My Deskjet 3050A is displaying error code OXB04020A7 and will not print. I've followed online troubleshooting guidance and have turned the printer on/ff a few times; each time I get a different error code. I've had (amongst others) OXB04020A7 and OXB013372E. The printer's been working fine but has just suddenly developed this problem.
