Problem with Brother scanner

[Robin Lee]

Hi list

I recently got a Brother scanner/printer for my Fedora 31 desktop. I've
installed all the drivers from Brother and the printing part works
fine, but not scanning.

When I launch simple-scan, either as root or normal user it can't find
any scanner. Although it will show up in Settings -> Devices -> Colour
on two lines, both as a scanner and a printer. lsusb also shows two
devices.

What's interesting is that at each boot the following shows up in the
logs

systemd-udevd[1103]: Configuration file /etc/udev/rules.d/65-brother-
brscan4-libsane-type1.rules is marked executable. Please remove
executable permission bits. Proceeding anyway.
systemd-udevd[1103]: /etc/udev/rules.d/65-brother-brscan4-libsane-
type1.rules:9 Invalid key 'SYSFS'
systemd-udevd[1103]: /etc/udev/rules.d/65-brother-libsane-type1-
inst.rules:14 Invalid key 'SYSFS'

The content of 65-brother-brscan4-libsane-type1.rules is as follows

ACTION!="add", GOTO="brother_mfp_end"
SUBSYSTEM=="usb", GOTO="brother_mfp_udev_1"
SUBSYSTEM!="usb_device", GOTO="brother_mfp_end"
LABEL="brother_mfp_udev_1"
SYSFS{idVendor}=="04f9", GOTO="brother_mfp_udev_2"
ATTRS{idVendor}=="04f9", GOTO="brother_mfp_udev_2"
GOTO="brother_mfp_end"
LABEL="brother_mfp_udev_2"
ATTRS{bInterfaceClass}!="0ff", GOTO="brother_mfp_end"
ATTRS{bInterfaceSubClass}!="0ff", GOTO="brother_mfp_end"
ATTRS{bInterfaceProtocol}!="0ff", GOTO="brother_mfp_end"
#MODE="0666"
#GROUP="scanner"
ENV{libsane_matched}="yes"
#SYMLINK+="scanner-%k"
LABEL="brother_mfp_end"

Any ideas, what to do?

I've got one of those, too.  After installing all of the Brother RPMs,
I had to run /opt/brother/scanner/brscan4/brsaneconfig4.  Even after
doing so, the scanner still refused to work, so I had to manually edit
/opt/brother/scanner/brscan4/brsanenetdevice4.cfg to set the scanner's
IP address.

I would comment out the SYSFS lines and see if that fixes anything.  I
would also remove the executable bit {chmod -x filename).

It seems they have put both SYSFS (used in RHEL5, so really old) and
ATTRS (new name RHEL6(say f12) and newer), but both point to the same
place, so as long as the bad one is not causing it to abort the entire
rule execution it should still work.

And read brothers documentation carefully, I think I found extra
instructions in one of their pages (I just remember the scanner being
tricky to setup for me).

Same here. IIRC I also edited that file by hand:

$ cat /opt/brother/scanner/brscan4/brsanenetdevice4.cfg
DEVICE=laser , "DCP-7055W" , 0x4f9:0x2ce , IP-ADDRESS=192.168.178.23

The fields are: local name, model, USBID (not relevant unless connected
by USB), IP address

I commented out the SYSFS line and the error message is gone. But the
scanner is still not working.

Forgot to mention in my first e-mail, the device is connected over USB
to the desktop.

I have not tried that sanning app, but I found that Xsane works well with my Brother DCP-L2550DW.
Package installed:  xsane-0.999-34.fc31.x86_64

We have a Brother DCP7065DN multifunction printer/scanner/kitchen-sink
here, difference is that it is on the household LAN, not USB connected.

However, everything works great even on my Centos system. Both Sane
and simple-scan work for scanning.

I don't know how the OP installed the Brother drivers, but there are
two ways: one is detailed with lots of tweaks you need to make, and
the other is relatively trivial.

You can either:
1. download the individual driver files and hack your system according
to the instructions on the site, or
2. download a single installer file that asks you questions then 
downloads and installs the driver files for you. After that you can
use whatever app you use on that system to set up a printer. On
Centos I usually use the print settings tool (though you should be
able to use CUPs on port 631 instead.)

For my printer (since I don't know what printer the OP has) I'd go
to this page

https://support.brother.com/g/b/downloadlist.aspx?c=us&lang=en&prod=...

which downloads the "driver install tool".

You could download the individual bits and pieces you need from that
page, too, but this one seems to do the whole job.

There's probably a page like that for your printer, too, and I'd
suggest you install it that way.

good luck!

Thanks for the input. I had originally tried to install with the
installer script, but for some reason it wanted to install .deb
packages on my Fedora system, so I abandoned it and installed the rpms
directly.

Now I went back to the script and hacked it a bit to always go with
rpms and then ran it. And now the scanner works :)
