The pick-up roller [A] and paper feed roller [B] are driven by the tray feed motor.
The pick-up roller picks up paper from the top of the stack. Friction between the
feed rollers and the friction pad [C] allows only the top sheet to pass towards the
tray exit rollers.
There is a one-way clutch in the paper feed roller. When the roller stops and paper
is fed by the tray exit rollers, the one-way clutch ensures that the paper feed roller
does not resist paper feed.

The friction pad [C] is pulled away from the feed roller by energizing the friction pad
solenoid [B] when a copy job finishes. It contacts the roller by energizing the
solenoid again when a copy job starts. This eases paper jam removal if paper is
caught between the roller and friction pad. Also, this mechanism helps to extend
the life of the roller and friction pad.
