Match a set of repeating defects
in your print to the corresponding
marks on the appropriate vertical
line. This line indicates the item,
such as the transfer roller,
causing the defect.
For example, the distance
between these two marks
represents a defect repeating
every 44 mm; this is caused
by an imaging unit. When
correcting a repeating defect
by replacing a routine
maintenance item, follow
the instructions included with
the routine maintenance item.
Note: The repeating defect
must be measured accurately
to ensure the correct item is
replaced.
