On the list of supported SANE devices the scanner is listed as fully supported but it says:
resolution from 75 to 2400 dpi
Here is a link to Newegg's item listing, where it lists the optical resolution as:
2400 x 4800dpi
I'm a bit confused here - Is SANE's support not up to the full potential of the scanner? Am I reading this wrong or is the list just not specifying enough information to me?
