VIISAN Large Format Book & Document Scanner, Capture Size A2/A3, 26MP USB Document Camera with Auto-Flatten, Fingerprint Removal Technologies, Multi-Language OCR, Compatible with Windows & macOS

I needed something to scan all of my college notes in to my computer easily and this works as expected! Super easy to use and super easy to set up. The performance and quality of this is amazing. I am forever grateful!

The museum I volunteer at purchased a Viisan K21 scanner. It was so much faster that we opted to get a second Viisan scanner. The S21 is an even better fit for some of the projects we need to do, like digitizing early newspapers. The K21 was at least ten times faster than what we were doing. The other volunteer using the S21 said it was even quicker than the K21 and could cover larger documents. He said that it scans as fast as you can put the piece of paper down, remove it, and put another one down. Another plus. It doesn't have the scanning sound that our Epson scanner makes. The other volunteers in the work area couldn't handle the noise; we didn't scan when they were there. So now, we can scan without driving others crazy.We initially had problems getting the software to execute properly. I emailed the Viisan help desk and quickly got a response that they had just published a new version. Once we downloaded that, the S21 worked well. The image quality is good.Some hints. You can only use one Viisan scanner at a time. There are some limits on the file naming pattern you can use, but we easily get around by renaming with free IrfanView software.A friend who has many family history papers got one based on our recommendation, and she loves it. Her great-grandson helped her set it up, and they did a whole archive box in an afternoon.If you have a lot of papers or photographs you wish to digitize, the S21 is well-worth purchasing. We started working on eight full file drawers of papers and wondered if we would ever get them done. But, with the Viisan scanners, we'll be done in a couple of months, not the years we were looking at.

Highly recommend. - Not a traditional "scanner" but an overhead high resolution photography 'scanning' device. You need some basic lighting (I used GSKAIWEN LED Video Light Battery Powered Photography Light Portable Handheld Wands -- available on Amazon) knowledge and equipment. The lighting on the scanner itself doesn't work well for most items - especially anything reflective.Overall I scanned newspapers, family scrapbooks, Bibles, objects of all manner (childhood toys, awards, diplomas, etc), and am extremely pleased. - Quite high resolution, and can easily zoom in and read every word of a document.My use has been mainly digital archival of family mementos for long-term digital safe storage.

The document camera worked OK for a week or two, then couldn't connect to PC. I double checked the only USB 2.0 connection and the light that works with the device lite up. Not can't use.

I did a fair job on pictures, but I had to raise them closer to the camera to improve quality. Scanning documents using OCR was great. Scanning books was not the best. Some pages had gray rectangles that blocked out some of the words or pictures on each page, but not every time. Not sure why?????

It is a super professional scanner that scans texts, photos, maps, photos, books, etc., all in a professional way! For example, it can automatically digitally flattens curved pages, erases fingers from the scanned photos, repairs the damaged edges of documents, and automatically splits double-page into separate images. Easy to assemble, built from top quality material. The program that is installed on the computer to carry out work is easy to use, very intuitive. Good quality-price ratio.

Software offers many configurations. Very portable. Able to digitize A2
