Switch off the printer power and remove the power cord before
cleaning any part of the printer.
Avertissement: Mettez l'imprimante hors tension et débranchez le
câble d'alimentation avant de nettoyer une parte de l'imprimante.
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 of media (152 m or
6,000 in) or ribbon (457 m or 18,000 in). Clean more often if necessary.
There are two ways to clean the printhead:
• Use the cleaning card.
• Use a cotton swab and isopropyl alcohol.
Do not use sharp objects such as knives or screwdrivers to scrape the
printhead clean. Cleaning with sharp objects will damage the
printhead.
Attention: 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.
To clean the printhead using the cleaning card
1 Turn off the printer and remove the power cord.
2 Remove the media cover.
3 Disengage the printhead by rotating the head lift lever clockwise until
the printhead releases. This raises the printhead so that you can clean it.
4 Remove the media and ribbon.
5 Open the pouch and remove the cleaning card.
