C308 "unable to enter sleep mode"

[nano2k]

I have a C308 that stays on all the time. It won't enter sleep or low power mode after the specified time, and even pressing the power key just gives the message "unable to enter sleep mode."

I've updated the firmware and function version, but it had no effect. All of the power save settings are set properly as far as I can see. Any ideas?

In my case, I was logged in as Administrator on my bizhub C3320i printer from a web page.
Once I logged out, I could send the printer in Sleep Mode.

Hi, thanks for your experience but your printer is completely different from the one in question. The series is also completely different. The thread is also old.
