This is a portable scanner capable of scanning A4 size documents at a resolution of 1200 dpi. I have used it about 5 times. The protective film on the top surface is still attached, and it is relatively clean. There are no operational issues. A printed copy of the user manual is also included. - Brand: Avision - Model Name: ScanQ - Resolution: 1200 dpi - Scanning Method: OCR - Size: Portable - Included Accessories: AC adapter, USB cable, quick guide, carrying bag, microSD card adapter, 16GB microSD card
