My Brother all-in-one units (I've had two) have never done that.

I can get third-party toner cartridges for very reasonable prices.
Did you get that unit after crossing your fingers, and hoping that it works,
or did you verify compatibility somehow. I tried reconciling what's on the
market now versus xsane's hardware compatibility list without much luck.
I ended up ordering an HP all in one, MFP 232, because hplip's hardware
compatibility list claimed that model is fully supported, including scanning.
So it arrived. I used hplip to set it up, printing works fine. Pushing the
"scan" button in hplip guided me through downloading the driver, then it
launched xsane.
xsane sees the scanner. But the preview button hangs, then eventually comes
back with a "Faied to star scanner: error during device I/O".
Based on my Google searches:

It's not showing up in airscan-discover.
I have it connected via ethernet, I'm suspecting that scanning only works
via a direct connection. Digging further…
