Cleaning the Printhead
In order for the printhead to provide good print quality, it must
maintain close contact with the media. Therefore, cleaning media
debris from the printhead is very important. Clean the printhead
after every roll (1,800 inches or 46 m) of media or when
necessary.
Caution
Do not use sharp objects such as knives or
screwdrivers to scrape the printhead clean.
Cleaning with sharp objects will damage the
printhead. Clean with only a cotton swab, or a
clean, lint-free cloth or tissue damp with
isopropyl alcohol.
Conseil
N’utilisez pas d’objets pointus tels que couteaux
ou tournevis pour nettoyer la tête d’imprimante.
Nettoyer avec des objets pointus endommagera
la tête d’imprimante. Nettoyez-la seulement
avec de la ouate ou avec un linge propre et libre
de peluches, humecté avec de l’alcool
d’isopropyl.
To clean the printhead
1. Turn the printer power off and remove the power cord.

lever (on the left side of the printer) toward the front of the
printer. Lift the printhead up into the full open position.

adhesive, or debris from the print surface on the bottom of
the printhead.
