This illustration shows the visible moving parts of the printer mechanism.
Use a low-pressure, dry air source, such as “canned air” available at elec-
tronic supply houses and typewriter repair facilities, or a vacuum, to re-
move 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 r eceive adequate lubrication. Replace the rib-
bon frequently to prolong the life of the print head. The printer requires
no additional user-applied lubrication. Ribbon cartridges, available in
black or purple, are sold separately. See “Inside Sales” in Chapter 1 for or-
dering information and part numbers.
