Canon ImageCLASS MF644CDW Load Paper Issue

[EsteBeatDown]

Good evening everyone. I hope everyone's weekend started out well.

I am having an issue with the printer model listed in the subject. It's an issue with paper detection, I think. So recently, the printer stopped detecting when paper is in the tray. Namely, it will not detect a "fresh" load. For instance, if I undock Tray 1 and load paper into it, and then insert it back into the printer, the printer will not detect the paper in the tray (or it may not be detecting the tray itself, I'm unsure). It will constantly give me the "load paper" error.The only way to fix this issue is to power cycle the printer by directly unplugging it from the wall outlet for a minute or so and then plugging it back in (keep in mind, just powering it off with the power button will not work, it must be unplugged from the outlet while still on). I have tried everything else (all cleaning maintenance, paper settings, factory reset, windows updates and printer firmware updates, different types of paper, etc.) and nothing but power cycling will get the machine to detect the paper (or tray) again. It really is a pain and I am hoping I can get some help here. Thank you so much in advance.

Same here.  It works on mine with paper set to paper #2 (21lb)

Thanks for taking the time to post this simple fix to a painfully obscure issue.

I have a mf634cdw, after trying everything given above, I pulled out the multi-function tray on top of the draw, and discovered a small piece of paper was in there. When I removed that paper and pushed both trays back in the "load paper" error on the computer went away.  Also, on the UI the "tray empty" message also went away.
