1,500-sheet feeder pickup and feeding
Three switches on the paper-feeder driver detect the media size and the presence of the 1,500-sheet
tray. The relationship between the switch combinations and the paper sizes is the same as for the
printer.
The main motor (M101) drives the paper feeder. When the dc controller PCA sends a print
command, the main motor begins to rotate. When the scanner motor reaches its prescribed speed,
the paper-feeder driver receives the pickup command from the dc controller PCA and activates the
paper pick-up solenoid. (The main motor drives the pick-up roller, feed roller, and separation roller.)
The pick-up roller, when the solenoid activates it, rotates once and picks up the media in the tray.
The separation roller removes any additional sheets and the media travels to the pre-feed sensor
(PS102).
The sheet then reaches the registration assembly, where its skew is corrected. The sheet advances
through transfer, separation, and fusing stages; passes through the delivery unit; and is delivered to
the output bin.
NOTE The 1,500-sheet feeder detects pickup-and-feed jams the same way the printer does.
