Interpreting the Print Diagnostic Print
Quality prints
The print produces five pages, one page of
each primary color and one page with
4 primary color fills.
Look for:
1.
Consistent fills in each primary color.
Each color should be consistent across
the width of the page with no voids.
2.
No separation or misconvergence where
each bar meets its neighbor. Each bar is
separated by a thin black line.
3.
Look for thin white lines that would
indicate a dirty LED lens or a scratched
imaging drum
4.
Look for dark lines that would indicated a
dirty or damaged imaging drum.
5.
Look for complete fusing. Cold or hot
offset fusing could indicate the incorrect
paper weight has been selected
Interpreting Test Pattern A
This pattern consists of color blocks and
bars. Use this pattern to identify defects
such as deletions, banding, color
misregistration, side-to-side density
problems, and text problems.
Look for:
1.
Solid fills in the color blocks.
2.
Ensure the small text is legible and not
broken.
