6.6.2 DRIVE – TRAY 1, TRAY 2, AND BY-PASS TRAY
The paper feed motor [A] drives the pick-up and feed mechanisms in tray 1 [E], tray
2 [F], and the by-pass tray [G], using clutches and complex trains of gears (the
locations of the gear trains are indicated by dotted lines in the above diagram).
When tray 1 and tray 2 are inside the machine, their pick-up rollers [H][K] are
always in contact with each top sheet of the paper stack. On the other hand, the
pick-up roller [P] of the by-pass tray stays away until the by-pass pick-up solenoid
[Q] turns on. When the paper feed clutch [B][C][D] turns on, the pick-up, feed
[I][L][N], and separation [J][M][O] rollers start rotating to feed the paper. The paper
feed clutch stays on until shortly after the registration sensor activates.
