This too was a bite in my butt.
I have updated once remotely via WWRSPF and ... C-D706. In the morning the customer called us to find out why the printer went yesterday and not today. I later discovered that a firmware came out with the note "C-D706 could happen". I personally prefer to have regular maintenance. But sometimes, it's disheartening when these things happen.
