I absolutely LOVE this scanner!It's very easy to use, great quality of scans, and compact so I can slip it in my laptop bag and take it with me!Scans are quick and clear/clean!

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 impressive4. It's compact, easy to tuck out of the way into a desk drawer5. 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 finickyOverall, 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.

I recently purchased the Brother Scanner, and I am extremely happy with my choice. It is fast, efficient, and easy to use. The setup was simple, and the scanning quality is clear and sharp. It works smoothly with both documents and photos, making my work much easier. The automatic document feeder is a great feature, saving a lot of time.

This product is fantastic! It’s compact, making it perfect for easy storage or travel, and incredibly straightforward to use. Despite its size, it works great and gets the job done efficiently. I appreciate the thoughtful design that combines convenience with functionality. Highly recommend this for anyone looking for a reliable and hassle-free option!

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.

I love this scanner! Set up on my laptop was a breeze. When I have a stack of receipts or papers I want to process (or even 1 or 2) I simply plug the scanner into my laptop and start scanning. You get a file folder that you’ve set up with a list of scanned images. You open an image and save it where you want to under whatever name you wish. I have 12 file folders for the months in 2024, and as I scan a receipt, I name it with the date and the company and the dollar amount and save it in the appropriate month’s folder. Example - 2024-11-19 Safeway $43.19. Then I pitch the paper copy. Come tax time, I can locate any receipt I need quickly. I also use the scanner to save copies of warranties, manuals, etc., - especially the directions from packaging for products I’ve purchased or received as gifts. It’s so much easier finding them on my laptop in a file called “Manuals” than hunting through drawers of miscellaneous paper. The scanner is simple to use and understand. A few times the paper/receipt has jammed. All it takes is opening the top of the scanner and closing it, repositioning the paper and pressing the button to scan it again. VERY user-friendly. And it’s compact and light enough to take on trips and scan receipts, souvenirs, tickets, etc. as we travel and not have to lug all the paper piles home with us.

For those of you on the road and travelling - this is a game changer with the laptop. Already used it at home - love the interface and scans smoothly. So glad I bought it !! Would buy it again

Isso sim é praticidade e eficiência.Scanner com preço justo, leve, eficiente, rápido e prático.Vi antes da comprar em alguns comentários que a leitura era lenta. Sinceramente, quando chegou, umas das coisas que mais me surpreendeu foi a velocidade. Convenhamos que não vamos esperar uma velocidade de produto que foi feito para escanear mais de mil folhas dia.Recomendo a compra do produto!Agora é esperar 1 ano para nova avaliação.

So, let's start this off by saying one this -- Yes! The DS-640 is a great scanner... HOWEVER.. It does have some issues that bring it down a peg or two..I'll start this off by highlighting the positives --It's portable. It's easy to use. It's lightweight.On the downside --It's infuriating after scanning only a few documents that you're told "OH NO! We're out of memory!" .. The first time it happened I stared at the message on-screen and thought to myself.. How the heck can it be out of memory when I have 64 GB of high-speed RAM in the computer... Then I remembered that the chips inside these scanners have temporary memory built-in... but then the kicker... ...buuut I only scanned TWO PAGES... They were 3 color (black, blue, red) documents and standard paper size. It's not like it was a full-size poster in crisp detail at maximum resolution, bitrate, with edits... This was a major failure of the design, and was actually my first experience with the scanner, which as I don't need to mention, is NOT GOOD! A terrible look for the BRAND, as this was my first ownership of their brand's product, and not good for the future of this little new device sitting on my desk with the threat of return, due to a degraded trust in the product. If it's going to fail me on day one, what's it going to do on day 365?That brings me on to my next quarrel with this device. Resolution and color limitations by size. If I want to scan a sheet of paper at the fullest-size available for this device in the MAXIMUM allowed quality (resolution and color and bitrate), why am I limited from doing so by software? We physically know the scanner can do it, because we can do it with other smaller sheets and the compliance with the HARDWARE is there... but for some reason, I get rejected by software when I want to actually use the product to its fullest potential, hardware wise.With auto document sizing set to "On" you can only scan stuff at a resolution of 300x300 dpi, regardless of being set to black and white or full 24-bit color.The device does have a slider to control a guide for paper size, but it's so flimsy and loose in the track that even if a document does start to kink to one side, it's pushing that guide out of the way. No sense in even having it there, really.The port on this scanner is not a generic connection, and requires a dedicated special cable to hookup to your PC by USB, so don't expect to be able to head down to your local PC repair shop and snag a new cable after your pet gerbil decided that the big thick black cable looked like a delicious after-dinner licorice dessert.With all this in mind, choose carefully.If you're using this to scan documents in an office setting, it's fine, I guess. Just be ready to scan that 43-page packet 5 times over until the software quits telling you that it magically ran out of memory.If you're using this to scan photos, whip out the old handy-dandy ruler and be ready to fight with size-presets telling you that you can't use the fullest scan quality on auto-sizing.As the package says -- Be sure to save your box and packing materials, in case you do ever need to send the unit back in for service or repairs. I recommend buying a wet/dry scanner cleaning kit.

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

Assumes that power from your notebook is only located on the left side of the computer. USB is on the right side of the device. Aside from that, it is quick, responsive and the one tap shortcuts to folders on your computer are a dream to set up and operate. Recommended.
