Use the POSITION CHECK function to check whether the transmitter and
receiver (scanning head) are aligned in terms of the optical axis.
The procedure is as follows:
1. Use PRM to display "HEAD1" and "POSITION CHECK" on the
subdisplay.
2. Attach the optical axis checker to the receiver.
3. When the transmitter and receiver are aligned in terms of the optical axis,
"GOOD" will appear. If not, "P-Err" will appear.
4. When 2 scanning heads are used, press PRM again to display "HEAD2"
and "POSITION CHECK". (To use 2 scanning heads, the optional PC
board for the second scanning head is required.) Then, use the optical
axis checker to check whether the transmitter and receiver of the second
scanning head are aligned in the same manner as those of the first
scanning head.

Not applicable to LS-3033 SO (8073).

When you use the LS-3033SO (8073), note the following:
1. Optical axis alignment — Install the transmitter and receiver so that the
both reference base edge are aligned. This also completes the optical
alignment. The optical axis checker, which is provided for standard LS-
3033, cannot be used for LS-3033SO (8073). No optical axis checker is
provided for LS-3033SO (8073) for this reason.
2. Transmitter-to-receiver distance — Set this distance to 120 mm.
