MF632C/634C Duplex Keeps Defaulting to "Off"

[fluvius]

I think this started with Windows 11 but my Duplex setting defaults to "Off". I then do not get the option to print double-sided. I fixed it the other day but it is back to "Off" again. I just did a reset of the settings on the printer and it started as "Off", this did not happen before. I just removed the printer and added it again and I can set it through Windows but it thinks I need to do it manually now.

Please help, this was working perfectly before.

Now, I think I have fixed the Duplex issue but my print jobs just sit there. I was able to add the printer after removing it but it won't print the jobs. I tried using my phone and it worked but not on my Windows 11 PC.

It's official that it resets itself after a restart. the only solution I have is to remove the printer and add it again every time I need to print. It looks like the printer kept the setting "On" this time.

Canon, please help!!
