When did this used to work?
I'm assuming you have the Brother proprietary drivers installed, can you
check the versions of the 'brscan', 'brscan2', 'brscan3' and 'brscan4'
packages?
Can you get a log containing the calls leading up to the loop (the attached log
is from a fresh start where no scanning was started). You can get the log from
simple-scan with:
$ simple-scan --debug
if that is easier to capture it.
You can also get the equivalent from xsane by running:
$ ltrace -l libsane.so.1 xsane
The particular response from the driver is in fact valid, we are
correctly waiting for SANE_STATUS_EOF before stopping the sane_reads. So
this might be a buggy driver that's triggered by the options that
simple-scan sets.

Title:
simple-scan consumes 100% cpu and fills disk with logs attempting to
scan wirelessly with Brother MFC-7860DW
Status in Simple Scan:
Incomplete
Status in “simple-scan” package in Ubuntu:
Incomplete
Bug description:
Attempting to scan via wifi from a Brother MFC-7860 DW fails; the
scanner shows scanning but:
- no image appears in simple-scan.
- simple-scan consumes 100% CPU
- the ~/.cache/simple-scan/simple-scan.log grows indefinately until disk
space is exhausted.
This used to work perfectly and indeed the following provides an
instant work-around:
$ sudo apt-get install -y xsane && xsane
