I experience the following issues. I think it may have been after an automatic firmware update:
* Sometimes it will not even power on when I press the power button.
* If it does power on, it usually gets stuck on the HP screen or shows a blue screen with one of several error codes, like: B84507AE, B80A0AEC, 00541654, B3A7AAFC, B8A7451E, and others. It seems like the system cycles through a dozen different failure modes and error codes and is not consistently the same each time.
* If it does make it to the home menu screen, it faults out there after a few seconds or the screen changes to black and white stripes or some kind of distortion.
There is no way to do a factory reset, as I cannot even get the printer to turn on and let me use the menu screen or connect via wifi. Basically the printer seems like it is "bricked."
Yes, I have tried dozens of time to use a different cord or outlet, powering off and on. I have even noticed that a desk lamp in the same room flickers briefly as I plug the printer cord in. I even changed the power supply to no avail.
