9.7 PAPER FEED DRIVE MECHANISM (FRR)
The feed roller is driven by the main chain [A] through the drive gear. The
feed timing is controlled by the paper feed clutch [B]. The drive gear turns the
pick-up roller [C] through an idle gear. The separation roller [G] and the grip
roller [D] are driven by the main chain through the drive gear. These rollers
are always rotating when the main motor is rotating.
The pick up roller is normally in contact with the paper stack. The pick-up
solenoid [E] raises the pick-up roller. When the leading edge of the paper
passes between the feed roller [F] and separation roller [G], the pick-up roller
is then lifted to its upper position out of the paper path.
After the trailing edge of the paper passes under the pick-up roller, the pick-
up roller drops back onto the paper stack in preparation for the next copy
cycle.
