I will have a look at this when I get some time. I have seen this once
on my own scanner, but thought that the latest git version fixed it.
This could be a timing issue that shows up on wlan only (I use a wired
network connection).  Just to be sure: did you power off/on the scanner?
It looks as if the protocol stack in Canon devices get confused
sometines.....
