We have an HP LaserJet 4050TN printer that continuously jams (13.1 & 13.6 errors).
It grabs the paper and starts to guide it through. . . then it jams as soon as the page reaches the NEW transfer roller.
A maintenance kit and new toner cartridge were installed, but it still keeps jamming.
If we put a piece of paper through the manual feeder, it will allow the 1st page to feed all the way through. But the second page jams.
We've taken it apart as much as we know to.
Any suggestion or idea what to ckeck why it keeps jamming?
