Top Housing Replacement
To replace the Top Housing proceed as follows:
1. Check that all boards and components are firmly secured. Check for loose
screws. Ensure that no screws or foreign bodies are loose in the bottom of the
case.
2. Inspect all the internal cable assemblies and ensure that they are in good
condition and that no visible damage can be seen. Ensure that no cable
assemblies are strained, crushed or caught.
3. Ensure that all connectors are firmly home.
4. Position the Top Housing in front of the Base Assembly and, without straining the
ribbon cable, plug in the interconnecting cable from the keyboard to the main
board MK 11-10. See picture next page.
Note: It may be necessary to tilt the Top Housing for the cable assemblies to
reach.
5. Turn the Top Housing slightly counter-clockwise and lift it over the paper tray lid.
6. Carefully position the Top Housing on the Base Assembly and close the paper tray
lid.
7. Grasping the Top Housing and the Base Assembly to ensure that they cannot part,
carefully turn the unit upside-down and replace the six securing screws and
washers in the extreme corners and edges of the unit. Return the unit to the
upright position.
8. Carry out the functional check procedure detailed in Chapter 3.
