imageCLASS MF656Cdw - Broken piece (roller)

[ltate]

Good Evening, All!

I have a Canon MF656Cdw printer which had a printer jam with laser business cards.  I got most of the pieces out and when I removed the paper tray and turned it on its side, I found a loose roller sitting there and I cannot figure out where it belongs.  Please help.  I searched it and it came up "frame retard roller with and spring". How do I put this thing back on?

Thanks so much, Leatrice
