Traditional CIS sensor arrangement

Traditional CIS scanners use sensors designed for A4 scanners staggered across the scanner width.

These traditional CIS scanners scan different parts of the image at different times and use software to “stitch” the data back together.

What does this mean?

  • Not all the data is captured at the same time
  • Variations in document speed or feed inconsistencies can result in misaligned scan data.

SingleSensor is different

The patented Singlesensor technology uses up to 50,400 individual image sensors in a straight line across the width of the scanner.


What does this mean?

  • The entire document is scanned at the same time.
  • You produce a single image with no breaks.
  • The image is always properly aligned.
  • You get a better scan.




You need good light to produce crisp and clear scans.

Traditional CIS lighting

Traditional CIS scanners use a single LED light with a light guide to illuminate the entire scan surface.

What does this mean?

  • The sensor is illuminated from one side only.
  • As you move further from the single LED the light diminishes; different parts of the document are scanned with different light levels.

Clearview is different

ClearView uses up to 144 LED lights across the entire width of the scan surface.

What does this mean?

You always get bright and even light.

  • Each side of the sensor is lit up.
  • All sensors are lit equally, across the entire width of the surface.
  • You get a clearer, even scan.




Scanners work best when the document is held tightly against the scanner glass, directly opposite the sensor.

Traditional ‘hold up roller’ design

Traditional CIS scanners work with staggered sensors. With this configuration each CIS sensor has an individual roller to position the document next to the scan glass. As the document moves between the individual rollers it can sag.

What does this mean?

  • The rollers provide uneven pressure as they are not aligned across the full width of the document.
  • The pressure is reduced as lightweight documents free wheel through the scanner.
  • CIS has a short focal length, so with low and uneven pressure the resultant scan image will be out of focus.

SureDrive is different

SureDrive uses a single roller to provide even pressure across the full width of the document.

What does this mean?

You always have consistent high pressure directly opposite the scanning sensor.

  • A single full width roller provides even pressure across the full width of the document.
  • The roller has a motor drive to pull lightweight documents through the scanner. This allows the roller to use higher pressure than traditional rollers.
  • Your documents are always in focus and always produce a great scan.
