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.

The left picture is from my Epson Photo Scanner, which is made for letter size so I have to piece my pages with an app. The right picture is my new VIISAN. The colors on the Epson match the original perfectly. I tried all the adjustments and couldn't get it any closer than this. I love the big area but I am not happy about the color problem.
