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.
The method of improving Nozzle Defects is to:
1Recover the Printheads, using the Front Panel Main Menu/Image Quality Maintenance/Clean Printheads option.
2Reprint the Printhead Nozzles Test Plot to verify that the defective nozzles have been corrected.
3If the problem continues, replace the defective Printhead.
