10. Orient the connector on the encoder cable so the outside black wire is to the

right and will plug into pin 1 of the new encoder (see inset in Figure 3-3). Push

the encoder cable connector onto the new encoder.

CAUTION! If the Z shaft encoder is replaced, DO NOT OPERATE THE

EMBROIDERY PERIPHERAL until the new Z shaft encoder is properly

calibrated!

11. Calibrate the Z encoder per the following procedure.

Calibration

CAUTION! Failure to properly calibrate the Z shaft encoder after

replacing it, may cause damage when attempting to operate the

machine.

Note: This procedure requires the use of a special service tool: the Melco 10 needle

head up fixture (p/n 995673-01).

1. Install the Z shaft encoder as described previously.

Note: To perform this procedure, it is important that the peripheral does

not "download." To insure this condition remove the network cable (or

boot disk if being used).
