Print-Quality Troubleshooting
Contamination Check
This check produces five pages that are useful for analyzing repeating defects
such as lines or spots that occur at regular interval. By measuring the size of
the interval it is possible to determine which printer component is causing the
problem.
Pages 1 through 4: Vertical and horizontal scale patterns on a 20% density
background of one color; for evaluating regularity and intervals.
Page 5: A Pitch Chart that lists repeating defect intervals and their associated
components.
