Canon MF9220cdn Reporting there's a jam when there is none

[katflp]

It says there is a paper jam in Drawer 1.  But there isn't, and I have gone through every other possible part and there is no paper jammed anywhere.  After I follow the steps, I can hit OK says something "printing suspended" while I hear things moving like it's going to print, but then it makes that error beep and says there's a paper jam.

Figured it out. I took out the Drawer 1 paper tray, removed all paper and noticed the tab (the part that goes into the printer 1st) that you slide to adjust to different paper sizes was stuck (not moving normally at least). I pressed hard on the light blue tab  and forced that piece to move back and forth a few times, I also removed any white paper that looks like it was folded or dinged up on the edges and put Drawer 1 back in. Then it started to print normally.
