Cleaning the Printer Case

Clean the case with a lint-free cloth and isopropyl alcohol as necessary to
remove dust from cooling vents. If the vents become obstructed, the printer
may overheat, which can result in pauses while printing labels and damage to
the electronic circuitry inside the printer.

Cleaning the Printhead

Cleaning media debris from the printhead maintains close contact between the
media and printhead, which provides good print quality. The printhead should
be cleaned after every five rolls of media. Always clean the printhead
immediately if a label jams in the printer.
To clean the printhead, follow the steps under "Opening the Printer." Then use
a cotton swab or a clean, lint-free cloth and isopropyl alcohol to clean the
printhead. Be persistent. It may take a long time to remove label adhesive.
