b. Color bars: Look at the color bars in the middle of the page. You should see

seven color bars. These bars should have sharp edges, should be solid (not
streaked with white or other colors), and should be uniform in color throughout.

color across the entire page. The printer is operating correctly.

The top black bar is printed by the Black Ink Cartridge

The colored bars are printed by the Tri-color Ink Cartridge

Ragged or irregularly streaked or faded bars

Example of Bad Color Bars: The top bar is irregularly streaked or fading.

Example of Bad Color Bars: The top bar is ragged on one end.

To prevent problems causing ragged bars on the PQ Diagnostic Report, try the
following solutions:

Avoid leaving un-taped ink cartridges outside of the printer for an extended
period of time. For more information about handling ink cartridges, see


the ink cartridges


Always turn off the product using the

(Power) button, which prevents air

from getting into the cartridges. For more information about turning off the
product, see

Regular white streaks in the bars

Example of bad color bars: The blue bar has regular white streaks.

Bar colors are not uniform

c. Large-font text: Look at the large-font text above the color blocks. The type

should be sharp and clear.
