Service Manual
There is a black and color purge pattern used to clear all printhead nozzles.
The nozzle test pattern prints all nozzles on a diagonal line. There should be
no breaks in the nozzle test pattern. A break in the pattern indicates one or
more nozzles are not working.
If a print quality problem exists, see
“Print quality service check” on
