My HP OfficeJet Pro 8720 has blinking lights and a solid white display

HP Recommended
HP OfficeJet Pro 8720
Microsoft Windows 10 (64-bit)

Hello!

My 8720 goes into an error state where all the lights are blinking (e.g. power button, status lights) and the display is all white.

  • I have unplugged the power, waited 60 seconds
  • I have pressed the power on button multiple times during the past two weeks to reset the printer
  • the printer will print and appear to act normally after I reset the printer
  • the printer goes back into the blinking state either within minutes or hours.  It has happened multiple times and I expect it to happen again
  • I have an Instant Ink account, and I understand firmware updates are handled automatically
  • I printed an Event Log Report and have repeated HW events B8A1A8F0
  • The System events include:
    • 1390 74899 1 RepNo=975;Desc=Event Log
    • 1389 69666 1 3097602288
    • 1388 69442 1 FROM_NVM
    • ...there are more

Could use some help in identifying the specific problem and what I should be doing next.  I also have a MacBook Pro running Catalina that prints to it.   Thanks for your help.

 

regards, Bill

I am having the same issue.  This would very rarely occur on the printer but more recently as of the past few weeks it happens once or twice daily.  I have done some rudimentary troubleshooting but have not been able to correlate it with anything thus far.

I just saw your reply.  I have been having the same issue since my original post.  I would reset the printer, blinking goes away, I can print just fine.  Copy function works fine.

I reset the printer so it could be communicated to.  Otherwise nothing saw it.  I download the Print and Scan Doctor app version 5.5.2,  and ran that. I got this screen:

 I did a Test Print, got a solid black printout - great....  I did the Recommended Updates, don't know what was installed.  Same green status and Test Page solid black.  I did a clean print heads function - same result.  I printed a regular document - printed fine.  I copied a multi-colored advertisement - looked fine.  I went into the menu function of the printer Setup > Reports > Print Quality Report.  Perfect. 

Will the printer go back to blinking lights and white screen?  Don't know but stay tuned.  I will wait a couple of days to see if it happens.  Can I account for the solid black Test Page of the Scan and Print Doctor? No.  So much for the confidence in that program.

Welcome to the HP support community.

 

Follow the below steps to fix the issue:-

Use HP Print and Scan Doctor to fix connectivity and printing issues.

Download HP Print and Scan Doctor.

  1. Run HPPSdr.exe from the download location on your computer.

  2. Once HP Print and Scan Doctor opens, click Start, and then select your printer.

    • If your printer is not in the list, turn it off and on, and then click Retry.

    • If there is a connection problem, follow the instructions in HP Print and Scan Doctor.

  3. If a screen prompts you to turn on printer updates, click Yes.

  4. If a screen prompts you to make your printer the default printer, click Yes.

  5. Try to print.

Assign a manual IP address and that should fix the issue.

Find the printer IP address to assign it manually.

  1. Load plain white paper in the input tray.

  2. From the home screen on the printer control panel, swipe down to open the Dashboard, and then touch the Setup icon .

  3. Swipe up on the display, and then touch Reports.

  4. Touch Network Configuration Report.

Setting a Static IP Address

Once you know your printer’s IP address from the page you printed, entering it is pretty easy. Here’s what you do:

HP Printer Static IP Address

  1. Run your Web browser.
  2. In the Web browser’s address bar, type the IP address of your printer and press Enter. Assuming you entered the right address, the HP printer control panel should appear.
  3. Click the Networking tab.
  4. Under Connections, click Wireless.
  5. Under IP Address Configuration, click Manual IP.
  6. Enter the IP address, subnet mask, and default gateway in the appropriate boxes.
  7. Click Apply.

Let me know how it goes.

To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.

Cheers.
