Theory of Operation
2-19
Paper Pick for Trays 2 - 4
Note
Trays 3 and 4 are optional 525-Sheet Feeders.
To pick a sheet of paper, the media path drive starts the process. The pick clutch
engages to turn 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 first driven against non-rotating rollers. The rollers reverse during simplex, causing
a buckle in the paper. This ensures that the leading edge is straight to prevent skewing.
The deskew rollers will not reverse during duplex printing.
