Paper Tray
. The paper tray holds approximately 500 sheets and can accept the
following paper sizes: A4, A3, 11”x13” (Government Legal), LT, 8”x13”, LG, 11”x17
(Ledger).
Bottom Plate
. A coil spring below the bottom plate pushes the bottom plate and
paper stack up to maintain the correct paper height for feeding.
Paper end sensor
. A photosensor below the plate that detects when paper in the
paper tray has run out.
Paper size switches
. Four paper size switches (push switches) detect the size of
the paper loaded in the tray.
Paper near end sensor
. Actuates when about 50 sheets of paper remain in the
tray and lights the paper end LED green. After the last sheet feeds, the paper end
LED lights red to indicate paper out.
Paper feed
. The pick-up roller and feed roller feed the copy paper from the paper
tray, but only the bottom sheet is fed because the separation pawls prevent any
other sheets from feeding.
Skew correction
. The registration sensor detects the leading edge of the paper
and slows the feed motor (a stepper motor) long enough to buckle the edge of the
paper against the registration roller and correct skew.
