Hello Lelze_Bill,
I searched the Support Page and found this article that has a few things you can try to resolve the issue.
My printer initially worked perfectly but lately it hangs up, unresponsive to any control panel buttons and can only be reset by cycling the power. I have tried with it connected by both cable and wireless. It seems to happen every 2-3 days. Would a power filter possibly help? It has the latest firmware installed. Thanks,
