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

the problem then this SC is displayed.
