Cleaning The Shuttle Frame Assembly 1. Remove the shuttle cover assembly (page 326). 2. Remove the shuttle frame assembly (page 362). 3. Remove the paper ironer (page 349). Over time the upper edge of the paper ironer can become sharp. To avoid cutting yourself, always handle the paper ironer on the sides. CAUTION ATTENTION 4. Wipe the paper ironer with a soft cloth to remove lint, ink, and paper residue. 5. Install the paper ironer (page 349). 6. Remove the hammer bank / ribbon mask cover assembly (page 325). The thin plate (ribbon mask) of the hammer bank cover assembly is fragile. Do not over-bend or kink the ribbon mask when handling and cleaning the hammer bank cover assembly. ATTENTION 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). Do not use solvents or liquids to clean the hammer tips. Clean the hammer tips gently; too much pressure can chip them. 8. Using a stiff, non-metallic brush (such as a toothbrush), gently brush the hammer tips to remove lint and ink accumulations. (See Figure 54.) Vacuum up any residue. 434
