Cleaning the print head
To maintain good print quality, the machine will automatically clean the print head when needed. You can start the cleaning process manually if there is a print quality problem.
Clean the print head if you get a vertical line in the text or graphics, or blank text on your printed pages. Cleaning the print head consumes ink. Cleaning too often uses ink unnecessarily.
