The printhead cleaners keep the printheads in good condition and they prevent them from being damaged when the printer is not active. They service the printhead, making sure it is always ready to be used and prevent them from drying out when not in use.

Printhead cleaners come with the printheads when you purchase them. When you replace a printhead, always replace the printhead cleaner. Leaving the old printhead cleaner in the printer will shorten the new printhead's life and possibly damage the printer.
