If there is too much paper in the tray, unnecessa~
pressure may be placed on the Paper Pickup Roller
resulting in a paper jam. Remove the excess paper.
(Note: This condition may have permanently damaged
the Pickup Roller clutch.)
Push the paper tray fully into the printer. If the tray is
not square with the printer, remove the tray, lomte the
problem, and correct it.
Seat the paper tray lid.
With the tray removed from the printer, verify that
nothing is hindering the tray plate's movement. If the
plate does not move freely, replace the tray.
While instiling the tray in the printer, observe if the
plate moves up, positioning the paper against the Paper
Pickup Roller. If the lifi mechanism does not lift the
paper, correct or replace the mechanism.
Examine the tray for damage (refer to Figure 7-9). If any
protrusion is broken, replace the tray.
Examine the paper tray cavity in the printer for
microswitch lever damage (refer to Figure 7-9). If the
levers are damaged, replace them.
