I got new cartridges and after the head and nozzle cleaning I was going through the alignment process. It did no go through and started giving me a paper jam issue, I removed the tray and the back tray but there was no paper stuck anywhere. Now I have checked all of my printer and there is not even a sign of a tiny piece of paper anywhere. It still however gives me the Paper Jam error. Can someone help me fix this?

@diabolicboy take out all of the ink cartridges and power off. After a short while turn the printer on and see if it tells you to repalce the cartridges. Then reinstall those and let us know what you get.

Great ! Work for me on epson WF-3620 as crazy it could be. I spent hours before to check all sensors in the paper way, and this cartridges trick allow the system to be back on track. This paper jam error message is not describing a real issue. just life !#^& off… thanks to Murphy law. Thanks again oldturkey03
