After a page or two prints, the power, multiple lights flash. Each time I unplug this issue repeats

I did install new black and color ink cartridges, but this error happened before that.  I installed the ink cartridges hoping that was the issue.

Hi @LMSN 

Welcome to the HP Support Community! 

Thanks for posting your query! We're here to help you get back up and running.

We're thrilled to have the opportunity to assist you and provide a solution. We hope our assistance has been helpful! 

This could be due to several reasons for this error to occur, including hardware or software issues.

Let me share a few steps you can try to troubleshoot the issue.

1. Power/Hard Reset:

Let's do a power reset on your printer by following the steps below.

Press the Power button to turn on the printer.
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 15 seconds.
Plug the power cord back into the wall outlet.
Reconnect the power cord to the rear of the printer.
Note: Please connect the printer directly to a wall outlet.
If the printer does not turn on by itself, press the Power button to turn it on.

2. Restore the printer to the default network settings, and then use HP Smart App from your mobile device to connect the printer to your Wi-Fi network.

Step 1: 
Restore network default settings on the printer, to do that - Press and hold the Wireless  and Cancel  buttons until the Power button flashes, and then wait for the Wireless light to flash.

Step 2: 
Uninstall and re-install the HP Smart app on your mobile device.

Place the printer and the mobile device near the Wi-Fi router.

Turn on Wi-Fi on your mobile device and connect to your network. 
Enable Bluetooth on the mobile device so that HP Smart can detect the printer during the setup.

After installing HP Smart for iOS and Android, enable the mobile device location service and allow the app to use your location to detect the printer and offer solutions during setup.

In HP Smart, click Add Printer or the plus sign  to search for the printer, and then follow the instructions to complete the setup.

3. Update the firmware on an HP printer

HP regularly releases new firmware versions for printer enhancements, app updates, or issue fixes. Update the firmware regularly to get the most out of your printer.
