This item is left at my parents' house. Sanwa Supply Document Camera 400-CMS012 Although listed as having no noticeable scratches or stains, it shows almost no signs of use. I connected it to a computer and turned it on just to be sure. The power lamp lights up, and the LED light brightness adjustment works fine. The mat has been folded for a long time, so it doesn't flatten easily. I installed the CD-ROM on the computer and took pictures of the front and back of a "Yu-Packet Post Mini" envelope and an ink box. Is this what 2-megapixel resolution looks like? I printed the images and compared them to the actual items. Please note that the quality of the paper and the performance of the printer will also affect the results.

I look forward to hearing from anyone who is interested.
