I have a Brother DCP-7055W all-in-one laser printer and scanner, connected by Wifi to my LAN. The printer works perfectly, and the scanner worked at least up until a couple of weeks ago when I last used it. Now, it seems to have disappeared. Both simple-scan and scanimage report no scanners found.
I've reinstalled the RPM package downloaded from brother.com. I've
so, you reinstalled the RPM. did you do that manually, or via the (I can't think what they call it) tool that asks you for the model of your device then retrieves the bits and pieces and installs them, also presumably doing the other tweaks necessary?
the manual installation usually involves more than installing the RPM,... on their download page(s) for your particular Linux driver, there is usually a link to a list of additional steps that have to be done by hand to finish installation. Did you go thru those, or at least verify that they are still in place?
I did exactly what I've done several times in the past: download the RPM and run 'dnf install ...". This has always worked.
However on closer inspection I see this from the configure tool:
# brsaneconfig4 -a name=Brother model=DCP-7055W ip=192.168.1.4 # brsaneconfig4 -d [...] sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the # result is different from what you expected, first make sure your # scanner is powered up and properly connected to your computer.

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). ----------------------------- ----------------------------- /etc/opt/brother/scanner/brscan4//brsanenetdevice4.cfg: ----------------------------- /etc/opt/brother/scanner/brscan4//Brsane4.ini: ----------------------------- /etc/opt/brother/scanner/brscan4//models4/ext_9.ini: ----------------------------- /etc/opt/brother/scanner/brscan4//models4/ext_1.ini: [...]
Note that it's searching in /proc/bus rather than /sys/bus, which may be wrong. However AFAIK this hasn't changed since I've been using it and in any case shouldn't matter as it's not connected via USB.
