High-Precision A3 Scanning: An A3-compatible scanner equipped with a 13-megapixel high-definition CMOS sensor faithfully reproduces everything from books to receipts. As a book scanner, its non-destructive scanning technology preserves the binding of valuable books, while its curve correction function automatically flattens pages. Whether for home use or as a professional document scanner, one-click scanning completes the process, from JPEG to searchable PDF conversion. For business use, dedicated software compatible with Windows and Mac dramatically improves document management efficiency in the office. Overhead Design: The compact overhead scanner achieves miniaturization. With a stand scanner structure, it provides stable scanning from A3 wide-size books to B4-compatible professional books. As a USB document camera, it enables real-time sharing of documents during Zoom meetings. The document scanner is designed to connect directly to a computer via a USB Type-C port, supporting high-speed processing of documents compliant with the Electronic Bookkeeping Act. The portability of the compact scanner body promotes work efficiency in a mobile environment. It can be stably installed in both office desks and educational settings. LED Lighting System: The asymmetric LED lighting system provides uniform illumination of the scanning surface without shadows. It significantly reduces reflections from glossy paper. The overhead light with 3-step dimming function enables high-definition character recognition scanning even in dark places. The plane correction algorithm automatically flattens the curvature of magazine pages, and distortion correction technology minimizes wrinkles in receipts. It dramatically improves the reproducibility of important documents. It demonstrates high-speed scanning performance, which is the secret to its popularity as a self-scanning scanner. Multilingual OCR Function: The character recognition function supports 130 languages and generates editable text data simultaneously with scanning. It achieves diverse format conversions with one click, from searchable PDF output compliant with the Electronic Bookkeeping Act to the digitization of books. In web document camera mode, OCR-processed materials can be shared in real-time during Zoom meetings. From the digital conversion of textbooks to contract management, it comprehensively supports the lifecycle of business documents. Whether for self-scanning or professional use, it can digitize everything from books to business cards with one touch. Optimized Work Efficiency: Automatic page-turning detection enables high-speed processing of large volumes of documents with continuous reading mode and batch processing functions.
