Control Panel (Internal) Test Print
A test print is available to aid in determining the quality of output from the printer and to assist
in troubleshooting image-quality problems. Each area of the test print is used for a image-
quality parameter. The following pages explain each of the areas and the image-quality
parameters. Follow these guidelines when generating the test print:
■ Use supported paper from a fresh, unopened ream
■ Print five copies of the test print.
■ Discard the first two prints and retain the remaining prints for image-quality analysis.
Deletions
Inspect the test print for the presence of deletions or unprinted spots. If these are found, see
Spot or Vertical Deletions on page 3-10.
Fusing
Rub the image three times at the indicated points with a soft cloth or tissue. The toner should
not lift off of the surface of the print. If the image smears or toner lifts off the image onto the
cloth, see Unfused Image on page 3-11.
