Epson WorkForce DS-7500 Review
Basically a faster, more expensive version of the Epson WorkForce DS-6500($849.00 at Amazon), the Epson WorkForce DS-7500 delivers all the same strong points. In particular, it offers both a 100-sheet automatic document feeder (ADF) for heavy-duty scanning by small-office standards, plus a slightly larger than letter-size flatbed for originals, like bound pages, that won't go through the ADF. Unfortunately, although it's faster than the DS-6500, it's not enough faster to make a compelling case for the difference in price.
Epson rates the DS-7500 at 40 pages per minute (ppm) and 80 images per minute (ipm) for duplex (two-sided) scanning, with one image on each side of the page. Compared with the DS-6500's rating, that translates to being a full 15 ppm and 30 ipm faster. However, the real-world difference is a lot less.
