6-2 LA Sensor Replacement (LA, LAIC Head)

After replacement of LAHD, reentry of MS parameters for the laser is required. (Refer to section 2 - 13

for reentry.) After replacement, wipe the LAHD laser window with alcohol.

– To replace, remove connectors (1), (2) & (3) and the 4 screws (4).

7. Head Up Spring Replacement

Remove head up spring (4) from spring stud (3) and replace. (Dia. 2 - 1 - 1~3)

8. Coupling θ Replacement

(1) Loosen the 2 screws (1), (2) in coupling θ and remove coupling.

(2) To mount, insert coupling all the way onto Z slider shaft and secure with screw (1). Tighten screw

(2) to fix spline shaft so that the dimensions given below are achieved.

9. Coupling Z Replacement

Since Z-axis motor must be removed to replace coupling Z, afterwards, Z-axis home positioning must be

adjusted and Z-axis height and laser related MS parameters must be reentered. (Refer to section 2 - 13

for reentry.)

(1) Remove motor as directed in section 2 - 3.

(2) Loosen screw (1) and remove coupling.

(3) To mount, place coupling all the way onto ball screw and tighten screw.

(4) Mount motor as directed in section 2 - 3.
