Step 7 ñ Adjust Image Geometry
The projection head module is mounted to a uniquely designed 6-axis adjustment
mechanism that is used during the setup process to fine-tune the geometry of the
image. It does this by moving the module about the X, Y and Z-axes in varying
degrees. How closely the image appears to match between screens is determined by
the quality of adjustments made during this step in the setup process.
To begin adjusting a wall, it is recommended that you begin with an end unit on the
bottom row then adjust the units adjacent to it. Once these are closely matched, then
move to the next unit and continue the process. Work your way across and up until
all units have been adjusted. Once you have completed adjusting the entire wall lock
the adjustments in place by tightening the four lock screws – refer to Figure 11. for
location – and the smaller set screws on the collar of each adjustment screw before
moving on to the next step.
Do not over-adjust the screws on the adjuster. If you are finding it difficult
to adjust the adjuster, it is probably because you have reached the end of the
adjustment range. In this case, it is recommended that you return the adjuster
back to the nominal position and begin adjustment again.
☛TIP: It is recommended that you take note of the position of the screws on the side
of the adjuster before you begin adjusting. By taking notice of where these screws are
located, you can quickly and easily return the adjuster back to its original position, if
required.
How to adjust the 6-axis adjuster mechanism:
☛TIP: Refer to Figure 12. when adjusting. This
illustration identifies how to adjust the mechanism to
correct the most common geometric adjustments
required during setup for both possible projector
configurations.
1. Unlock the adjuster, by loosening the four main
lock screws (see Figure 11.) and the set screw
located on the collar of each adjustment screw.
2. Center the image on the screen, by adjusting
vertical and/or horizontal position.
