2nd 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.
