6.14 Linear Velocity Transducer (LVT) Coil and
Magnet
Use the following procedure to remove and replace the LVT coil and
magnet (Figure 6–14).
6.14.1 Removing the LVT Coil and Magnet
1. Remove the top enclosure (see Section 6.7).
2. Remove all print actuator modules (see Section 6.8).
3. Remove the shroud and ribbon drive assembly (see Section 6.10).
4. Disconnect the LVT at connector CA17-P7, located between the drive
mechanism and the left side panel.
5. Use an 8 mm wrench to loosen the sensor support captive bolt.
6. Use an 16 mm open-end wrench to loosen the hex side of the LVT
magnet assembly.
7. Remove the LVT coil and magnet from the printer.
6.14.2 Replacing the LVT Coil and Magnet
1. Use an 8 mm wrench to tighten the captive bolt that was loosened in
step 5 of the previous section. Secure the bolt so that some resistance
is provided to the movement of the LVT coil assembly.
2. Use a wrench to tighten the hex end of the magnet.
3. Using a nylon gauge P/N 29.26861, adjust the position of the LVT
coil assembly over the magnet until the coil extends 7.84 + 0.25 mm
beyond the end of the LVT magnet support tube.
4. Tighten the support bracket until the LVT coil is secure.
5. Ensure that there is visible clearance on all sides between the magnet
and the opening in the coil assembly. If there is a lack of clearance
on any side, correct by using shims P/N 29.26862, to realign the coil
assembly.
