Product Overview

I recently had the opportunity to use the VIISAN S21 Large Format Book Document Scanner and I am very impressed with the quality of product. This scanner is designed for large format documents such as books, journals, manuscripts, newspapers, and maps and it delivers exceptional performance.

The VIISAN S21 scanner has a 23MP Super High Resolution Output of 5504x4128 Pixels which allows you to capture highly detailed images. It also has an adjustable A2/A3 design with a 90 degree foldable hinge which makes it easy to scan large documents. The scanner also comes with a smart device application that is designed to help get great results while scanning books. The software can automatically digitally flatten curved pages, erase fingers from scanned photos, repair damaged edges of documents, rotate pages based on text orientation, and split double pages into separate images. Additionally, the embedded OCR feature lets you convert all scanned files into PDF or editable Word/Excel/ePub/Txt files.

The S21 also features built in three level LED light control which helps you take clear photos even in low light conditions. It is also UVC/UAC compliant which means you can use it for video conferencing and remote meetings with third party video conferencing software. Lastly, this scanner comes with a one year warranty from VIISAN and tech support team that is ready to help whenever needed.

Overall, I highly recommend the VIISAN S21 large format book document scanner for anyone who needs high quality scans of large documents such as books and journals. It delivers excellent performance while being easy to use and highly reliable. It is an ideal choice for anyone who needs accurate scans of large documents without compromising on quality or performance.
