    This little dude is super compact, does exactly what it says, and is perfect for scanning documents or receipts for your records. I’ve been juggling a ton of legal and medical paperwork while traveling constantly, and this thing has made it so much easier. Honestly, it’s better than the big, clunky all-in-one printer/scanners back at my office. The Brother software is surprisingly decent too—clean interface, no fuss. And unlike the compact Epson scanners I’ve tried, this one actually works. It’s earned a permanent spot on my desk at home.

    Style: New Model: DS640Verified Purchase
    I bought this scanner because my Epson scanner that was in a checked bag got lost. Decided to give this a try. This is by far a better scanner than the Epson for this product class. I have to scan business documents on the go and this Brother's scanner has really high quality scans. It scans at 300 dpi but the scans look just as good as my office's thousand+ dollar flat bed scanner that scans at 1200 dpi. (Epson's website markets their product as 1200 dpi but the software never lets you go above 300.) Even at 300 dpi, the scans on the Brother's scanner will still save at around 11-12 MP per page at the highest resolution--way more than I need. The build quality is better than the Epsons too. The software is really intuitive and I had no problem transitioning over.

    A couple things I've noticed. There is a firmware/driver update on Brother's website for this scanner that won't install on my computer. It's not a big deal to me because the scanner does work great already without it. Lastly, the scanner doesn't do as well as a flatbed scanner for archiving children's artwork that has artwork glued to it. It's still 5/5 because this scanner isn't really meant for that. Needless to say I'm going to get a Brother's flatbed scanner for that purpose because this one has far exceeded my expectations!

    Edit: After about 300-400 scans, there's a black line that appears on the scans. Other reviews have the same issue. There is a notch on the scanner that detects when there is a page inserted and holds the page. It looks like this notch is a mechanical issue and not an easy software fix. This isn't a big deal for me but if you are using the scanner for archiving purposes it might be a deal breaker to have this line.

    The best feature about this device is the single-click presets, which allow you to customize the quality, file size, and save location, as well as color, grayscale, or black and white.

    Make sure you really have use for a document scanner. It takes 7 seconds still to scan this, compared with the 10-14 seconds of traditional scanners. Keep in mind that if it is just for your own use, you can use an app on your phone like genius scan to capture scans for even less time than this. The file size will be larger, but you can use another software to shrink the file after that. 2mb vs 700kb, basically. The benefit to this is that the lighting will always be the same, and it will be fewer steps. But phone pictures' quality will be about the same.

    Get this if:
    -you travel a lot
    -need the space
    -have a lot of items to scan
    -you like the satisfying sound of scanners

    You can choose for it to scan between 100dpi and 300dpi at increments of 50, and you can choose from 5 notches of file size (quality).

    It goes to sleep and you have to wake it up if you walk about for around 20 minutes. Haven't looked into if I can change that yet.

    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.

    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

    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.

    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
