VIISAN 3120 A3 Flatbed Scanner, 1200 DPI, CIS Sensor, Scan 11.7" x 16.7" in 8 sec, Frameless, Auto-Scan, Document & Photo & Book Scanner, Design for Library, School and Soho. Supports Windows & Mac

Very decent flatbed type scanner that is very easy to setup, install, and run. Very easy to configure its settings and there does not appear to be a lot of useless bling in the software. *The bigger size necessitates the need for its own power source. Works on both USB 2.0 and 3.0. *Download and install the drivers & software FIRST prior to turning on the power and connecting the USB cable. *300 dpi seems to be the sweet spot in terms of decent detail and speed of scan. *Be weary of (some of its software settings) the use of "dust removal" On "high" tends to be hyper aggressive and remove some words on both pictures, documents, and PDF's. If you have need to use it, set it on "low". *The more software modification settings enabled the slower the scan can take. Overall, a decent purchase for light to moderate usage. I find in much better than the Cannon Lide series, which I've used extensively in the past.

I recently got it. I tested out just to see it works. I am impressed at all the features it has. I am an artist and I needed a scanner that folds open at the short end not the horizontal sides. This will be easier to scan sections of large artwork I do to peace back together in Photoshop. I read the instructions and it is a feather where it says it can scan sections together. If this is true I won't have to open up Photoshop to piece together scanned sections of large art. This scanner is about same width as typing paper but longer then 11" typing paper. So it will easil scan legal paper. I am very impressed with all the features this scanner has. It is amazing. I hope they all work.

Bought this new in May 2022 because it advertised being able to scan photos with exact color matching etc... Purchased this to scan my art so I could make copies digitally. However, every scan looked washed out and dull, not vibrant in any way. I tried every configuration offered within it's software and no results changed. Reviews were very positive so I figured I just didn't know what I was doing. I contacted their "customer service" with image attachments to ask help in how to resolve my issues. They kept reply with "return to default settings", which was what I had sent them in the attached files. Never got any help further than that. I put it away for a long time and decided to try a new computer and give it another go 2 years later. Same results. What had changed was the customer reviews. Suddenly, SEVERAL negative reviews matched my issue without any satisfaction. After having an expert look into my scanner, it seems an overseas maker is putting out dysfunctional versions at an alarming rate and possibly uploading fake positive reviews to attract buyers. At this price, I had hoped perhaps my particular model was a bad one and considered buying a replacement. But after having a professional look into it, it seems this is not a safe purchase to gamble with. I've chosen to donate this hunk of junk.

This is a high-end scanner that is easy to use and produces great images up to 1200 dpi. Software is included on a CD or through downloading from the manufacturer. Its price argues against purchase by a casual user. It is not portable.

The installation without CD (i dont have CD drive on laptop) was simple. The scanning at the highest DPI setting works really well. The image size is massive and detailed. Im glad I finally found a scanner for my artwork that was too big to scan with the smaller Canon scanner I have. edit: updating my review. As another reviewer stated, the quality of color scans is noticeably washed out. What a drag.

I was having a hard time finding a scanner that was large enough for 11x17 scans that put out TIF and other high quality formats. I do graphite work and the scans are spot on. Software was easy to install and work with. Occasionally glitchy and needs a restart but I love it for the price.

As others have noted, this scanner does not register fluorescent colors at all. Not even their hue. Which is interesting. It comes with a CD for the scanners - who has a CD drive any more? Once I found the software online and got my computer to play nice, it was fairly easy to use. For a 12 inch bed and 1200 dpi it works well and us a reasonable price

I LIKED the overall packaging of the scanner, the size of the flatbed, the shipping packaging, and the speed of delivery. I was disappointed that it was not compatible with my scanning software (PDF-XChange Pro), that the proprietary software was a bit clumsy and outdated, that the image quality of the scanner was inferior to other scanners (with like-to-like settings) such as Canon and Epson, and that it was fairly expensive although similar products are similarly priced. After giving it a few test runs and consulting with my scanning app provider, I reluctanty returned the unit to Amazon in the orginal packaging as I received it. Amazon appropriately issued me a full refund, thank you Amazon. An unsatisfactory product partially bailed out by Amazon's customer service. I really like the product concept and I am disappointed it was not a "Keeper."
