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.

fairly easy to setup.The instructions are fairly easy to follow.Good scans

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.

I recently purchased this A3 Tabloid scanner as a hail mary after my trusty Mustek A3 driver died after the MAC Big Sur update. With no ratings or reviews, I held my breath and hoped for the best. After my initial test scans, I could not be happier. *Sigh of relief*I am an illustrator/painter so I am either scanning black & white line work (to later be live traced in Illustrator) or large acrylic paintings where the resolution and color brilliance is vital. So far paintings have scanned very close to true to color (very little photoshop tweaking was needed). The black and white line drawing test needed some sharpening and contrast adjustment.Driver installation was easy to install after going through the "read me" file and to top it all off, it arrived two days early. The only con would be that the lid is not very heavy but I had my expectations set very low based on the price.

I gave this a test run using a print of a ship, not a real-photo, using their descreening utility and it worked well. The print shown above is a 11x14 at 300 DPI. After scan was done I resized to 1600 pixel on longest side. Without using the descreening utility the image looks like crap and I am very happy the tool was in the software provided with the scanner. All in all I am well pleased with the product. You do need space to install this. Installation was easy though I had to go to my DVD drive and manually click on setup to get it started.

Be sure to note the words, "WIA only support to 600 dpi"."Windows Image Acquisition (WIA) - Win32 apps | Microsoft LearnWIA 2.0 subsystem also includes a basic image processing filter driver add-on that is optionally replaceable by the scanner driver, if the driver chooses to provide a customized image processing filter."The VSCAN installation includes downloading (who has a CD drive, these days?) scanner drivers.Their tutorial specifically shows them choosing 2400dpi setting.The same application used in their tutorial (provided application) only goes up to 600.The user manual says,"The supplied Event Utility software only provide scanning resolution of maximum 600dpi.If you want to scan in a higher resolution image, you can scan within ViiScan program or via TWAIN-compliant applications."Well, I'm using the ViiScan program, and it doesn't do higher resolution.I cannot de-conflict the information available, and I cannot scan beyond 600dpi.

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."

Much needed to scan a4 pages, photos and books. I like the performance and quality. It is easy to use and gets the job done quickly
