6500i J0518

[D_L_P]

Since I asked about the J6210, I thought of another question. I have five 6500i's, all have above 1 million on the counter, that have been giving J0518 jams only when duplexing. I've done everything in the troubleshooting guide except replace the $600 conveying unit. The odd thing is all but one will duplex fine from tray 1 or 2. Can't even get 30 pages before it jams from tray 3 or 4. I replaced all the drive clutches in tray 3/4 and the vertical feed ones as well (which was no small task to do in 5 6500i's). That fix'd three of them. I completely disassembled the conveyance unit and scrubbed all the rollers, which helped in the other two, but I still see some j0518 code in their history. Anyone here fought with this jam code as well?

Sounds like maybe the vert path roller or the transport rollers for tray 4 could be causing your timing issue.
I have also noticed 0500 series jams when the paper is just thrown into the decks, and if you look you will notice, that a few pieces have the lead or trail edge buckled.
