Hp officejet pro 8600 power off and power on lights flashing

[Wayne1428]

My HP Officejet Pro 8600 -All-in-One Printer -
Printer Control Panel turns white flashing rapidly power off and power on message. The computer shows the printer as offline.  The only thing that works is power the printer off and on, or to physically unplug the printer and physically plug it back in and then the printer works as normal for about 15 minutes, then the control panel goes white and starts flashing again and the computer shows the printer offline again.  So it takes about 5-10 minutes every time I want to print a document, I have to go through all the steps each time.  Any ideas to correct this?

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

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.
