Scheduled Maintenance
Cleaning the Shuttle Frame Assembly
1. Remove the shuttle cover assembly (page 5–16).
2. Remove the shuttle frame assembly (page 5–42).
3. Remove the paper ironer (page 5–28).
WARNING
Over time, the upper edge of the paper ironer can become sharp. To
avoid cutting yourself, handle the paper ironer on the sides.
4. Moisten a clean, soft cloth with alcohol. Wipe the paper ironer to remove
lint, ink, and paper residue.
5. Install the paper ironer (page 5–28).
6. Remove the hammer bank cover assembly (page 5–15).
CAUTION
The thin plate (ribbon mask) of the hammer bank cover assembly is
fragile. Be careful not to over–bend or kink the ribbon mask when
handling and cleaning the hammer bank cover assembly.
7. Moisten a clean, soft cloth with alcohol. Wipe the hammer bank cover
assembly to remove lint, ink, and paper residue. Clean the holes in the
cover strips. Carefully open the cover assembly and wipe between the
hammer bank cover and the ribbon mask. (See Figure 2–2.)
CAUTION
Do not use any solvents or liquids to clean the hammer tips. Clean the
hammer tips gently—too much pressure can chip hammer tips.
8. Using a stiff, non–metallic brush (such as a toothbrush), gently brush the
hammer tips to remove lint and ink accumulations. Vacuum up any
residue.
CAUTION
The hammer bank contains a strong magnet. To prevent damage to the
hammer tips, do not let the hammer bank cover assembly snap into
place as the hammer bank magnet attracts it. Any impact of the cover
against the hammer bank can break hammer tips.
