I have an HP 451nw that came up with a tray 3 paper jam error. It started out as a fuser error so I replaced that and now it only has a "Tray 3 Paper Jam" error but I do not have a tray 3 installed. It will not print from any other tray, either.
I found and followed advice on other posts on this board but nothing has worked. I have replaced the DC Controller and the fuser, updated the firmware and drivers, and did a NVRAM reset. It has to be a software issue.
Anyone have any other solutions that have worked? I hate to trash it because it was a great printer and was used very little. I haven't even gotten through my first trays of toner. Ideas?
