Brother DS-740D Duplex Compact Mobile Document Scanner (Renewed Premium)

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

This is a nice little duplex scanner. I bought the factory refurbished model, and for a quick minute I thought that might have been a mistake. After every page, the scanner took 20+ seconds to be ready again. I'm using Linux (Fedora), so I thought maybe it was a driver problem. Or maybe I got a dud unit. I watched the udev monitor and realized the scanner seemed to be power-cycling after each page. Odd. Turns out, it was the port on my laptop. I plugged it into a different USB port ON THE SAME LAPTOP and the scanner works great! No long delay between scanning subsequent pages. No strange udev messages. Linux folks, Brother has Linux drives on their product support website (*.deb and *.rpm). Install is simple. I used Gnome's "Document Scanner" at first as the scanning front end. You have to select "All Pages From Feeder" (not "Single Page") in order for the two-sided (duplex) functionality of the 740D to work. You MUST ALSO select "Both" from the preferences dialogue. I eventually switched to "gscan2pdf", which is more flexible in terms of scan post-processing. In the "Scan" dialogue on the "Scan Options" tab, the "Scan Source" option allows you to perform two-sided (duplex) scanning. Select the option ending with "left aligned" for single-sided and "left aligned - duplex" for two-sided.

Ya tengo más de 3 años y sigue operando muy bien

Rapidisimo y comodo de usar. Como es portable lo puedes llevar con la laptop y escanear lo que se te ocurra. Tiene gran resolucion y es MUY facil de manejar. Mejor compra que he hecho!

So I bought this (factory refurbished) because my dad passed earlier this year and he was a pack rat; one of those people who prints out bill payment confirmations and all kinds of random papers, not to mention the countless photos he had. Anyway, I figured this scanner would help with getting everything onto a computer much more efficiently than my printer/scanner combo. Here's what I found: -Brother has their own software to update the firmware and can manage your scans. This software does NOT work on my desktop however it DOES work on my laptop. My desktop is a high-end gaming machine that can run circles around my laptop without breaking a sweat, the difference is that my desktop has an AMD Ryzen 9 processor whereas my Dell G7 laptop has an Intel I7. My desktop just does not recognize the scanner when it's plugged in. So, I have to use 3rd party software, which I've managed to make work pretty well, but is disappointing that this is even an issue. -The top lid flips up so you can have photos/papers come out straight up instead of behind, however this does not work well with photos. While scanning pictures, the photos would move while going through the feeder causing a warped image being scanned in. So this feature works well for papers, just not for photos. -Portability? Yeah...not really. I had planned on taking this to my dad's house and scanning things there, but the issue is that you have to plug it into a computer. I desperately tried to use it on my android phone but there just aren't any apps that will recognize the scanner and not just use the phone's camera. The "portable" terms is just literally that you can pick it up and move it around, within the confines of the USB cable length - which what they give you is only 2ft long, so you're going to need to buy a longer cable yourself. Overall, I'd still recommend it for on-the-fly scanning, especially if you have a metric ton worth of things to scan. These things aren't exactly cheap but if I had to buy one again, I'd make sure to get one that is actually portable, one that has memory and a rechargeable battery.
