I have a HP F370, which shows paper jam error, even if it is all fine inside the printer, with the cartridges at their original positions. Because of this it doesn’t print any document or pictures. Please help.
did you look into cleaning the detectors or did you find out what caused the issue? Please let us know how you were able to fix it or whether you need more help. Thank you!
You can try out these steps mentioned on HP's Support Site.
Here's the complete Support Guide. It could be a software or driver issue too. So, as a last resort you can try reinstalling the printer driver.
The jam detectors I assume are light sensitive. They might be dusty. Try blowing out your printer with computer compressed air. Also look carefully in all the pathways of the paper for little bits of it.
