Ensure that the clamp holds media firmly; clean it.
Ensure that no foreign matter interrupts the paper clamp
sensor.
Ensure that the bail rollers operate smoothly and correctly.

loaded in the tray. The actual paper size is not sensed by the
print engine.
Ensure that paper-pass sensor 1 and 2 are operational and
properly adjusted. Refer to the topic “Switch and interrupt
sensor checks” on page 9-8.
