Head unit on bench:
Height of Z-slider shaft: 40 ±0.02 mm (eccentric center as measured at the Z pickup position)
Pickup
height
Mount the jig nozzle (φ20) on the Z-slider shaft, apply a dial indicator to the periphery of the jig nozzle, and
turn the Z-slider shaft. Check that eccentricity is 0.02 mm or less and, at the same time, select head center
shim A, B, or C and place it between the head bracket and head plate jig so that the eccentric center
becomes 40 ±0.02 mm. At this time, measure Z position at the pickup point [see the assembly drawing of
head assembly (750, 760, 7520, 7620)]. At the same time, measure also the traveling parallel alignment in
Z-direction.

QA Table
Error in each head in Y-direction with reference to R head: ±0.02 mm (eccentric center as measured at the Z
pickup position)
Mount heads on the head plate and fit the jig nozzle (φ20) to the head that serves as the reference (normally R
head; the head mounted if heads are replaced). With the center of runout in the Y-direction at 0, move the head
in the X-direction. Remove the jig nozzle and, instead, mount it to the head to be measured. Select head
center shim A, B, or C and place it between the head plate and head bracket so that the error in runout center in
Y-direction becomes ±0.02 mm. Measure, at this time, the Z position at the pickup point [see the assembly
drawing of head assembly (750, 760, 7520, 7620)].
