The printhead is the most critical component of your printer. It is used to deliver the ink to the page that you are printing. Don't touch the printhead with your fingers. Your printhead is a consumable that can deteriorate over time, much like the brakes on your car. It requires proper installation and ongoing maintenance to ensure the long service life of your printer. Most print quality problems are a direct result of improper care of the printhead. Proper installation and regular attention are the keys to maximizing the life of your printhead.
