imageCLASS MF656Cdw How to disable sleep mode

[MaggieD]

Hello, we just purchased a MF656Cdw laser printer and it worked well printing from laptop and intermittently from mobile device. It was intermittent i believe due to the printer frequently going into sleep mode. Today, the printer does print from mobile or from laptop so i entered a timeframe to disable the sleep mode.  We looked at multiple troubleshooting ideas we found in this forum and the remote UI. We feel like there is something simple we are missing and are almost to the point of starting from scratch  with the initial setup. Any help would be appreciated. Today the printer does NOT print from mobile or laptop.

You do not say what operating system, computer, or type of network you are using, but before disabling sleep mode you may want to try reinstalling the printer, but this time do so using the printer's IP address, and then setting that IP address a static both on the printer and on your router.

MREG, this answer saved my printer woes today! My new MF656cdw was taking 12 minutes to print every single page, displaying a "waiting" message during that time. I reinstalled my printer using its IP address, and NOW IT'S WORKING! Thank you so very, very much for this suggestion!
