Printer unresponsive unless restarted

HP Recommended
8500 910a

Since installation of new modem, printer remains connected to wifi but not to or recognized by devices. Also touch screen and on/off button of printer are unresponsive. I must unplug from power source and reconnect, then printer functions and is recognized by computer and android phone...for a short time only.

Occasionally, for some unknown reason or event, all the lights on the printer are flashing frantically saying to turn off. At this time, the on/off button does work and so does printer..again for a short time.

Printer is Officejet Pro 8500 A910

Devices Samsung Galaxy s8 using 9

Lenova computer 10

HP Pavillion Windows 10

@vrcsmith42Eeer Welcome to HP Community!


I understand that printer unresponsive unless restarted.


Please perform the hard reset and check.


Turn the printer on, if it is not already on. 


Wait until the printer is idle and silent before you continue. 


With the printer turned on, disconnect the power cord from the rear of the printer. 


Unplug the power cord from the wall outlet. 


Wait at least 60 seconds. 


Plug the power cord back into the wall outlet. 


Reconnect the power cord to the rear of the printer. 


Turn on the printer, if it does not automatically turn on. 


Wait until the printer is idle and silent before you proceed 


Use HP Print and Scan Doctor 

Download HP Print and Scan Doctor and run the program. It will automatically diagnose and fix any printer connectivity issues.
