Cleaning The Shuttle Frame Assembly
1. Remove the shuttle cover assembly (page 203).
2. Remove the shuttle frame assembly (page 242).
3. Remove the paper ironer (page 230).
4. Wipe the paper ironer with a soft cloth to remove lint, ink, and paper
residue.
5. Install the paper ironer (page 230).
6. Remove the hammer bank / ribbon mask cover assembly (page 200).
ATTENTION
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. Using a clean soft cloth, wipe the hammer bank cover and ribbon mask to
remove lint, ink, and paper residue. Clean the holes in the cover strips.
Carefully wipe between the hammer bank cover and the ribbon mask
(early models).
ATTENTION
Do not use 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. (See Figure 6.)
Vacuum up any residue.
<2> Over time the upper edge of the paper ironer can become
sharp. To avoid cutting yourself handle the paper ironer on
the sides.
