•If the pattern looks good as shown below, the print head is clean.
•If any dots or segments are missing or deflected as shown below, run a cleaning cycle by pressing and holding the Menu button for at least 3 seconds. Then print another nozzle check pattern to make sure the nozzles are clean.
Running a Power Cleaning Cycle
You can run a power cleaning cycle from the control panel if the normal cleaning process is not sufficient to clear the nozzles. However, the power cycle uses a large quantity of ink, so it is recommended only as a last resort.
The cartridges need to be at least 50% full to use power cleaning. You may need to replace a low cartridge to run the cleaning cycle. After cleaning, you can reinsert the old cartridge.
