How do the hardware MICR sorting rules work on the Canon CR-180?

The following section, found in the CR180options.ini file, pertains to the MICR sorting rules when the SortBy is set to 'scanner':
  1. ////////////////////////////////////////////////////////////////////////////////
  2. //  SortBy

  4. //                            The scanner will select it based on "micr rules" set below in
  5. //                            this file.  Upstream imaging will be available.

  16. // Pocket:

  18. //  1 (default) - the item will be sent to pocket 1 if the item MICR data

According to the sorting method chosen in the above settings, all items containing a substring, which starts after the first ':' and ends before the second ':', that is identical to one of the substrings specified by 'comparisonString' will be sent to pocket 1.

If the MICR read is "<123<4567=89" and if UseStartChar = true, UseEndChar = true, the StartChar ='<', and the EndChar ='=', then the extracted substring is "4567".  This is the string that will be used for comparisons based on the sorting rule specified and the contents of 'ComparisonString'.

If the sorting rule is 'Range', all items containing MICR lines with substrings in the range between string 1 and string 2 of 'ComparisonString' will be send to pocket 1.  If the sorting rule is either 'smaller' or 'larger' and there are several strings in the 'ComparisonString', the first string will be used for comparison.
