Superior Image Quality

In addition to compact design, the advanced sensor technology of the DR-2050C and DR-

2050SP offers other advantages over conventional Charge Coupled Device (CCD) and Optical

Reduction technologies. Multiple lenses mounted along the width the DR-2050C’s sensor helps

minimize potential image distortion. Whereas a sensor unit with reduction optics has only one

lens; if a document is not completely flat on the guide glass, some points of the page will be

further from the lens than others, resulting in image distortion.

Image Distortion: Lens Array vs. Reduction Optics

Furthermore, a short light path does not require a strong light source. So instead of using

fluorescent lights, the DR-2050C uses LEDs, a light source that consumes less electricity.

Additionally, fluorescent lights require time to warm up, but LEDs do not. As a result, the DR-

2050C and DR-2050SP are ready to start scanning from the moment the power switch is turned

on.

Fast Throughput

The DR-2050C and DR-2050SP offer competitive scanning speeds compared to other models in

its category with a rated speed of up to 20 ppm or 40 ipm (LTR/200 dpi/portrait) in B/W and

Grayscale modes.
