MX-FN11 on MX-M503N F1-15 code

[Dustin(WOP)]

Hello all
Just wondering if anyone else has experienced an F1-15 error code on this copier. I know that it is tray lift motor operation trouble on the finisher. We have tested the motors within sims and replaced the finisher control PWB, but nothing has corrected the problem yet. Just wondering if anyone has any brain storms for me.
Thanks for any advice on this issue. Have a great day!!

(also updated firmware)

I had one of these where the front cover was not installed properly on the finisher. As the tray lifts, there is the guide in the middle that is forced up by a small plastic tab. Because of the front cover, the tab would skip over the push point and give an F1-15 error. Hope it helps.

Another tech found and fixed the problem. The flag on the paper detect up unit was broken off. Replaced with a new one and all problems went away. Thanks for the help!!
