Continous Blank Screen

[ALhesse]

My officejey 8720 screen keeps going blank. I will press the power button and it will reboot and be functional again. After a few hours the screen will go blank again.

While it is blank it will not print and cannot be seen by any device. 

I have the printer connected through a hard line connection.

Hi @ALhesse,

I'd like to help!

I understand the printer goes black intermittently.

Try the below suggestions-

Let's try a power reset on the printer

Reset the product

• 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 printer.
• Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

 Also, try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware

Hope this helps! Keep me posted.

I did try this,  but it didn't work.  I've also check with updates. Held the power button when off to get rid of any residual power.  Everyone the screen goes back to white.

We can perform a factory defaults on the printer to resolve the issue

• The reset instructions are specific for your printer and performing those steps on a different printer may corrupt the device.
• I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer.
