MFP M281cdw Error 79 crash when connected to network but not USB

HP Recommended
HP MFP M281cdw
Microsoft Windows 10 (64-bit)

My M281cdw gives me the 'Error 79 Service Error Turn Off then On' message and goes into an infinite reboot routine whenever connected to my home network. It will do this even when both PCs connected to the network are turned off. I have done the following:

Cleared all print jobs on both PCs

Unplugged the printer and left it unpowered for an hour

Reset the printer via setup menu on the LCD panel

Rebooted all devices on the network including the router

Turned off wifi on the printer so the only network connection is the ethernet cable

Tried connecting the printer to the network when no other devices except the router are on the network.

Did a firmware update

Tried the not-so-secret NVRAM reset

Switched Ethernet cables

 

The printer works fine when connected to a PC via USB cable, but will go into the Error 79 continuous reboot mode about 1 minute after having the ethernet cable reconnected *or* when the wifi gets turned back on, even when the only other device on the network is the router. I'd like to really get this back to working on a network, as I would prefer not to have to stop working and let my kid use my PC every time she needs to print something for school.

 

Anything I might be missing besides sending the printer back to the factory? Thanks in advance for any assistance you might be able to offer.

Hi,

Please unplug the Ethernet cable and then open the Setup menu.

Within the Network menu select Network Services and there select IPv6.

Disable IPv6 and press OK.

 

Now plug the Ethernet cable back and check for any difference.

Shlomi,

 

Thanks! That totally fixed the problem. I don't understand network protocols enough to know *why* that worked, but it did the job. Thanks so much for the quick help. Really appreciate it.
