1. You really need to provide more information in your posts. I hate having to do basic-level research on questions like this, such as "what the heck is a Summit photofix copier?", before I can get to the meat of the problem.
2. Did you try using google and the lq search function? Your question may have been answered already.
3. Looking at the sane and vuescan supported scanners page (links in my sig), I don't see it listed, which is not uncommon for a niche peripheral like this. Unless the manufacturer supplies a driver for it, I don't think there's any support for it.
