10. IMAGE POSITIONING SECTION
10.1 ADJUSTING THE IMAGE POSITION
Purpose: To ensure that the image is well centered when the Image Position
key is set to "0".
Adjustment Standard: The gauge [A] must be inserted.
1. Remove the rear cover.
2. Turn on the main switch. This way, the image position is returned exactly
its initial position. (The image position indicator shows "0".)
3. Make sure that it is possible to insert the gauge [A] (P/N C2009002).
4. If the gauge [A] cannot be inserted into the hole of the gear [B], move the
gear [B] to enable the gauge to be inserted into the hole as follows:
a) Disconnect the image positioning motor connector [C].
b) Loosen the Allen screw [D] so that the gear at the end of the image
position sensor shaft [E] rotates freely.
c) Turn the gear [B]. To do this, turn the worm gear [F] manually until the
gauge [A] can be inserted into the hole of the gear [D].
NOTE: Do not turn the image position sensor shaft [E]. If the shaft is
turned, the image position indicator will be affected. If the indicator
is affected, turn off the main switch, then turn it on again. This
returns the indicator to "0".
