HP rolled out a firmware update that when using non-OEM toners the printer will show a 79 error and continuously reboot the printer. What needs to be done to resolve the error, is to downgrade the printer's firmware to the previous version.
To downgrade the printer’s firmware, you will need to connect the printer directly to a computer with a USB cable and disable the printer's WIFI.
Go to the printer menus and do the following

Download and extract the zip file from the link below.
Select your Printer to Update in the drop down
Click <Send Firmware> to begin the downgrade
The firmware downgrade can take up to 1 hour to complete. Please be patient, the printer should reboot itself when the firmware revision is complete.
After the printer completes its downgrade. You will need to disable the auto-update on the printer., so the firmware doesn't automatically update itself and break compatibility again
You can now enable the WIFI and hopefully, the 79 error is resolved.
If you have any questions or would like for us to send out a technician to perform the downgrade for you.
