DR- 7580 / DR- 9080C Product Features

Image Quality

At the heart of the DR-7580/9080C is Canon image sensor technology that features an optical

resolution of 600dpi and each sensor array has dual RGB LED light sources (to capture images

on the front and back side of documents) for the highest quality image capture. This arrangement

results in more even illumination even when scanning wrinkled or folded documents. They also

provide for full RGB color duplex dropout with the DR-7580 as well as the DR-9080C. Color

dropout is commonly used with forms to “drop-out” the form background for data processing. The

reverse, RGB enhance is also provided to facilitate enhancing certain colors contained in a stamp

or other critical color image data.

Built-in Shading Adjustment Boards automatically activates to calibrate the sensors between

every scanned batch, optimizing image output consistency. A “Smoothing” mode is available to

reduce moiré and improve overall image quality as illustrated below.
