The K36 is a smart and professional camera scanner with the laser positioning guide feature for desktop and laptop using the USB connection. With its unique dual-lens design, it allows scanning the A3 and A4 documents by switching the two lenses. Along with these great features, you can use the bundled OfficeCam scanning software with this scanner to get great results while scanning books. For example, it can automatically digitally flatten curved pages, erases fingers from the scanned photos, repairs the damaged edges of documents, purifies background, rotates pages based on text orientation, and automatically splits the both-side page into the separate image file. besides, you can use the embedded OCR feature to convert a batch scanned images into a searchable PDF or editable Word, Excel, Text, and audio (Text to speech) file formats.
