Cleaning the Shuttle Frame Assembly
NOTE: To help steady the shuttle, be sure to obtain a shuttle stabilizer tool,
P/N 255447-001 (see Figure 37 on page 239).
1. Prepare the printer for maintenance (page 154).
2. Remove the ribbon cartridge and paper. (Refer to the User’s Manual .)
3. Unlock and slide the tractors outward as far as they will go on the tractor
support shaft. Leave the tractor doors open.
4. Remove the air shroud to expose the shuttle assembly.
5. Disconnect the shuttle logic, data, power, and MPU connectors.
6. Loosen and disengage the left and right shuttle retaining clamps.
7. Loosen the rear shuttle mounting screw and carefully lift the shuttle free of
the printer, and set it on the shuttle stabilizer tool (P/N 255447-001), on a
clean, level work surface.
NOTE: Since the paper ironer is now accessible, it can be cleaned with the
following three steps.
WARNING
Over time, the upper edge of the paper ironer can become sharp. To
avoid cutting yourself, handle the paper ironer on the sides.
8. Remove the paper ironer (page 221).
9. Wipe the paper ironer with a soft cloth to remove lint, ink, and paper
residue.
10. Install the paper ironer (page 221).
CAUTION
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.
WARNING
Do not rub the edges of the mask and cover as they can be sharp.
11. Remove the hammer bank / ribbon mask cover assembly (page 202).
IMPORTANT
Do not bend the ribbon mask when cleaning between the cover and
mask.
12. 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.
NOTE: Due to evaporation, do not open alcohol packets until they are
required for cleaning.
13. Use the brush provided to clear any debris from the outside of the ribbon
mask and cover plate. Use one or more of the alcohol pads to clean all
surfaces of the hammerbank cover assembly, removing ink residue and
debris.
14. Set the clean hammerbank cover assembly aside for later reassembly.
CAUTION
Do not use solvents or liquids to clean the hammer tips. Clean the
hammer tips gently; too much pressure can chip them.
