Several WC 5325s at my sites have the habit of entering sleep mode, then not waking up when I press any buttons or send print jobs. I have to shut off the machines, and reboot them.
I'm fully aware I can alter power saver/low energy timers online, but that does nothing since I have no idea how to solve my problem using those settings.
Is there some software issue causing this, or some other issue with settings that aren't obvious?
This is should have been fixed in Firmware a while ago, I believe everything after 53.20.41 has it fixed.
Latest firmware is 53.23.03 and is located here.
Give that a go and see if it resolves the matter.
