Open the printer cover and inspect the ribbon cartridge and all
visible moving parts on the printer mechanism for signs of wear
or damage.
Use a low-pressure, dry air source, such as "canned air" available
at electronic supply houses and typewriter repair facilities, or a
vacuum, to remove accumulated paper dust from the printer
mechanism.
The printer ribbon contains a special lubricant to ensure that
the fine dot wires inside the print head receive adequate lubrica-
tion. Replace the ribbon frequently to prolong the life of the
print head. The printer requires no additional user-applied lu-
brication.
