6. Set the pickup height jig to zero, and remove the stopper bracket. Then
slot the jig onto the device table (slot no. 23) and install the nozzle jig on
the nozzle holder (no. 1).
7. Rotate the cam axis to 170°, ensuring that the needle of the pickup height
jig is directly below the nozzle jig.
8. Manually move the NZ-axis until the dial gauge reads zero (at this point
there should be a space of 0.65 mm between the tip of the nozzle and the
feeder). Take note of the motor pulse count at this point.
9. Repeat the procedure for all 16 heads. Take the average value of the 16
heads and set this as the NZ origin position in the machine’s calibration
data using the following commands:
[MAINTENANCE] → [CALIBRATION] → [PICKUP REFERENCE] →
[NZ ORIGIN POSITION].
