PC.Before you scan, be sure to look at all the features under All Settings to be sure you have chosen the appropriate options in order to get the best quality scan

We bought a DS-640 to do scanning of documents while we worked from home

Great scan quality

It’s also really great because I don’t have to launch a scanning software, I only have to turn it on, put in my document (size hasn’t mattered so far!), and push a button to get scanning… bonus!I also like that I can save to either an image file or pdf

Hassle free scanning right at home

It will start a scan and freeze with a connection error 9 out of 10 times

Hassle free scanning right at home

If you can put up with the other quirks (I can't), it could be serviceable for scanning things like legal documents or invoices that aren't really affected by scanning artifacts like photos are

Compact, fast, clear scans!

With smart phones so good today, these scanners now only provide benefits for finer scans, where the image needs to be flat, cropped well, etc.overall, great product, competitive price...

So easy to use and super fast scanning

Works well scanning business

It has good scanning quality with fast scanning with many different size documents.

Once you get past the initial aggravation, this is really a nice device as it does both sides of a document and the scans are sharp

Software is easy, pretty much 1 touch scan
