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 sceptical that it will help.

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 SCSI scanners found. If you expected something different, make sure that # you have loaded a kernel SCSI driver for your SCSI adapter.

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.

What else can I try?
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?
Fred
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'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?

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.

My #1 rule is always "check the dumb stuff first", but I constantly find that I can't always convince my brain to descend to the level of dumbness required :).

Especially when the dumbness is hiding in plain sight.
