Printer is HP C7280 all in one with pc using MS7. Keep getting new error codes everyytime I turn printer on. Tried holding # and 6 keys for 20 seconds with power off - then 20 secs with power on. Worked once. This started yesterday and I have no idea why. HP doesn't list error codes and their definitions

Try following this document. http://support.hp.com/us-en/document/c03081973
You can try running the Hardware Diagnostic Utility. Your printer may be too old for it to work, but it won't hurt to try it.

If the troubleshooting steps in this page do not resolve your issue likely the unit will require service.
