3-3. Replacing the Bad Mark Sensor
3-3-1. Sensor Assembly
1) Remove the SEMS cap bolts c (×2) to detach the BMR lens bracket A (B). (The following
Figure shows the BM lens bracket A (for RR head).)
2) Remove the nut d and washer e to detach the lens f.
3) Reassemble the parts and components in the reverse order of disassembly.
In the same manner as described above, remove the BMR lens bracket B (for LR head).
∗ Nuts d (2 pcs.) and washer e are accessory parts supplied with the fiber unit.

Move the bad mark sensor to a point above the calibration
block. Loosen the SEMS cap bolts at two places and move
the BMR lens bracket so that the distance between the
surface of the bad mark sensor and the top surface of the
calibration block becomes 28

mm.
After the sensor height has been adjusted, secure the bad
mark sensor with SEMS cap bolts.
After the bad mark sensor has been mounted properly,
input the bad mark sensor offset of the MS parameters.
(For details about how to input MS parameters, see “MS
Parameters”.)

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.
3-3-3. Amplifier
1) Detach the amplifier while keeping the amplifier pushed downward. (The following Figure
shows the RR head.)
2) Reassemble the parts and components in the reverse order of disassembly. In the same
manner as described above, detach the amplifier from the LR head.

3-3-4. Assembling the Fiber Unit to the Amplifier
1) Open the case cover and flip down the one-touch lock lever.
2) Make the projection faced toward the side where there is no LED and insert the fiber into the
amplifier approx. 13 mm.
After the fiber has been inserted, flip up the lock lever and check that the fiber is not
disconnected. After that, close the case cover.
