Advanced Features Make It Easier
Paper handling can be a headache with some scanners, but not with the fi-4640S. In fact, its automatic document feeder will handle up to 100 sheets at a time, freeing you to do other things. The hopper can accept both square edge and fanned paper stacks helping to eliminate paper jams and increase overall scanner productivity.

What's more, the scanner features an intelligent control panel that communicates in plain English, making it easier to use and you more productive.

To maximise throughput the fi-4640S incorporates double feed detection by both paper length and thickness.

Enhancement Technology Makes It Better
Fuijtsu's revolutionary IPC4D Image Enhancement Technology (IPC)TM delivers unparalleled image quality while maintaining its high throughput to provide the following features:

• automatic seperation -- accurately scans your black and white text, and greyscale or halftone photos in a single pass, saving you valuable time;
• dynamic thresholding -- by automatically adjusting contrast levels, dynamic thresholding increases the accuracy of low-contrast documents that contain handwritten or typed characters with varying line thickness;
• noise removal -- removes particles on copied or faxed documents for better optical character recognition (OCR) read rates;
• subwindows -- allows you to zero in and scan key areas of document and store only that information, thus saving you valuable storage space;
• smoothing -- reduces the extremes of a line art image for a cleaner, more readable image;
• ball point pen mode -- compensates for varying reflective light characteristics of ink;
