Any help for a vintage Canon PC710 copier here?

[AABGM]

I know, it’s a printer forum... And I would not have thought to come here, but it was among the search results. I am looking for photos of the interior of a Canon PC710 copier. It crapped out with a small broken piece, and I was going to have a go at Krazy-gluing it before I have to junk it. But I can’t find where the piece goes. It holds the spring which pulls the gears shown, down to engage with some other gears. I think it’s ridiculous that one tiny plastic piece like this can destroy an entire big ‘tank’ of a copier. While I was sceptical that Krazy glue would hold under the tension anyway, it seemed worth a try if I could find where to stick the piece.
Can anyone help me find photos of the guts of this copier?
