Have you looked into using a camera to digitize books and manuals? As an example of the quality of the finished product, the Portable PLUS Service manual, was scanned with a smartphone and an app that corrects for trapezoidal effects, etc.

There are some fancy platforms/light tables available for the serious minded.
