Interpreting the Test Page
The first line of the test page is the code level and the code level date.
The next line is the black print cartridge nozzle pattern.
The next three lines are the purge pattern.
All nozzles print the purge pattern.
The purge pattern action cleans (purges) the nozzles.
Another nozzle test pattern follows the purge pattern.
The patterns repeat for the color cartridge.
The next patterns to print are the vertical and horizontal alignment test patterns.
These patterns are used to align the black printhead to the color printhead.
The alignment must be performed whenever a print cartridge is replaced.
Refer to Section 3.3 of this Service Handbook for information on the printhead alignment
