Conclusion: The Xerox DocuMate 3125 is a reasonable choice for a desktop business scanner at its price, if you don't need to scan to searchable PDF format. It offers duplex scanning and a 50-sheet ADF. You can choose any of 9 programmable scan profiles using arrow buttons for one-touch scanning. Its OCR performance is reasonably good, particularly in greyscale mode.
Pros: Pretty compact, Has 9 programmable scan profiles, Good OCR performance in greyscale mode, Has a 50-sheet Automatic Document Feeder
Cons: Slightly sluggish scanning speed, Slower still scanning to searchable PDF
