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 after every roll (or 6,000 inches) 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 On/Off switch to the off position and remove the power cord.
2. Remove the media cover.
3. Rotate the head lift lever clockwise until the printhead releases. Rotating the
head lift lever raises the printhead to allow for cleaning.
4. Remove the media and ribbon (if necessary).
5. Use a cotton swab moistened with alcohol to remove any dirt, adhesive, or
debris from the print surface on the bottom of the printhead.
6. Wait 5 to 10 seconds for the print surface to dry. Replace the media and
ribbon.
7. Engage the printhead by rotating the head lift lever counterclockwise until
it locks in place.
8. If you are finished cleaning, replace the media cover.
