imageCLASS MF751Cdw won't wake up from sleep mode unless we turn it off and on

Hello,

We have a Canon ImageClass MF751Cdw printer which prints fine, however, our HR department is having to turn the printer off in the evening then turn it back on in the mornings in order to print. If it's left on overnight or through the weekend it will not print until the printer is turned off then back on. It's a network printer. I have modified as much of the sleep settings as possible. Unfortunately I see no way to turn it off completely.

Has anyone had this problem and figured out a solution. Also, all firmware updates have been applied.

I am having the same issue with a new MF751CW. Got a decent deal on it for black friday... First printer that is not a Brother.... Starting to regret it already. Very annoying.

Thanks for the link, however, we are not using Air Print. The printer has a static IP. I've increased the sleep time as much as possible. It would be nice if it could be turned off. During the day it doesn't sleep because HR is printing to it most of the day. It's overnight that's the issue.
