This is a used PFU ScanSnap S1100 document scanner. It's a very compact scanner, about the size of a wrapped box. It connects to a PC only, is powered by USB (no batteries required), and does not support Wi-Fi. The resolution is 600dpi, full color. As shown in the third photo, the total number of scans is 607. The items for sale are the scanner body, USB cable, instruction manual, and included CD-ROM. For the app, please use the latest version of the ScanSnap Home app from the PFU website. Although it's a product from over 10 years ago, it can still be used with the ScanSnap Home app. I was using it in a Windows 11 environment until just before listing it. It is operating normally at the time of listing, but due to its age as a used item, it is being sold as junk. Please purchase if you understand that it is a used item and are satisfied with the current condition. It will be packaged with air cushioning and shipped via Takkyubin (courier service).
