Turn the printer off.
Unplug the power cord from the wall outlet.
 | CAUTION—HOT SURFACE: The printhead may be hot. If so, allow it to cool before touching. |
Squeeze the left and right latches on the ribbon cartridge, and then lift it out of the printer.
Every few months, use a soft brush and a vacuum to remove dust, ribbon lint, and pieces of paper from the printer. Vacuum any dust from around the printhead and from inside the printer.
Clean the outside of the printer with a damp cloth and mild soap. Do not use spray or chemical cleaners anywhere on your printer. Do not use liquids or spray near the air vents. For stubborn ink stains on the outside of the printer, use a commercial mechanic's hand cleaner.
