I got to work on an interesting printer today, a dual tray P4515 printer with a very specific and very odd jam.
When tray 1 or tray 3 is used no jams, runs just fine.
When tray 2 is used it will either pull one piece of paper, which will come out blank and clears the fuser, sits halfway out of the exit. This doesn't always happen. But what will always happen is there will be one sheet that will go up, and just as it hits the transfer roller, there is a grinding noise (it sounds like gears clicking) and it stops dead. The piece of paper is about an inch and a half past the transfer roller with nothing but a dirtyish black line across the page.
It sounds like the grinding noise is coming more from the front of the printer.
As I said, the manual feed tray and tray 3 which has to feed past tray 2, does not jam at all.
I tried swapping cassettes, changed the rollers, tried another toner cartridge, checked the tray 2 feed solenoid, checked the action of the rollers, and tried to at least manually move the tray 2 paper pickup drive assembly.
Any ideas or suggestions?
Thanks.
