I have two M425DN MFPs that won't completely 'wake up' when they are being brought out of sleep mode. When we tap the touchscreen, the backlight comes on, but the MFP does not respond otherwise. There is no 'beep', and the display doesn't change -- you can tap an icon and there is no response. I have updated the firmware to datecode 20131216 on both MFP's, but they both still exhibit this problem.
The only way to get the MFP to respond again is to power-cycle the MFP.
Both of the MFPs are not networked -- they are only used for faxing and copying.
We are concerned because we may not be receiving faxes overnight, and the staff are complaining about having to reboot the MFP's each morning and throughout the day as they 'go to sleep'.
Any ideas?
Thanks,
