Brother DS-640 vs DS-740D – What’s the same?
Type & Handling
The Brother DS-640 & DS-740D are two sheet-fed scanners where you can load sheets of paper and the machine will automatically scan them for you. Both use very little desktop space and you can manage all your settings from your Windows, Linux, or macOS device.
Speed
Both scanners have a top speed of 15 pages per minute, which is more than enough to give you clear image quality in less time. You can also increase the speed by scanning in black and white mode or using a lower resolution for the documents.
Resolution
The optical resolution of both Brother scanners is 600 dpi, which provides clear images of documents on your computer. You can also increase the resolution up to 1200 dpi with software that can really improve the color and image scanning quality of the device.
Duty Cycle
With both Brother scanners, you can scan more than 100 pages per day. However, we do not recommend going over the limit as it can actually decrease the product life. So, if you need more duty cycles, you should buy another device from the market.
Capacity & Controls
Both scanners are available with a single sheet capacity. Due to a very small size, there is no space to store the pages, so you have to submit each page manually and wait for the process to complete before launching another scan. For control, you get a simple on/off button on the front panel.
Interface
The Brother DS-640 and DS-740D scanners are equipped with Micro USB 3.0 so you can connect them to a computer, laptop, or other devices. There is also a micro-SD card slot for scanning and saving images directly to it.
Battery
Yes, the Brother DS-640 and DS-740D come with a lithium-ion battery built into the scanner. The charging time for each device is 2.6 hours, which can help you scan anywhere and anytime, even without electricity.
Warranty
Brother promises to repair or replace the scanners if you receive a defective piece that does not work or got broken during shipping. The warranty cover is over two years but you have to keep the warranty card safe to claim returns & repairs.
Brother DS-640 vs DS-740D – What’s so different?
Design & Build
The two Brother scanners may come in the same color but they have many design variations. On the DS-640 there is no trey on the back so the pages go horizontally through the system. However, on DS-740D the pages are fed vertically and come out flat. The DS-740D is also heavier and comes with a bigger frame than the other option.
Duplex Scanning
Two-side scanning is another feature that Brother DS-640 does not have and you only get it with the other option. To scan pages on both sides you have to manually turn them around and run the DS-640 again. However, on DS-740 you can just select the duplex scanning option and the device will automatically do the work for you.
Power
When comparing the power of Brother DS-640 and DS-740D we found a minor difference. Both scanners run on a 5-watt USB 3.0 cable and you don’t really need an extra power supply to manage them. But, the first device uses 2.3 watts of power while the second one takes on average 2.9 watts.
