False paper jam error keeps popping up. I have cleaned the feed rollers and checked all possible areas for jammed paper and there is nothing. I have turned it off and on and disconnected the power cord to no avail. The firmware is updated to the current version. How do I perform a factory reset?
I'm having the same problem. The carriage is perfectly freely moving. There is absolutely no sign of a paper jam anywhere. It will print one page without issue, then a minute later give me the paper jam error when I try to print another page.
I have tried unplugging while the printer is on, waiting, plugging back in. I'm at my wits end.
Same issue with my OfficeJet Pro 6978. I think it's related to the defective 902 ink cartridges, and the printer detecting that I'm trying to use non-HP ink (only because the HP 902 cartridges have been out of stock for weeks). I've even taken it to a repair shop for a complete cleaning. It's infuriating that this otherwise perfectly fine printer won't print!
