Cleaning the Print Head

Cleaning the Print Head
If your printouts are unexpectedly light or faint, or dots or lines are missing from the image, you may need to clean the print head. This unclogs the nozzles so they can deliver ink properly. Print head cleaning uses ink, so clean it only if quality declines.
You can clean the print head either from the printer’s control panel or using your printer software. To clean it using the printer software, the printer must be connected directly to your computer (not over a network); see Setting Up Network Printing for details. To clean the print head from the control panel, see your Printer Basics manual for details.
Caution: When you don’t turn on your printer for a long time, the print quality can decline, so turn it on at least once a month to maintain good print quality.
