Office Jet Pro 8730 Flashing Screen

[dracogiraffa2]

The screen, power button, and other LEDs on the printer flash repeatedly after a while in sleep mode.

• I have tried the HP Print and Scan Doctor software, it found nothing.
• I have tried the firmware update and it has the latest software.
• I have unplugged it for days and then plugged it back in and after it goes into sleep mode I return to catch it flashing again.

I can get my printer to work if I plug it back in to get something done, but if I leave it for a while it triggers this issue. I cannot push or hold the power button on it to get it to reset, only unplugging and replugging it back in will fix it temporarily.

I've had this printer for years and it works wonderfully for what I need occasionally to print 5 pages maybe once a month. If I cannot get this solved, it is unlikely I will purchase an HP printer again due to the maze of incompatible issues and questions for me to even get to this point to ask in the community forums.

I let the printer sit overnight again and finally it posted an error screen message. It was blue but still flashing on the other LEDs on the machine. The error is B83C0E74. Hopefully, that will help future people with this issue. I am going to start a search again on what this means.

I doubt I have any warranty to be covered. I've had the printer for years.
