Clean the printhead
If your print is streaked or has incorrect or missing colors, the printhead may need to be cleaned.
There are three stages of cleaning. Each stage lasts about two minutes, uses one sheet of paper, and uses an
increasing amount of ink. After each stage, review the quality of the printed page. You should initiate the next
phase of cleaning only if the print quality is poor.
If print quality still seems poor after you complete all stages of cleaning, try aligning the printhead.
NOTE: Cleaning uses ink, so clean the printhead only when necessary.
NOTE: Failing to turn o the printer correctly can cause print-quality problems.
