Helped me go paperless

Style: DS940DW WhiteVerified Purchase

I run a business and have thousands of documents, with this scanner I can easily scan them to a digital format, either .jpg, .PDF or Searchable .PDF , one or two sides at once. Long recopts and more, The app allows you to create templates for scanning to save time and I can scan into my phone, Tablet or Laptop... It also has scan to SD card in case you just want to go somewhere and scan a few documents but do not want to drag a laptop along. You can connect using WiFi or USB... The battery lasts a long time, I have never had an issue with low battery. Easy to clean, I recommend it for anyone that travels and needs to scan when on the road. I just throw it in my laptop bag.

Perfect to digitize receipts and papers

It doesn’t take much space and can be stored in suitcase. Scan is fast and quality of image is good / customizable.

To connect the scanner to your own WiFi. You need connect to the WiFi of the scanner, figure out the IP address of the scanner, and open that in browser, login using the password printed at the bottom, go through the wizard to connect your own WiFi.

Once that is done you will be able to use it as a device part of your network.

Work on Mac and Windows.

It doesn’t have autofeeder but you can add additional page scan one at a time. So it is not for big jobs.

Good for the price

Does a good job and scans very quickly. Both sides scanning is a great feature. Only drawback is it can only do one sheet at a time, but that is just a fact not a criticism. The only problem I have had is sometimes getting it to be seen by my Mac computer. I sometimes have to unplug it and plug it in so the computer recognizes it. That is usually after it hasn't been used for awhile. However, overall, I am pleased with it.

This product is designed to be simple and is everything but that

Reviewed in Canada on October 24, 2023

Style: DS940DW WhiteVerified Purchase

I would not recommend this product to anyone.

The only reason I was able to get the item to work was through tons of trial and error and with my IT expertise. I see no way a common person can get this thing to work for them without a deep understanding of hardware and software. I have multiple Brother products, and I choose to do so even though their terrible drivers and bloatware apps because their hardware design is top-notch. This is not the case for this product, I am finding it hard to find any positives for this item.

Poorly designed physically, it does not stand up to the standards of brother products. The hinge feels like it's going to break after only a few times opening it. They put a plastic guard on one side that they did not put on the other side to balance out the product so the jam-clear opening does not close evenly on both sides, resulting in constant jamming. Item also has more than enough room to support a display instead of just LED indicators.

The product is designed to use WSP to connect to your router, even though it is designed for an office environment when many enterprise access points do not support WSP for security reasons. The software and drivers they provide are just a bunch of bloatware, I am surprised they give you so many tools, and none of them are designed to connect your item to your Wi-Fi network not even their BRAAdmin tool, and the actual scanner app they provide does not work when the Windows default one does. The only way to do so is to connect to the router as an access point login to the web interface then add your wifi SSID and password there.

The next issue is the item is meant to be transported and does not come with their marketed travel case, the item should come with the case in the box not an add-on at this price point.

The final nail in the coffin was that you cannot charge it without a powered-on computer, you can't use a charging dock, brick, or block. Use USB C instead of this odd USB cable connector that you have here.

The product is only easy to use as a connected device, which goes against its entire design being a battery-powered portable device.

Create a properly designed product if you can't get it at the sub $200 price point price it higher but please do not cut costs by cutting a proper LCD display, USB-C connector, and proper hinge design.

Works exactly as advertised and then some

Reviewed in Canada on December 30, 2021

Style: DS940DW WhiteVerified Purchase

It's a portable, battery powered scanner. It does exactly what it says it does, although I noticed a prior review that mentioned that the scanner can't connect to existing wifi networks, so I wanted to correct that.
- The scanner DOES support this type of connection through its "infrastructure mode" setting. If you look up the model number and "infrastructure mode", you should be able to find instructions to set it up in the online owner's manual (not sure about the physical manual). Long story short, you need to connect to the scanner's network, then access the scanner's direct IP address (should be 192.168.118.1), log into the web interface, and set it up in there. It's not a desktop driver setting. I set it up to use both infrastructure and direct wifi connections, so I can still connect to the scanner directly if I'm not connected to the wifi network that I set up.
- In case you missed it, max DPI is 1200x1200. Desktop driver supports 300x, 400x, 600x, and 1200x. I think it supports 100x and 200x, but I don't use those.
- The DSD... thing, is just a piece of plastic. Stays in place well when closed, but is loose when open. It also directs the output upward at a 90 degree angle, bend is roughly 3/8 of an inch or so. DO NOT USE this "feature" for items that you don't want bent!
- For scanning things thicker than paper, the scanner can reportedly handle up to 48 pt thickness. I've been scanning 35pt cards (mtg, yugioh, as well as some sports cards) with thin plastic sleeves over them without issue; rollers are rubber with enough pressure to move the card with plastic through the scanner without damaging the card features. I don't expect that any thicker will be doable though. Definitely not a graded slab, that's for sure.
- Scanner is designed to accept documents from the left side; there is a feed sensor about an inch from the left side that is used to detect the presence of things to scan.
- No tray for multi-document feeds; this scanner is only designed to scan one item at a time.
- Duplex scanning happens all at once; no need for the document being scanned to run through the machine backwards or anything like that.
- Even with all image processing turned off, I noticed that the machine has some trouble with detecting where a document starts in the case where the document is covered in plastic (like the aforementioned cards). I've got it mostly dialed in now, but originally it would either overscan slightly or underscan slightly, maybe by a margin of +- 1mm? Not a problem for regular paper documents but for scanning details of cards sometimes it misses the card edges.
- The web interface for the scanner is surprisingly capable. It's about what you'd expect from a printer/scanner interface, but there are some features that I wouldn't expect to see in a consumer scanner that are nice-to-haves for someone with more tech know-how.

