Excerpt: For those who prefer technical support via telephone as opposed to email, the Canon imageFORMULA DR-3010C includes a slightly better technical support policy than the Epson GT-20000 large format scanner . Canon and Epson provide free technical support during their one-year warranty periods. The Xerox DocuMate 515, however, includes a better technical support policy than either of them: telephone access for the life of the product.
Pros: The Canon imageFORMULA DR-3010C is ENERGY STAR compliant.
Cons: Although scan density is more than adequate, some competitors provide higher densities.
