We are seeing the device "locking up" after "sleeping" - how to resolve this?
First time lockup was found in the morning of day 1. Machine is black screen after overnight idle. Power Saver button background light is ON which means machine is on power save mode or sleeping mode. But no response when press buttons.
Second time was found at mid day of day 2. Machine went black screen 20 min after used for a scan. All button background lights are OFF. No response when press buttons.
Third time in the afternoon of day 2. Power Saver button background light is ON but no response when press buttons.
While it's locked up, MFD web page is not reachable.
