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 love it. I am computer illiterate. I can barely use email. It was very simple for to get up and working, Just need to work on understanding all the cool features.

We have been using two of these overhead cameras (they are not really scanners) to photograph fragile historic newspapers. With the newspaper open on a flat surface, one camera photographs the left and the other photographs the right, each one being controlled by an inexpensive laptop. The resolution isn’t great, so during post processing we have to bump up the resolution using imagemagick. We also use supplemental lighting and turn off the built-in light. My only complaint about the cameras is the hinge doesn’t reliably open to or stay at 90 degrees. Even with these issues, the Viisan cameras offer great value for the money. They produce a better and more economical result than using DSLR cameras.

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.

I ordered VIISAN scsnnerfor multiple document processing. I had a difficult tine getting it to work, so contacted tech support. After taking me through all troubleshooting steps, it was determined the device had an issue. The support team arranged for replacement of device and the new device works without any issues. I'm still learning about device, but very happy with it. Thank you to support team. Very professional.

After spending an entire afternoon with this document scanner (it's really a camera) I decided to return it. My goal was to scan my documents and photos. This product is so so on document scanning. It's terrible for photo scanning. The image quality was unacceptable and the software, while somewhat easy to use, is extremely limited. For the cost of this device, I expected a better quality product in both hardware and software. Steer clear of this one.

I purchased this to scan books cover to cover. It handles text perfectly. When pages transitioned to black & white pics or color pages, the capture zones would get thrown off completely and I would have to manually edit the pages to bring the green lines to line up with the desired scan area. Two pics shows the green lines completely off or confused by what it should scan. I could not scan the book in one session and save the work and resumed the next day. After scanning across two days of the same book, I decided to export. I uploaded a pic showing the export results of large size page followed by a small size page which is the transition point from day one to day two. I couldn't fix. I check the resolution and it was the same throughout the saved scanning session. The other challenge I had was keeping the book centered and over time it would shift left and I would have to recenter it. I tried to keep a minimum of my thumbmail because any larger presence would be shown on the scanned page. Setting to automatic would be impractical for scanning this book since I edited over half the pages. Scanning large documents worked great. I've completed my testing and evaluation for my application. I have 38 more of the same kind of books. I want ed to get rid of them and just keep the scanned books but for my personal time and effort, I think I will keep the books and give up scanning them. I did not test on another book size or binding. I had purchased this for that specific book series because it would not fit on A3 scanner model. Book dimension opened is 19" x 11.5".

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.

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.

We had a missing part that, after contacting the seller they acted very swiftly to replace this. Then followed up to ensure it had arrived safely. The product is excellent and just as described. Would thoroughly recommend.

The image taken from this scanner is not as sharp as I thought. I have send a message a few weeks ago but no reply. Geoff G & L Services Ltd
