•Print quality pattern: displays the color blocks, representing each of the installed ink cartridges. Solid, even blocks of color indicate there are no print quality problems. When streaks are displayed or there are missing blocks, clean the print head using the procedure described in “Clean the print head” on page 64. If the color blocks still show print quality problems after cleaning the print head, align the product using the procedure described in “Align the print head” on page 64. If the color blocks continue to show print quality problems after cleaning and aligning, contact HP customer support.

•History log: contains information that might be used for diagnostic purposes if you need to call HP customer support.

If the product can print a self-test report and can print from the computer (if applicable), then there is no need to follow the remaining solutions, as the error message might be false.

Cause: The error was false.

If this did not solve the issue, try the next solution.
