Hi Nicolas,
That is quite strange. This is one of the patches which I believe I
submitted during testing of various scanners, including the MP760/780.
The MP460 and MP510 required a new addition (condition) which only
have applied to them (for now) and no other devices, so I do not
understand exactly how this affects unrelated devices. Unfortunately I
now no longer have any of these machines, but I will compare the code
I still have.
