Wrong media

1.
Ensure the correct media type and size is loaded in the correct tray. For the
multi-sheet bypass feeder, ensure the loaded media matches the control
panel settings.
2.
Inspect the paper tray for damage to the tray's paper size sensor actuators.
3. Test the printer's paper size sensors using the service test "Switch scan test"
on page 63. If the sensors test ok, then the engine controller board is
probably bad.
4. Replace the paper size sensor board's wiring harness.
