79 Error Turn Off then on and "Internal Processing Error

[X32543]

My HP Color LaserJet Pro MFP 281cdw is continuously restarting about every 1-2 minutes, and displays "79 Error Turn Off then on" before restarting. I have tried unplugging it from everything multiple times, and once for even a week. I have tried going to other settings, but receive "Internal Processing Error" every time. I cannot even attempt to update the firmware, as it does not stay online long enough. 

If anyone here could help me - please do.

Welcome to the HP support community.

Follow these steps to fix the issue:-

1. Turn the printer power off, wait at least 30 seconds, and then turn the power on and wait for it to initialize.

2. If you are using a surge protector, remove it and plug the printer directly into the wall socket. Turn the printer power on.

3. If the message persists, disconnect any network or USB cables and power cycle. If the printer returns to Ready, check the firmware version and update if a newer version is available.

   For instructions on updating the firmware, go to HP LaserJet Pro - Update the printer firmware.

4. If the error is intermittent, attempt to isolate the issue to something specific in your environment.

5. Delete all print jobs from all computers connected to the printer and send a simple test print job.

Unfortunately, I have done all of the above to no success.

However, I have determined that it only does this when connected to my wireless network. As soon as I disconnect the network - this problem stops. Firmware is up to date.
