Hello!
When your Canon MF267dw printer falls asleep and won't wake up for print jobs, the issue is often related to its power-saving or network settings. To fix this, first, check the Auto Sleep Time on the printer's menu and increase the duration to a longer period, or disable it entirely if that's an option. You should also look for and turn off any Power Save Mode settings. If the problem persists, try assigning a static IP address to the printer on your network to ensure a stable connection that won't be dropped when the printer goes to sleep.
