Removal
1. Prepare the printer for maintenance (page 152).
2. Remove the shuttle cover assembly (page 203).
3. Disconnect the MPU cable connector (page 272, Figure 49).
ATTENTION
To prevent electrostatic damage to electronic components, wear a
properly grounded static wrist strap when handling circuit boards, the
shuttle frame assembly, and any other electronic component.
4. Disconnect the shuttle motor cable connector (page 272, Figure 49).
5. Disconnect the hammer drive and hammer logic cables connectors from
the terminator board on the shuttle frame assembly.
6. Loosen the side 5/32 inch socket head clamp screws and pull the clamps
back and off the guide shaft. Do not remove the clamps.
7. Loosen the center 5/32 inch socket head screw enough to release the
shuttle frame assembly from the base casting.
8. Unlock and slide the tractors outward as far as they will go on the tractor
support shaft.
9. Grasping the support legs cast on both sides of the shuttle motor, lift the
shuttle frame assembly out of the base casting.
Lift it slowly and
carefully: the shuttle frame assembly is heavy.
