Diagnostic Part 1: Printhead Reliability

The Nozzle Print Test test is designed to check if the Printhead nozzles print

correc

tly.

The nozzles check (top of the plot) is printed in a one-pass full swath mode.

The di

agnostics test prints out every single nozzle of each Printhead without

applying an error hiding or alignment algorithm.

For each Printhead, you can see both the adjacent and the consecutive

nozzl

es.

If any nozzles are not printing correctly they will be shown on the right of

each Printhead Nozzle test. There is a series of numbered stepped diagonal

lines. If one or more of the nozzles are clogged, malfunctioning or mis-

positioned, you will see that the stepped lines are broken or misdirected in

one or more places.
