Automatically Split Each Page In Seconds
Upgraded 40 MP CMOS Image Sensor




Patented Book Curve Flattening
The CZUR ET Ultra's patented book curve correction uses a smart page flattening algorithm along with three low power laser lines to analyze the contours of an open book. The smart algorithm, combined with accurate laser lines, analyze the scanned images and within 2 seconds, produce perfectly flat images. That means that your most valuable collections can be scanned perfectly without damaging them in the process.
OCR Technology Built In


Automatic Finger Removal
Scanning a bound book can be frustrating, but the CZUR ET Ultra overhead book scanner makes even the tightest bound books easy to scan. Simply lay the book down in the scan area, open the book and hold the pages down , and start scanning. The CZUR ET Ultra will not only flatten the page but will remove your fingers from the final image as well! Your images will be perfectly straight and finger-free every time.
