CAUTION! If the Z shaft encoder is replaced, DO NOT OPERATE THE
EMBROIDERY PERIPHERAL until the new Z shaft encoder is properly
calibrated!
To replace the encoder follow these steps:
1. Turn the machine OFF, then disconnect the power from the power source.
2. Remove the rear cover.
3. Disconnect the Z encoder harness from the z encoder.
4. Using proper antistatic precautions, disconnect the encoder cable from the CPU
board.
5. Loosen the two coupler socket head cap screws that secure the coupling to the Z
encoder shaft (see Figure 3-8).
6. Loosen and unthread the jam nut on the encoder shaft.
7. Pull the encoder out of the shaft coupling and encoder mount. Capture the jam
nut and washer as the encoder shaft is removed.
8. Insert the new encoder/shaft into the hole of the encoder mount, place the
washer and then the jam nut onto the encoder shaft as you insert the shaft
through the mounting plate.
