The S1100i can scan from business card size to A4 and with the use of optional carrier sheets can even scan A3. A4 portrait documents can be scanned at speeds of less than 8 seconds per page. In addition to standard paper types the S1100i can scan plastic cards such as credit cards or membership identity cards.

Multiple page documents can be effortlessly scanned thanks to the continuous document feeding function which allows you to insert pages one after another without any extra button pressing by detecting automatically when a sheet enters and exits the scanner. It is also possible to scan doubled-sided documents using this method. To make scanning as simple as possible, ScanSnap inspects each document to decide if a document should be scanned in black and white or colour, what the size of the page being scanned is and eliminate blank pages, all of which serve to speed the scanning operation and minimise your storage requirements.

In addition each document will have misaligned text corrected (Auto Deskew) and each page will have its orientation automatically adjusted. The scanner offers two selectable paper paths, a straight path which is suitable for photos, postcards, business cards, plastic cards and the optional ScanSnap carrier sheet, and a U-turn path which is suitable for most common office paper.
