3.4.5.3 Uniformly Spaced Print Troubles (bands, smudges, etc.)
When horizontal stripes and spots appear at fixed intervals, it is highly possible that a
specific roll has caused the trouble. If this happens, you might be able to easily solve
the problem by measuring the interval between the stripes or spots on a test print, and
checking the relationship between the pitches shown in the table below (note that the
pitch does not necessarily match the perimeter of the roller).
