How to install Brother DCP-7040 on Slackware

I have studied quite a few web pages on installing Brother on Linux. These are some of the web pages that I studied:


Brother DCP-7040 includes a printer and a scanner. I was able to set up both the printer and scanner on Debian. Also, I have installed and set up the printer on Slackware. But setting up the scanner on Slackware has been a challenge. At the end of this article, I will state my questions about the scanner.

These are the steps that I took to install and set up the printer:

1) Start CUPS service:
chmod +x /etc/rc.d/rc.cups
/etc/rc.d/rc.cups start
2) Download the lpr and cupswrapper (rpm files) from
3) Change directory to where the downloaded packages are, and use the utility rpm2tgz to convert the files to tgz format:
rpm2tgz brdcp7040lpr-2.0.2-1.i386.rpm
rpm2tgz cupswrapperDCP7040-2.0.2-1.i386.rpm
Equivalently, it might be a good idea to type: rpm2tgz *

4) Install the tgz files using installpkg:
installpkg *
5) Add the Brother DCP7040 driver by applying this command:
6) Open http://localhost:631 in your browser, and add printer using the correct driver (Brother DCP7040).

Good news: Printer worked!

Bad news: The following steps did not lead to scanner working.

7) Download the rpm packages for scanner from
8) Change directory to where the downloaded packages are, convert rmp packages to tgz format using rpm2tgz:
rpm2tgz *
9) Install the tgz packages using installpkg
installpkg *
10) Change directory to /usr/local/Brother/sane and run
./setupSaneScan3 -i

11) Edit /lib/udev/rules.d/80-libsane.rules
(Add the following two lines before the line "# The following rule
will disable ..."):

# Brother scanners
ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"

12) Change directory to /opt/brother/scanner/brscan-skey and run

As mentioned, scanner still does not work.

When I type in sane-find-scanner, no scanner is listed. All lines that appear are commented out.
When I press the Scan button on the xsane interface, it says "Failed to start scanner: Invalid argument"

My questions:
1) Any recommendations on how to install and set up the scanner?
2) As mentioned, the scanner and the printer are in one box. What is the
device name for such a scanner?

Did you see this when you were searching for web pages?

Some thoughts on your scanner installation.
Brother devices add an entry to your /etc/sane.d/dll.conf. Is this present? ( Try 'grep brother /etc/sane.d/dll.conf').
# Brother scanners
ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"
That entry does not look complete. There is no entry for idProduct. Something like this would be expected.
ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="01ea", MODE="666", GROUP="scanner", ENV{libsane_matched}="yes"
The idProduct would need to match that of your device.

Does 'scanimage --help' show an available device?
