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.
