How to improve print quality
Cleaning the print head
To ensure good print quality, the DCP will regularly clean the print
head, alternatively you can start the cleaning process when needed.
Clean the print head and ink cartridges if you get a horizontal line in
the text or graphics on your printed pages. You can clean two colours
at a time (BLACK/CYAN/YELLOW/MAGENTA), or all four colours at
once.
Cleaning the print head consumes ink. Cleaning too often uses ink
unnecessarily.
WARNING
Do NOT clean the print head by touching it with your hand or a
cloth.
