Scanning rules for index sheet
The existence of the following recognition factors is judged using the image
pattern matching. (Image is binary.)
• The marks can be recognized if 50% or mo
re portion of each of them is
filled.
• For running out and excessive marking out, the two white/black search
patterns shown above are superimposed on the mark, and judgment is made
according to this matching ratio.
• The judgment criteria is as follows: Black matching: 80% or more White
matching: 50% or more.

Errors during scanning or printing of index sheets

scanned because it is dirty, set backwards, etc.
• Index sheet error 2 (Incorrect marking) is displayed if the image bubbles
cannot be read because they are not filled in correctly.
