing
Roller. Since the Upper Synchronizing Roller is covered with a vinyl tubing, triboelectric
charging occurs as the Roller turns in contact with the Paper Dust Remover. As paper is
then fed between the Synchronizing Rollers, the charges on the tubing attract paper dust
from the paper. The dust is then transferred onto the Paper Dust Remover.
