Did the printer come with any utility programs?
Specifically, can the printer be reset (if not through software, is there a switch setting/sequence to do this)?
Can the jets be cleaned -- again, software or switch setting?
Have you tried removing and replacing the cartridge, in case it was bumped and unseated while you were unjamming the paper?
Sorry I can't be too much more help than this. My old HP 540 has been chugging along for ~10 years now. I've had problems like this (occasionally) and this is how I solved them. But "modern" printers are more complex than mine, and have even more intelligence in the cartridge than mine.
