I have received my second Dell B1165nfw Multifunction Mono Laser Printer, that will go into power save mode and never come back out. The only way to "wake it up is remove power and let it reinitialize.
I have changed the power save mode time and that will delay the problem.
I updated the firmware; http://www.dell.com/support/drivers/us/en/555/DriverDetails/Product/dell-b1165nfw?driverId=Y14X1&osCode=W732&fileId=3194317439&languageCode=en&categoryId=FW" with no change.
Any other suggestions, I really don't want to have to exchange another printer.
