DR-2050C / DR-2050SP Core Scanning Technologies

(Connected to a PC)

When it comes to cost-effective, reliable document scanning, look no further than the DR-2050C

and DR-2050SP. An ideal choice for low-volume image capture or distributed scanning

environments, it achieves fast scanning at speeds up to 20 pages per minute (Letter/200

dpi/portrait) in Black and White or Grayscale and easily handles double sided documents up to

40 images per minute. With an output resolution up to 600dpi, the DR-2050C offers superior,

high-quality scanning in black-and-white (binary), 256-level grayscale, or 24-bit color.

Sleek, Space Saving Design

Measuring just 7.7” (H) x 11.7” (W) x 3.9” (D) and weighing in at 5 lb., the DR-2050C can easily

be moved around and set up quickly, even in the busiest desktop or countertop spaces.

The key to the DR-2050C and DR-2050SP’s compact size is its CMOS Contact Image Sensor

(CIS). This is a self-contained sensor unit with 3 major components: a row of sensor elements,

thin optics, and a light source (LEDs). The CIS unit is far smaller than conventional CCD-based

sensor units, which use a bulky mirror-and-lens system known as “reduction optics.”

Unlike reduction optics, which have only one lens, the DR-2050C and DR-2050SP’s optics are

made up of a row of numerous small lenses. This design significantly shortens the light path

required to illuminate the document. As a result, these scanner have a very small footprint.
