Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I wonder if 'vuescan' supports brother better, i just today bought it for my old hp 5370c which is detected by sane but it has never been able to handle it correctly. Vuescan demo is also on slackbuilds.
I tried these commands by replacing them with brother4:bus2;dev3 since im using USB, and both give me 37 bytes files each and output the following in terminal:
scanimage: rounded value of br-x from 215.9 to 215.88
scanimage: rounded value of br-y from 355.6 to 355.567
I don't know what that means. Also, not sure this matters, but i'm logged in as root in Slackware, as opposed to just a regular user in Ubuntu. So, i do not get the root warning prompt from XSane to "Continue at your own risk" in Ubuntu.

Vuescan does list MFC-J870DW as supported on their website. Ubuntu has Simple Scan too, but i think that is based off XSane.
I just bought a Brother MFC-L2740DW and have similar problems as everyone else is reporting. Printing is easy.... it just works. Scanning is not easy. Under Mageia 3 I loaded brscan4-0.4.3-0 and ran "brsaneconfig4 -a name=brother model=MFC-L2740DW ip=192.168.1.50" and xsane can see it and scan from it fine... as long as I don't choose color. There is only one color option- "24bit Color[Fast]" and if that is selected, Xsane 0.998 will simply die after the printer starts sending data. No error message, no core dump, just "poof". Same result if I switch to a USB connection (had to add the USB ID). All the non-color modes work fine (and as a bonus, one-pass-double-sided works in gscan2pdf !!)
Using my Fedora 20 laptop, if I connect with USB and load brscan4-0.4.3-0, it works fine in Xsane in color (I don't recall what the color profile name is, however). And I didn't get network scanning working on that laptop for some reason (and didn't put much effort into it).
I updated the firmware on the printer to the latest (D1410031627 1.01 B1407141000) (you can do this on the web interface automatically!!!) and it made no difference.
Called Brother to complain about the fact that the Brother "Linux" page doesn't list *any* MFC-L model as supported or which drivers to use and that you can't even get to recent versions of brscan from that page either (the one they keep pointing people to; I had to search around for 30 minutes to find it offered for a DIFFERENT MODEL PRINTER on one of their pages). Of course, 20 minutes later and three transfers and I just get the "we don't support Linux over the phone or chat" crap. Thanks, Brother. This is my first Brother device and I bought it because of recommendations about good Linux support. I now question that... but that is a different topic.
Anyway, I will be upgrading to Mageia 5 when it comes out in a month or so (I skipped upgrading to 4 since I don't like upgrading often) and hopefully that will give better results (like Fedora 20 did). For now, I set up the network scan-to-ftp feature and that does work great and will hold me over (the printer can even generate PDF's!). Other than the above scan issue, I am impressed with the device so far. I do wish it had gigabit instead of 100-base, and that it had a usb port for scan-to-usb-device and print-from-usb-device.
