Epson Stylus Photo PX720WD
The PX72WD's scanner has a resolution of 2400 x 4800 dpi, which is far more than you will ever need for reflective scanning - most print scanning only needs to be performed at 300 or 600 dpi. The copy print scans of the Kodak reference prints produced clean colors - particularly impressive is the colors reproduction on the fruit and flowers. It is worth noting though that the scanner lid closes flush to the scan surface (platen) which limits the thickness of material that can be scanned. Scanning times are very fast, four seconds to scan in an A4 page and 2 minutes 28 seconds to scan and produce an A4 print.
HP Photosmart Premium X310
The HP Photosmart Premium C310 has the lowest resolution flatbed scanner of the three printers in this review, at only 1200 dpi. However, as previously stated, for the vast majority of purposes 300 to 600 dpi is perfectly adequate for reflective scanning (of printed materials). The low resolution isn't a problem, but scan quality, sadly, is. Our Kodak test scans and prints look dull and lifeless when compared to the other two printers and reference prints.
