HP Officejet Pro 8500 printer message "Paper jam"

There still might be a small piece of paper blocking the sensor so check very carefully.

If you have cleared off the paper jammed within then it is possible that errors have crept into the drivers. sometimes the printer driver software can have errors while being in use or is shut down. So to reset remove your printer from the PC and uninstall the printer software. Now reinstall the printer software and then connect the Printer to be detected as a new hardware as it will be installed. Now check the printer properties to see the ink levels.
Activate head cleaning before a test is taken . Also check the mechanical settings of the ink cartridge , if jammed or tight remove motor and manually free the drive before it is set back.

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.

you need to open the printer and then fix it

Hi
This is a coomon problem with the printer the best thing to do is call HP and advise them of the issue. I recently had a customer who did this and even know it was out of warranty they replaced the printer.

Thanks

Constant jam indication. This gear is more than likely the cause after exhausting all other avenues. Also nearly impossible to get to let alone replace even if HP offered the part. There is a black cover over the clutch assy that can be removed to reveal the gear. In most cases the gear is either sitting in the bottom of the machine or split down one side. This is the second machine that I have diagnosed with this problem in a very short time. If you have this broken gear, consider it toast. Matt / E-tech Copier and printer repair.
