Match a set of repeating
defects on a print job to
the marks on one of the
vertical lines. The line that
best matches the defects
on the print job indicates
which particular part is
causing the defect.
For example, the
distance between
these two marks
represents a
repeating defect
that occurs every
93.3 mm, which
means the print
cartridge is the
component that
needs replacing.
