After updating Ranger my MICR sorting no longer work. The MICR sorting rules also worked for the CR-180(II).
The Polarity implementation was corrected in the new Canon drivers. This may affect applications currently using MICR sorting rules. If MICR sorting no longer works as expected then you may consider changing the Polarity option to false.
CR190Options.ini:
[MicrSortRule1]
Polarity=false
