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
rebooted Fedora (you never know). I've also checked that the scanner
itself is working (from a Windows laptop).
What else can I try?

Try it with Vuescan (www.hamrick.com). It's proprietary but can be run free in demo
mode then you
may see if it at all works in fedora.

Vuescan doesn't see the scanner either.

Probably not helpful, but I gave up on linux and scanners
a long time ago. I run my Windows virtual machine to access
my network scanner now and save the scanned images to
a share that lives native back on the linux host :-(.

My Windows VM can't see it either, though that may be a configuration
issue with network bridging.

I have run
XSane Scanning on PCLinuxOS for ages on several computers
with KDE4 and KDE5 on an Epson WP-4530 with no problems at all.
The Epson all-in-one is connected via cat-5 cable to the LAN, which is
hardwired to two desktops and a laptop. There have been several routers
during that time.

When I grep the /var/log/dnf.rpm.log-2017* files, I find that there was
an update of all the sane packages on March 25, 2017, and the kde sane
packages on March 26, 2017. I suspect that that somehow introduced a
regression for you. You could try downgrading from Koji packages, or
looking for rpmnew configuration files.
For some reason, bugzilla.redhat.com isn't available right now, so I
couldn't check for open problem tickets. But, that would be your next
step, opening a ticket if there isn't already one opened.

Well BZ seems to be broken at the moment. I rolled back to version
1.0.25-4 (October 2016) and it made no difference, even after
reinstalling the Brother package and power cycling the printer. Note
that it still prints wirelessly.
Could it be a firewall issue? Seems unlikely as the print function
works, but I'm clutching at straws here. Not sure what ports to check.

There is, of course, always the possibility that the
scanner just broke. I know I've always noticed a tendency
for hardware to wait till a software update has just been
applied to break (so it can force you to waste more
time figuring out the problem - I'm sure it does it
deliberately :-).
Does it have controls that let you manually scan from
the machine itself? If so, do they work?

You just have to have the right touch; it's all in the keyboard
presses. :-)
Description of problem:
HewlettPackard 5300C USB scanner works on Ubuntu 14.04LTS, fails on
Fedora 25. xsane-find-scanner and scanimage -L find it. When I run
xsane, it finds it (at the correct USB address with correct driver,
avision). Click Scan button, the scanner makes a starting up noise,
goes silent, about 2 minutes later xsane reports an I/O error. After
that, scanner is not found without power down/up.
I'm stumped. Try booting from earlier kernel?

I can see the page but unfortunately that report mentions an option for
a specific model different from mine and I can't add anything. When I
try to log into BZ it throws an internal error (under both Chrome and
Firefox).
My package (which has worked reliably up till now and was last updated
in November, doesn't even install a config file in /etc/scan.d. It's
all under /opt and there are no text config files.

The earliest one I have is 4.10.8-200. It didn't make any difference
and I'm not keen on hunting for old kernels to see if they work as I'm

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:

check that the scanner is plugged in, turned on and detected by the

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.

FWIW, I have Centos-7, which is kept up to day, and a brother
dcp-7065DN, which is on the LAN, via cat5 not wireless.
when I start up Xsane, it scans for devices then reports the brother
DCP-7065DN as found. Though, gotta admit, I haven't used it to do an
actual scan in some time, so who knows if it actually works.
which makes me wonder if it is actually connected via wireless,
or only should be...: can you ping the device?

I have an HP color laser writer/scanner that I connect to via wireless.
I find that it becomes unusable if I don't use it after awhile. I
went over to the room where the scanner is and noticed that it worked
great until the power saving feature turned on. My problem is that my
linux box can talk fine to the printer, but cannot wake it up once it's
gone into that powersaver mode.
If I power cycle the printer or do something else to wake it up, then
it can talk to my linux box until it is quiet for a few minutes.
When I boot in Windows, this isn't a problem. I've decided that the
linux driver is great for giving printing commands, but not so great
for all this power management stuff.

I print once per day (the Guardian crossword :-) and rarely scan, so my
printer is almost always asleep. I've also had it for three years
without this problem so I don't think that's it.

That sounds like a good idea; I'd definitely try power cycling the
printer/scanner.

I had a similar problem a couple of weeks ago. I only scan
perhaps once a year, but my trusty old Canoscan N650U is
always up to the job and scanning has been painless i Fedora
for me.
Well, recently, no matter what I did, reboot, reload the
module, etc, nothing worked, not even importing into Gimp,
running xsane, nothing.
Then, I tried skanlite and it worked like a charm! I think you
also need kf5-libksane and sane-backends-drivers-scanners,
but, if so, they should be pulled in as dependencies.

Nope, skanlite can't find the scanner either.

Older kernel? Though I thought everything to do with scanners came from
the sane package (so check RPMs log for changes), perhaps it's an
interface problem? (USB?)
Reboot the scanner, unplug the power and hard reset?
Can the scanner self scan and print?

After a huge amount of to-ing and fro-ing, the details of which are too
boring to relate, it turned out to be something devastatingly simple
(isn't it always?). The scanner had somehow become assigned to the
wrong IP address in my router's static DHCP table. What threw me was
that it still worked as a printer *despite having the wrong IP number*.
I can only assume that CUPS was finding it with some kind of broadcast
or UPNP search, but that SANE needs more precise information.
Wouldn't it be great if CUPS and SANE worked better together, or even
merged?
Apologies for wasting everyone's time, but it works now.

Especially when the dumbness is hiding in plain sight.
