Hi - I have an HP OfficeJet 4630 which has been working fine for years until a couple days ago when we got a Carriage Jam message. The carriage does move and I've checked everywhere for jams and there aren't any. Following instructions on this forum, I updated my printer driver and then got an Error Code OX83C0000A NOS_LOADER_APP. After restarting the printer, I now have error code OXB8000448 and don't know what to do at this point. Can someone assist?
