I’ve got a MX-7040 with a FN19 finisher. I’ve been having this jamming issue that has been driving me nuts. Paper folds up in the beginning of the pass through unit around the first and second rollers on letter size only (right after leaving the fuser) resulting in PDPPD1_S and POD1_S jam codes. Happens after about 20 or so copies. Checked and cleaned all the rollers. Changed the paper type to 23-28# with no affect. Took the cover off the front of the drawer so I could see if the gate was closing or the tray rollers stopping and they all looked good. Set the paper type to pre-punched and it runs fine (just a lot slower). I’ve had to upgrade the firmware recently because of a SD card going bad as well. This is a usually reliable machine until recently with 150K BW and 240K color on it. Anything I’m missing?
