LCT tandem tray on MP4001

[Ltd]

If I have papers on right tray, left tray had no paper. the thing worked. But If I have papers on left tray , it detected papers and the heights but it did not move the stack to the right cause sc503 pop up. I replaced end fence sensor and gate sensor but no improved. This LCT had different main board than the one on Mpc.4500, I did not try new board yet.

It's either the drive/motor or the board. I'd check the motor first - dunno if that's a simple gearbox-motor or a stepper motor used for the paper stack movement.

There is a modification for this the drive gear slips, if you remove plate at bottom of left hand tray you will see it at end of drive shaft.

New gear= AB030831 Shaft = B8012733
