Brother 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.

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.

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)

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.

Easy to set up , go to website , pick your scanner and follow prompts . had it done in under 20 minutes very easy to use and well worth the time and money ... compact and easy to store .

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!
