Paper jam error yet there is no paper: HP 9250C

The official HP website page for trouble shooting the printers HP OfficeJet Pro X series - Resolve paper jams including "Print Zone" jams ' HP® Customer Support

Try using compressed air to blow it out.. or use a compressor that can do 150 psi.. you might have dust in the sensor..

Try loading 1 paper only, keep an eye to see where it jams. It might be the roller or the pad. You also might have a a paper clip or some object in the paper path.

An error code showing that there is paper jam alert, but no paper is in anywhere in the machine except in the tray.....I have checked all areas, taken the back carriage of the unit, opened the top and opened the machine. removed the paper tray, everything, but there is no paper stuck in the unit

there are a lot of paper sensor in it. i dont say buy new one , check sensors where they are and try to clean

hi...open the printer then clean..i think theirs a lot of DUST that's why printer said paper jam

This video won't help if it's really broken, but shows you what to do for a recurring jam on the 6310.

Clean the contacts on the HP Cartridge. I've had the same error before and i switched it to a fresh new cartridge.. works fine ever since. THen i decided to switch back to the old cartridge, same error as you but i cleaned the contacts on the cartridge, works for a while but done after a week. Problem is that the ribbon circuit is rusted and the printer doesnt recognize the ink anymore.

Also make sure you both have the ink cartridges in place. Make sure it is seated properly inside.

hope this helps!

if u have had a paper jam previously u may have damaged the paper sensor when u removed the paper

check for a small piece logged inside, remove the toner cart and check that, take paper out and check under that
