My M725z printer won't wake up after a long sleep, I can not ping the printer and the touch screen will not turn on. Only way is to power cycle it.
I have a 5min timer for it to go sleep and when I print say 30min later, it works fine. Wakes up and prints. But say if no one prints over the weekend, the printer is unresponsive. I don't know how long it takes before it won't wake up anymore. I have to power cycle it each time.
I have updated the firmware to the latest available.
