Error
Solution
Media tray indicates
empty when it is not.
If there is media in the tray, then check the media tray
microswitches (on the right side of the tray slot).
Check to see if the paper empty flag is broken.
Check the switch-tripping projections on the rear of the tray.
Transfer roll out indicated
when it is not.
A transfer roll out condition occurs when the mark sensors no
longer detect the marks on the leading edge of the yellow
panels of the transfer roll. If the transfer roll has not run out,
check to see that the transfer roll is properly passing the
transfer roll sensors. Ensure that the transfer roll is not slack
or skewed and aligns properly with the sensors.
