I am seeing an error message when trying to print from my HP Rocket Studio printer. It says there is a paper jam error. However, I have changed the paper, cartridges, and turned the printer off to solve but nothing has worked. It seems like a hardware issue so when I went to Support, it asked me for my printers serial number which when I typed in multiple times, was not “valid”. I can’t seem to get any help on this issue and I’m very frustrated. I would appreciate any help!
