I dissembled a printer/scanner for parts.

This is a belt and roller and I think it was used for the scanner.

I can not figure out how the belt fits on the roller?

The belt is a continuous piece and the pin for the roller will not come out unless it is forced out.

Can someone solved the mystery of how to mount the belt?

    The image of the roller is unclear. However, does the roller rest against the outside of the belt?? – DrMoishe Pippik Jun 16 '19 at 6:13
  • I agree with @DrMoishePippik -- could this roller just be used to push against the outside of the belt, to add tension? Here's an image. That would explain why you can't loop the belt through or around the roller. – BrettFromLA Jun 16 '19 at 14:05

The belt doesn’t feed around the roller. That roller is used as a tensioner, so the roller is entirely inside the belt with the roller pushing the belt outwards to keep it tight.
