Paper Pick For Trays 2 - 4 - Xerox Phaser 8400 Service Manual

Paper Pick for Trays 2 - 4

Note
Trays 3 and 4 are 525-Sheet Feeders.
To pick a sheet of paper, the media path drive starts, and the pick clutch engages,
which turns the pick roller and the nudger roller. The nudge roller advances one sheet
of paper forward into the pick nip. The retard roller prevents two sheets from
advancing. The sheet of paper continues past the take-away rollers until the sheet
completes the deskew process. When using the optional 525-sheet feeder, paper is
pre-picked from the tray and staged in the paper path while the printer is printing
previous pages.
The deskew process uses a reverse/buckle deskew for all three paper paths. The paper
is driven against the non-rotating rollers, which are reversing during simplex, causing
a buckle in the paper ensuring the leading edge is straighten to prevent skewing. The
deskew rollers do not reverse during duplex printing.