Overly, very satisfied with this purchase.

Take anywhere, use without a computer.

Reviewed in the United States on March 28, 2022

Style: DS940DW WhiteVerified Purchase

I ordered a different model at first and it did not come with the micro sd card feature. Brother does not advertise well and their instructions are terrible. I look at a lot of websites to see what people who have bought the product are saying. The instruction did not say to fast press the on/off button to turn it on and did not say you have to press and hold the on/off button for 6 seconds and then let go to turn it off. Almost returned it because the lights were flashing and slow to respond when turning on and off. After figuring out that on and off procedure, the scanner worked flawlessly. I like the double sided scan feature and you do not need a computer if you are saving to the SD card. I bought this brand and model because on a government computer, you cannot just hook up any hardware and put in any software without getting approval from the IT department which usually do not allow anything they do not know about.
You would think being part of the largest organization in the State that you would have the best of everything. The exact opposite is true. I have antique hardware and am using Microsoft 2013 which was a recent upgrade from Microsoft 2003. The lazerjet printer looks like it belongs in a museum.
This scanner solved my problem. It plugs in and becomes an external drive. It scans 14 pages in 40 seconds or less. It can scan in the jpeg or pdf format. It takes up very little space on your desk and is very quiet. You can scan and save through Wi Fi, SD card, or USB cable. The utilities software is alright, not the greatest and like all other brands, they allow you a sample of the PDF software but want you to buy the full version. They make like it comes with the full version of the software but then it begs you to buy it.
The only thing is that you cannot scan a page in a book. The page you are scanning has to pass through the scanner, unlike a scanner bed which will allow you to scan an open book. Not unless you rip out the page and pass it through the scanner. I use this scanner everyday at work and it is holding up very well.
Legal documents, maps, timesheets, can be scanned and sent through your computer saving you a trip from your remote office to your main office saving you time, money, and gas. Especially with the price of gas today, you will be happy you purchased this scanner. Do not forget to buy the hard case to protect your scanner. I take my scanner where ever I go.

Small, light and can scan a double-sided page to an SD card.

Reviewed in the United States on August 2, 2017

Verified Purchase

I purchased this scanner to simplifying digital back-ups of household documents to reduce paper clutter. The battery life on the scanner is wonderful for my purposes, and the scan directly to SD card feature makes it simple to declutter without much interruption. I haven't tried using the WiFi option because the SD card is just as convenient.

The included software is workable, but not as good as commercial software like Adobe Acrobat. It fits the purpose of organizing individual scanned pages into a larger document, although it's cumbersome.

Unless the paper is lined up exactly, it tends to scan on an angle or get stuck.

PHEW!!! Difficult home wifi setup. But worth it coz scanner is FAST, COMPACT & LIGHT

Reviewed in Singapore on September 20, 2021

Style: DS940DW WhiteVerified Purchase

I was truly FURIOUS at first coz of extreme difficulty doing the wireless setup with my home network!! Then i finally figured out had to do the WIFI DIRECT pairing with my tablet first >> Then whilst still connected in this mode, click "Machine Settings" at bottom left-hand corner of app. Which opens up the Admin Portal in your browser. Key-in default password (indicated on label stuck under scanner) and Login. Go to "Network" tab >> "Wireless (Setup Wizard)" ... after that was a no-brainer. Just need your Wireless Network SSID credentials handy. And wish that instructions were much clearer from onset, plssse!!! Btw, after you're done with the admin portal, don't forget to change its default logon password for security!
