501	B	1st tray lift malfunction
The tray lift sensor is not activated after the tray lift motor has been on for 10 seconds. If the main 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 tray lift sensor should de-activate within 1.5 sec after the paper bottom plate starts to drop. If it does not deactivate within 1.5 sec., 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.
An obstruction (jammed paper, paper scraps, etc.) has blocked the motor drive and caused an overload. Tray lift sensor connection loose, disconnected, or damaged Tray lift sensor defective Tray lift motor connection loose, disconnected, or damaged Tray lift motor defective
