<!-- from fixya rte -->Output bin jam but no paper - HP LaserJet 3050 All-In-One Printer

SOURCE: how to clear paper jam in output bin

The printed page comes through the hot fuser at the top of the printer, through the exit rollers an end up in the exit bin.
We cleared a massive paper jam out of the fuser, by removing the grey surround on top of the printer. The plastic hooks that hold it in place get broken in the process, then you will the jammed paper between the fuser rollers, and the exit rollers. A technician can do it for you, but is unessersarly costly.

Try taking all of the paper out of the paper tray and try to pull it from the front of the printer.

this is a common fault. look where the paper was jammed, you may need a torch. There is a black or white sensor there that has been dislodged. Once clipped back into place it will then report to the printer that the paper path is clear and no longer a jam.

my experience says jamming in duplex area using card stock. this may occur if default is duplexing. set default to single side and / or try same job using plain a4 80gm2
