Replace the Printhead

You need to replace the printhead periodically when it wears out due to the rapid

the printhead depends on factors such as what type of images you print, the type
of media or ribbon you use, the amount of energy to the printhead, the print speed,
and the ambient temperature of the room you print in. The firmware detects the
