The Nozzle Print Test test is designed to check that the Printhead nozzles print correctly. Troubleshooting The nozzles check (top of the plot) is printed in a one-pass full swath mode. The diagnostics 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 nozzles. 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. Below, the stepped lines highlighted in yellow are broken. When the line is completely broken, this means the nozzle is out. Below, the stepped lines highlighted in yellow are misdirected. When the line is misdirected, this means the nozzle is malfunctioning or out of position. On the left of each Printhead Nozzle test, there is a series of horizontal straight lines. If one or more nozzles are misdirected there will be unequal spaces between the corresponding lines.
Corrective action If the printer has nozzle defects, you can still get perfect print quality results. The printer can automatically compensate for nozzle defects, so there is no need to replace the Printhead. ENWW Print-quality troubleshooting 9
