Optical Axis Adjustment - Ricoh Sirius-PJ1 nx Service Training

Optical Axis Adjustment - 1

It is best to do this procedure in a dark room.
Turn on the projector.
In the SOURCE menu, display a white test pattern.
Check for shadows at the edges of the display. During the adjustment, we must try to
get rid of the shadows as much as possible.
If shadows appear at the top and bottom edges [A], adjustment is needed in the
vertical direction.
If shadows appear at the left and right edges [B], adjustment is needed in the
horizontal direction.
The color of the shadows at the edges tells you which colors must be adjusted.
Cyan-like shade: R is missing at the edges and must be adjusted
Yellowish: B is missing at the edges and must be adjusted
Magenta-like shade: G is missing at the edges and must be adjusted
Reddish: G and B are missing at the edges and must be adjusted
