Wait until the printhead is coolCleaning the inside: Every three
months, use a soft brush and a vacuum to remove dust, ribbon lint, sawdust,
and pieces of paper. Remove the ribbon cartridge to prevent the ribbon
from going into the vacuum. Vacuum any dust from around the printhead
and in the printer cavity.
Cleaning the cover: Clean the outside of the printer with a damp
cloth and mild soap. DO NOT use any spray-type or chemical cleaners
anywhere on your printer. Do not put any liquids or spray near the air
vents. For stubborn ink stains on the cover, use a commercial mechanic's
hand cleaner.
