HP Laserjet 4345 mfp paper jam.

Here are some steps you can try to resolve the issue:

Clear the jammed paper: Open tray 2 and remove any jammed paper. Open the rear door and look for and clear any paper present or obstructions in the paper path. Open rear cover. Clear Jam. Close the rear door to allow the printer to attempt to clear the jam message.

Check the fuser unit: If clearing the jammed paper doesn't resolve the issue, it's possible that the paper is stuck in the fuser unit or that the fuser exit sensor is broken. In this case, you will need to remove covers, flat bed scanner, and fuser to check for any obstructions .https://www.youtube.com/watch?v=Lz9cTnbuDbw

Bad problem , check if there is some piece of paper ... otherwise yuo need a thecnic , may be is a paper sensor damaged .

First step is to unplug your printer, leave it unplugged for 30 seconds and then plug it back in.

Check inside the MFP (manual feed tray) for a scrap or a whole sheet of paper.
There is one of three sensors that is sending a paper jam notice to the printer.

Hi!

According to HP service manuals, the error you described is in the category:

JAM INSIDE TOP COVER AREA

and more specific:

The pre-feed sensor, the top-of-page sensor, or the fuser-delivery

Those are the points where some paper pieces or even dust can be stuck.


Hope it helped,

Bogdan

This error message is displayed by the printer when paper is jammed in one or more locations. In such a case, users are recommended to remove the jammed paper from the specified location. The entire paper path must be checked for any pieces of paper. To stop the message, open and close the top most cover of the printer. Lastly, verify the flags and the sensors. If the problem persists, the cause of the error message could be a broken sensor or sensor lever.

if you are getting a paper jam message but you can not find paper any where in the printer the first thing that you want to do is clean the pickup roller in the paper tray. the roller is located on the top of the cavity that the paper tray is installed in.

13.20.00 can be also caused be a jam near the fuser (the part of the printer that gets hot to make the toner stick to the paper). Remove the toner cartridge and take a look for small scraps of paper along the whole path. Also open the door on the back of the printer and look for paper scraps from there. If you see paper stuck in the fuser, do not use anything sharp to remove it, be careful not to scratch the surfaces.
