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

The quality and ease of using this product was surprising. I frequently scan newspaper articles, and they rarely fit on a flatbed scanner. Thus, I had to use Photoshop to stitch together 2-3 scans of the articles, which took considerable time. This scanner will handle A2 size paper, which is big enough to capture all major newspapers (e.g. Wall Street Journal), is easy and fast to use, and delivers crisp clear optics. It even has its own source of lighting. Excellent buy, and I rarely take the time time to rate products.

I'm very happy with the scanner for the price, but the software is a little difficult to use at times. Professional scanners are usually much more expensive, so this does the job without breaking the bank, but it does require a little more manual editing sometimes and it takes some getting used to. It's great for scanning flat images, but books can be a little challenging. I like that it takes high quality images and supports OCR. It has different settings for color, export file types, and works pretty well at eliminating the curve on scanned books.

Had been searching for a while for a high end, but affordable scanner for my 16 x 20 paintings. I have attached one of the scans. Beautiful. The light on the scanner is best used with no additional lights in the background. You get the best scan.

I was searching for something to replace my old 11x17 flatbed scanner that is no longer supported. I had my doubts when ordering this product, but I was pleasantly surprised. You have to be very careful about making sure you have good, even lighting, and you have to be careful about aligning the sheets consistently, but the results are quite acceptable. This would be a good product for someone trying to scan large maps.I am going to buy a plexiglass sheet to hold the papers flat, but that's the only change I'd make.

I bought this to scan vintage catalogs and the resolution is really terrible. In addition the arm has a tendency to fall just a bit and it takes things out of square. The most annoying thing is there is no catalog or owner’s manual to tell you how to adjust the brightness saturation.etc. There is a place to do that but no clue how to make it work. There is also several resolution adjustments but with trial and error I am still not getting it. I have thrown away the packaging otherwise I works return this turkey

Honestly, I expected this scanner to be better than it is. Specifically, the tiny light embedded in the overhead arm is laughable. It does not have enough light for a great image, and it is horrible if you are scanning any glossy surface. I did purchase two lights to augment the existing scanner light. The software works ok. The book flattening works if the page is mainly flat, to begin with, but not so well with a bowed page. The software is easy to work with and intuitive. I haven't needed to contact any help or support, so I can't comment on that. With all this said, I will continue to use this scanner without expecting flatbed results.

I've used various strategies to capture documents and books and I was initially attracted by the 23MP density and large-format scanning. Sadly, the device will not render text with sufficient clarity to take advantage of the sensor size and produce good OCR results; rather, I could get better OCR using my phone or my M4/3 camera. I will be returning this scanner, as it fails at the one job for which I really needed a dedicated device:It's unsuitable for digitizing my personal library of textbooks and literature. If the device's light is off and I use an oblique source of illumination, there is too much noise in the image, not enough contrast. If I increase the ambient lighting or use device's light, I get washout and/or glare that makes texts unreadable. Something in the automatic light sensing and exposure-adjustment either needs refinement or the components are simply not up the task—there is nothing in the software that is available to the user to manually adjust things like focus or exposure.

Great for high quality A2-sized scans. Software is easy to use
