Duplex scanner scans 70 ppm.

Now, your workgroup can take advantage of ultra-fast two-sided scanning of critical business documents. The WorkForce DS-70000 delivers surprising speeds, racing through two-sided documents in just one pass, scanning everything from 2 7/10" x 4 7/10" to 11 7/10" x 100". Use the automatic document feeder to quickly scan stacks of one- or two-sided, large-size documents.

And, it consistently delivers vivid colors and crisp, sharp text thanks to its four-line CCD sensor. It even makes it easy to dropout selected colors or choose a color and convert it to black. With this versatile performer, you get high-volume, precision document imaging. Scan Size (W x H): 11 7/10" x 100"; Bit Depth of Color: 16 bit Internal; 8 bit External.
