Brother DS-640 vs Epson DS-70 – What’s the same?

Type & Handling

The Brother and Epson scanners are portable devices that take up very little space on your desk and help you turn any document into a digital one. You get a sheetfed paper handling system that requires you to manually load each page to be scanned.


Both scanners are available at a decent 600 dpi resolution for the price. You can scan color/black and white images and documents to get clear digital prints on your computer. The resolution of both scanners can be increased up to 1200 dpi via software functions to take full advantage of their values.


Because both scanners are portable and light, there are no input or output trays to assist you with bulk orders, and you can only scan one page at a time. If you need to scan multiple pages at once, consider choosing a more powerful scanner on the market.

Light Source & Image Sensor

To allow you to scan at maximum performance, Brother and Epson scanners are available in all three lighting options. A full-size CSI image sensor is also installed there to provide users with high-quality images and better legibility.

Controls & OS

The scanner comes with a simple start and stop controls that any user can easily understand. Plus, each device supports Windows, macOS, and Linux OS, so you can manage your device in any environment.

Brother DS-640 vs Epson DS-70 – What’s so different?


Brother and Epson scanners may look the same with white colors, but there have been a lot of changes in design and overall build. The Brother mobile scanner is much larger and weighs twice as much as the second scanner. So, Epson would be a much better choice if you have a job that requires you to travel constantly.


The scanning speed of the Brother DS-640 scanner is faster as it reaches 15 pages per minute while the Epson mobile scanner speed remains at 10 pages per minute. This allows Brother to scan faster and cover more pages in less time.

Duty Cycle

Surprisingly, the Epson DS-70 has a duty cycle of 300 pages that you can scan daily, but the Brother only has a capacity of 100 pages per day. So people who get more scan requests per day can choose the latter option.


To help you connect the scanner to other smart devices, Brother provides you with Micro USB 3.0 and Micro SD cards options. While the Epson DS-70 is only available with USB 2.0 on the back panel. So, you get faster speeds and more connectivity options by choosing Brother as your daily driver.

Wireless Options

Moving on, Brother has a Wi-Fi-enabled scanner that lets you connect wirelessly to your home or office and manage all your work from any device. Unfortunately, this feature is not available on the Epson DS-70, so you have to use a wired connection to save your scanned files.


A lithium-ion battery is another item included only with the Brother DS-640 to allow you to scan without power. You can charge your device at any time and take it anywhere to scan any document with no connection.


Speaking of power, the Brother DS-640 consumes slightly less at 2.3 watts, while the Epson scanner averages around 2.5 watts. Also, there is no sleep mode on both devices, so you have to turn off the scanner when not in use to save power.


A warranty helps customers receive an undamaged product, which is why both scanners come with one. However, you get only a two-year warranty with Brother, whereas Epson scanners come with a three-year warranty.
