I purchased this about 5 years ago. There is no instruction manual. After using it a few times, it was stored for a long time. The main body itself appears to be clean. Operation has been confirmed. The mat was folded for storage, so there are creases. The back side shows noticeable deterioration, but the front side is not so noticeable. iOCHOW Document Scanner Book Scanner S5 22MP Non-Destructive Automatic Flattening A3 Size Compatible Multi-Language OCR Function USB Document Camera 【High-Resolution Scanning】 This iOCHOW S5 scanner clearly scans documents with a high resolution of 22MP.
