After replacing head, center nozzle & head. Part of the MS parameters will have to be reentered.
(Refer to section 2 - 13.)
– Centering nozzle (X direction)
When assembling, the LAIC head is used as basis for vertical alignment with the base surface.
The LA is centered with reference to the LAIC head. Thus, when the LAIC head is replaced, the
LA head serves as reference for centering.
For method of adjustment, refer to the QA Table under Head, Head centering (X direction).
– Centering nozzle (Y direction)
In the Y direction, the distance is determined by shims between head & head plate.
For method of adjustment, refer to the QA Table under Head, Head centering (Y direction).

1-3 LAIC head
(1) Disconnect the wire bundle for Z & φaxes, Z-axis deceleration sensor and IC head encoder from
the head PCB and remove the LA wire bundle from the connector. Disconnect air tubing from
couplings.
(2) While holding head with hand so that it does not drop, remove the 4 SEMS cap screws (1).
Remove head from head plate by sliding it off positioning pins.
(Dia. 2 - 1 -3)
Note: There should be two shims (above & below) between the head and head plate. These shims are
used for centering the head plate and nozzle in the Y direction. When remounting head reuse
shims. When mounting a different head, use the shims provided with it.
Stick shims to head plate with grease before mounting head.
Shim types Thickness
Head center shim A (3019721000) t0.1
Head center shim A (3020721000) t0.05
Head center shim A (3021721000) t0.03
(3) Reassemble by reversing the procedures.
