Brother scanner problems


I have installed a Brother DCP-7040 printer/scanner and the print part works fine. I am having problems with the scanner part.

After running the Brother installer and adding the user to the lp group i do this:

sane-find-scanner
..
found USB scanner (vendor=0x04f9, product=0x01e9) at libusb:001:019
..

So it finds the scanner.But, I run
scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

And, of course simple scan, etc find no scanner.

ONe detects the scanner and the other does not. Why?

I know the sacnner works as I used it under Windows.

ubuntu 18.04

Some things to check....

1. Did you install the Brother scanner package yet?

2. Check that the relevant user is a member of the ‘lp’ group for r/w access to a USB-connected scanner.

3. Check that the Brother SANE backend (brother3) is present and uncommented in /etc/sane.d/dll.conf

Further to point 1 above, the requisite packages for the DCP-7040 are here....

Which Ubuntu version? Review the Brother scanner FAQ for any distro-specific steps that may be required. Make sue there is a udev rules file for the Brother scanner device in the /etc/udev/rules.d/ directory. For example, I have 55-brother-brscan4-libsane-type1.rules installed (as part of the scanner package install).

We can also examine the kernel messaging when the device is first attached. For that open a terminal window and do
Code:
dmesg -follow
then plug in the scanner and observe/capture the output. When posting such output, please enclose within code tags (refer to the '#' button in the advanced forum editor).

Another thought - sometimes USB 3.0 host controllers can cause issues with older scanner hardware, so if you have a mixture of USB 2.0 and USB 3.0 ports available, try using the former to see whether that makes a difference.

I upgraded my hard drive, so I did a completely fresh ubuntu 18.04 install and once againg tried to install scanner, and once again failure.
I have a vm of 16.04 that the scanner works perfectly under. I compared the udev files, etc to the 18.04 and everything is the same.

The only quirk I saw was that during the instgall on 18.04 I got this message:
Unpacking brscan-skey (0.2.4-1) ...
Setting up brscan-skey (0.2.4-1) ...
ls: cannot access '/etc/udev/rules.d/*.rules': No such file or directory

However, when I look the directory does exist with 60-brother-libsane-type1-inst.rules in it. I guess the install program created the directory.

I don't know what to try next.

Check the device permissions pertaining to your USB-connected scanner...
Code:
ls -l /dev/bus/usb/*/*
*If you need help determining that, run
Code:
sane-find-scanner
and that will report the bus and device number for the attached scanner.
