I have a Laserjet 4000 with 2-500 page trays installed and when I send a job to it, let's say to tray 3, both trays will pull paper simultaneously which will result in a paperjam...I have tried a cold reset but that's about it...Removed the duplexer and the fuser...Any thought? Thanks!

This HP printer has a small relay that transfers motor rotation from one part of the linkage to the next for tray selection. It is a relay that operates a clutch to send rotation from one tray to the next and allowing the first tray to become inactive and the second to work. Either the driver on the board has failed and is stuck on or the relay is jammed and is turning both pickup shafts.
