OCR Function, for Telework, with Inner Camera, Non-Destructive, Self-Scanning, Dark Gray, A3 Compatible App is downloaded. Instructions are in the manual. The manual was saved as a PDF, but I will include a paper copy. It's dark, but readable. The stand is attached with screws using a Phillips head screwdriver. The screwdriver in the photo is not included. I don't fully understand the functions, but I'm selling it because I bought a different model. Foot pedal switch is not included. With the timer (set in seconds) shooting, you can create a multi-page PDF by automatically taking photos as you replace the documents. However, that process is hectic, so I repurchased a scanner with a foot pedal switch. Therefore, I am selling this. Purchased in March of this year and not used much. The current Amazon price is 21,000 yen. It does not have a distortion (curvature) correction function for scanning books, so it is suitable for scanning single-page documents.
