Replace the Printhead
You need to replace the printhead periodically when it wears out due
to the rapid heating and cooling process used during printing. How
often you need to replace 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 new
printhead when you restart the printer.
1 Turn the printer off and disconnect the printer from power.
2 Open the media cover.
3 Remove the media and ribbon (if installed).
4 Turn the printhead lift lever counterclockwise to raise the
printhead.
5 Detach the magnetic pressure arm from the printhead bracket and
disconnect the two cables from the printhead as you remove it from
the printer.
