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 your on-screen Reference Guide 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. Follow these steps to clean the print head from the printer's control panel: 1. Make sure the printer is turned on but not printing, and the red b error light is off. If the red b error light is flashing or on, you may need to replace an ink cartridge; see page 51 for details. 2. Press to highlight More Options, then press OK. 3.

software. To clean it using the printer software, the printer must be connected directly to your
computer (not over a network); see your on-screen
Reference Guide

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.
