Adjust the projection lens
For RPMX-D120U Models (
1) Loosen the adjustment handle (turn
thumbwheel) on the lens barrel.
2) Slide the adjustment handle to the left or
right until you see the image focus
improving. See Figure 2.9.
3) Once the correct image focus is achieved,
lock adjustments in place re-tighten the
adjustment handle until just tight.
For RPMSP-D120U/D275U Models (
OR FIELD CURVATURE)
1) Loosen the adjustment handle (turn
thumbwheel top) on the lens barrel
for the adjustment you wish
modify. (The handle closest to the
light engine adjusts focus and the
handle closest to the glass lens
surface adjusts field curvature.)
2) Slide the adjustment handle to the
left or right until you see the image
improve. If the image requires
adjustment for both focus and field
curvature, adjust focus first. See
Figure 2.10
3) Once you have achieved the desired image, re-tighten the adjustment handle
until just tight.

Adjust image geometry using the 6-axis adjuster
The light engine is mounted to a uniquely designed 6-axis adjustment mechanism,
which can be used during setup to fine-tune the geometry of a displayed image.
The mechanism works by moving the light engine about the X, Y and Z-axes in
varying degrees.
For single projectors, adjust the 6-axis adjuster until the displayed image fills the
screen and appears without any geometric distortion. If you are setting up a
multi-projector display wall, use the 6-axis adjuster to closely match the image
across multiple screens. It is recommended you begin adjustment on an end unit
on the bottom row of wall and work your way across and up until all units have
been adjusted.
