Paper Feed
6.8.2 DRIVE – TRAY 1, TRAY 2, AND BY-PASS TRAY

Tray 1 and Tray 2

The paper feed motor [A] drives the pick-up and feed mechanisms in tray 1 [B], tray 2 [C]. It
uses clutches and complex trains of gears to do this.
When tray 1 and tray 2 are inside the machine, their pick-up rollers [D][E] are always in
contact with each top sheet of the paper stack ( "p.6-3 "Paper Lift – Trays 1 and 2"").
When the paper feed clutch [F] for tray 1 turns on, the pick-up, feed [J] and separation [K]
rollers start rotating to feed the paper. The paper from tray 2 is also fed in the same way.
The paper feed clutch stays on until shortly after the registration sensor activates.
By-pass Tray
The pick-up roller [A] of the by-pass tray stays away from the top of the stack of paper until
the by-pass pick-up solenoid turns on.
The duplex/by-pass motor [D] drives the pick-up, feed [B] and separation roller [C] through
the by-pass clutch [E] and gears.
