HP 4000 N (13.20 Paper Jam - Check Rear Door) Nightmare

ok, heres the situation.

I purchased a second hand duplexer unit off eBay and installed on Friday, however, the power cable didn't have an angled head so I removed the Duplexer until I can get a better power cable.

Since removing the duplexer I keep getting the error

13.20 Paper Jam
Check Rear Door

I have been through the printer from top to bottom, I did find a tiny piece of paper near tray 1 which I removed, and I have also sprayed all the dust out using a sprayduster can.

Ive got the following from the event log ...

30  13.32.48

29  13.16.24

28  13.16.24

27  13.01.80

I have searched the web and find a lot of talk about checking sensors, however im uncertain what sensors I need to check and what they even look like.

Any one who can help me clear this error would be greatly appreciated!

    Accepted Solution

    i would re-install the duplexer and see of the errors go away.

    Probably is an internal setting that can be set on the control panel of the printer, tedious, or through the HP Jet Admin software.

    Good Luck,

    It resolved now. I tried re-installing the duplexer and the error indeed did go away, however, when I removed it again it returned. It turned out to be a lever on the top back right hand side that was in the wrong position.

    I also had the same problem with my HP 4000 TN.

    Same 13.20 Error. The lever mentioned (in the back upper right, that is attached to the [duplexer or fuser?]) was not in the right place. The sensor for the lever had a broken tab and was not allowing the lever to return to the correct position. re-seating the sensor solved the problem.

    Thanks for the help... guided me to the right place.
