I finally updated the bios to this last version.
According to the release notes Epson has improved the AID functionality (again!)
However, I still don't feel confident enough to enable the Auto nozzle check.
Maybe it has to with the word "improved", we don't need improvements, we need something that just works!
When I test this "improvement", I'll give you some feedback, unless someone else tries it first.
