3-4-1. Replacing the HMS Head
1) Remove the cap bolts c (×2) to detach the HMS head. (The following Figure shows the HMS
head for the LF and RR heads.)
2) Reassemble the parts and components in the reverse order of disassembly. In the same
manner as described above, detach the HMS head from the LR and RF heads.

3-4-2. Replacing the Amplifier
1) Remove the cap bolts c (×2) to detach the head handle.
∗ When an optional bad mark reader is mounted, detach
the fiber unit from the bad mark amplifier.

3-4-3. Sticking the Label
After the label sticking surface has been degreased, stick the label. (The following Figure shows the
LF and RR heads.)
The LR and RF heads have the cable running direction opposite to that of the LF and RR heads.
Stick the label in an orientation so that it can be seen from the front.

3-4-4. Adjusting the HMS Height
Move the HMS sensor to a point above the calibration block. Loosen the SEMS cap bolts c at two
locations and adjust the distance between the bottom surface of the height sensor and the top
surface of the calibration block to a specified value of 40 ± 0.2 mm. At this time, check that both the
FAR and NEAR indicators are lit. After the distance has been adjusted to a specified level, secure
the height sensor with the SEMS cap bolts c at two locations.

After the sensor height has been adjusted, input the MS parameters related to the bad mark sensor
offset. For details about how to input MS parameters, see “MS Parameters”.
CAUTION
To prevent any personal injury, do not put your hand inside the
machine or your face or head close to the machine during operation
of the touch panel and/or HOD.

3-5. Replacing the Head Board
3-5-1. Replacing the Head Main Board
1) Remove the round screws c (×6) and clamps d (×2) to detach the main cover.
2) Disconnect various connectors and remove the SEMS cap bolts e (×6) to detach the head
main board.
3) Reassemble the parts and components in the reverse order of disassembly.
Since the head main board is delivered after it has been adjusted correctly, no adjustment work
is required.
∗ Follow the steps stated in“Head Vacuum Level and Temperature Sensor Output Level”on
page 1-4 for the QA table, only if any fault is found.
