Scan this, Nikon

The infamous Nikon scanner decided it didn’t want to scan any more. Or rather, it would scan, but the scan head wouldn’t move, resulting in some interesting modern art. I took the case off and looked for any obviously fixable mechanical problems, but couldn’t see any. It would probably be possible to get it working by disassembling the mechanism, but I’m not that mechanically oriented. It’s not like I’ve abused the scanner, and it has only had light residential use.
