Trouble

within 5 seconds after the cooling fan
motor turned on.
1st tray lift malfunction
The paper height sensor did not activate after the tray lift motor was on for
10 sec.
Note: Normally, if the power switch is turned on when the paper is already at
the feed height, the paper height position is detected again. At this time, the
paper height sensor should de-activate within 5 sec. after the paper bottom
plate starts to drop. If it does not deactivate within 5 sec. after four attempts,
a message will prompt the user to reset Tray 1. After two attempts to release
the error by re-setting the paper tray, if this does not solve the problem then
this SC is displayed.
