Unibody CIS Technology

Contex patented Unibody CIS technology, a unique image-capture design, based on a single aluminum extrusion and custom CIS modules ensuring market leading accuracy in every image.

Fast Data Transfer Rates with xDTR

Contex scanners with xDTR improve overall productivity by increasing the data transfer speed of the USB interface, so more image data can be sent to the PC, faster. This means larger documents (and more documents) can be scanned at higher resolutions without waiting for data transfer to complete. A scanner without xDTR may capture an A2 or C-size color document in eight seconds, while a scanner with xDTR can capture an A1 or D-size color document in the same time, or less. If scanning batches of documents or scanning at 400 dpi or more, the difference is even greater.
