DS-640 Compact Mobile Document Scanner, (Model: DS640)

Super easy connect and start scanning. Great form factor easy to bring with you. Doesn't get jammed easily, I even use this to make janky images by pulling the paper while it's being scanned - doesn't bother the machine too much. Only says jammed when the paper stops, so long as it's flowing through it doesn't stop. If there is a jam it is easy to clear. This is not a pocket wand that you can scan any surface. It is strictly a portable document scanner and a good one at that. the brother app is easy and intuitive to use; you can make full multiple page pdfs in minutes. I can't really attest to the durability as I haven't really put it through the wringer in this department, but it feels like I could drop it a few times and not hurt anything.

Works absolutely great, so easy to use we don’t even keep it out on the computer desk. Keep it in a drawer and just take it out when needed

Love how sleek & easy it is to use. I love how you can add a page & keep the whole document saved as one instead of separate pages. It did prompt me to download extra software, do NOT download the unnecessary software, it created spam problems.

I was excited to receive this. It has been an up and down experience on day one. It wasn't a plug and play product. I had to download the driver and then 2 additional applications to use it on my Mac mini. Not terrible. I got it working and was super pleased with the compact size and how easily it scanned items. The software wasn't terrible either. Then, as I started to attack my receipt pile, I came across 2 annoyances that might have me return it. The first, the "start/stop" button doesn't actually start or stop. You have to control it from the computer. It will also shut off after a while and then I hit the button and it blinks red and takes a few times of cancelling the error in the app before it starts working again. Tolerable for the price point. The second part that is irritating but also doesn't happen that often is, for longer receipts, it stops and claims there is a jam. There is no jam. I tried it several time with a few different long receipts. I ended up having to cut off part of the receipt to get it to work. That was annoying because I also had to do some trial and error about how much I was cutting off so I had to scan it 3-4 times before I got it to save a file. I like the small size so that it doesn't take up much room on my desk and it will travel well, if needed. I don't know if I love the quirks for the price. I will see after this week. Hope this was helpful!

I purchased this scanner about 2 and a half years ago and it continues to work flawlessly... This is impressive as I admittedly purchased this portable on-the-go scanner for a very different task - to digitize all the documents in my filing cabinet from the last 30 years. The initial wave included around 5000 documents soooo no question it has paid itself off. To be honest, at this point, there isn't much I haven't tried feeding through this thing - credit cards, sparkly greeting cards, supplement cardboard box packaging, etc. so I'm continually impressed it hasn't broken. When theres an issue (feeding documents too quickly, a paper jam, etc) the indicator light blinks red and, as far as I know, to remedy this you lift the top portion and close it... I've had to do this many times (which is not to say it malfunctions often) but each time it sounds/feels like the act alone should break the thing. The only bummer to me is the scanning length limitation. While the width limitation is a given due to the physical dimensions of the scanner, the documents are fed through and each individual scan is limited to around 14". That is, it stops feeding through at a certain point and if the item hasn't cleared, you get the red indicator light and the image isn't processed. Other things I like: + the cord is detachable + I was able to download and operate the supporting software on my dinosaur 2011 mac air + the software has a continuous feed feature to scan multiple documents in a row (without having to interact with the software between pages)

As other's have mentioned, this scanner can result in frequent blue screen events. When it does work, it scans well. I scanned a total of 3 documents, each time, I experienced a blue screen on Windows 11. What happens, is that if you leave it connected after the scan, Windows seems not to like that, and retaliates with the dreaded blue screen. And that's only about a minute or so after you scan something, so if you have another sheet queued up to scan, you'll be out of luck. On the third instance of this, my machine complained badly after the blue screen, and on reboot, went into safe mode, and took a few minutes to boot, when normally it boots in about 20 seconds. Pros: 1. Scans well if you can get past the blue screen that frequently happens. 2. The resolution can go quite high, but it's finicky and makes you change other settings each time you scan. 3. It's fast and impressive 4. It's compact, easy to tuck out of the way into a desk drawer 5. It would be almost perfect if not for the blue screen issue. Cons: 1. Tends to blue screen on Windows 11, as others have mentioned. 2. The On/Off button is sensitive and finicky Overall, this device is completely unacceptable, I did not find any fixes or upgraded drivers on the Brother site. I purchased this scanner, but tucked it away, still in it's box for while before using it, so the return window has closed. $100 is not a lot for a scanner, but still, that's a nice chunk of change to loose on a defective item. I intend to contact Brother and request a complete refund, siting the multiple mentions of blue screen events here on Amazon. I'll update this post as that process proceeds.

Love this thing. Just Worked out of the box. Have used it on three different computers and it worked with all of them. Scan quality is not super or anything but it is more than adequate for even professional use.

LOVE THIS! BEST THING IVE EVER BOUGHT! Connectivity was easy , software super easy to download and use , quality is great , if you don’t have one you definitely need to get one!

Su relación calidad - precio es muy buena. Por lo que se paga no se puede exigir más. Es un buen escaner, lo hace a color y con buena resolución. Es un poco incómodo tener que escanear hoja por hoja y no poder tener un alimentador que permita escanear varias hojas al mismo tiempo, pero al final cumple con su función. Es muy ligero, no pesa mucho. Muy practico de transportar y muy fácil de usar. Para trabajos sencillos, muy bueno

Good replacement for my flat bed scanner. Easy to setup (just connect cable) and takes very little space on my desktop. Document feeding takes a bit of practice and can be difficult if the document is not flat.

Ótimo e prático

Works great, small and easy to use and very fast too.

Decidí a comprar éste escáner ya que la marca en sí, es garantía; y no me equivoqué. La calidad del documento es muy buena y lo hace en cuestión de segundos :) Yo requiero escanear documentos en tamaño legal y este escáner sí lo hace. 10 de 10
