Section 4: Parts and Module Replacement

4.12.3 Fold Mirror

If a corner or edge of the image is missing (after prime lens offset is ruled out), this
may indicate the fold mirror has become misaligned with the rest of the optical
system, resulting in cropping of the projected image.
1. Use a 1.5 mm hex driver to unlock the (2) setscrews.
2. Use a 2.5 mm hex driver to adjust both cap screws, which pivot the fold mirror
back and forth.
3. Once the fold mirror is properly aligned, tighten the (2) setscrews.

4.12.4 Integrator

1. Remove the top cover. See
2. Power on the projector and display a white test pattern.
3. Locate the integrator adjustment knob.
4. Use a 6 mm wrench to loosen the adjustment knob.
5. Adjust the integrator tilt by moving the adjustment knob up or down
to create an obvious tilt on the image, so that shadows appear at each
corner of the screen.
6. Move the adjustment knob forward and backward to adjust the best focus on these shadowed edges.
7. Move the adjustment knob up and down to square the integrator rod to the projector, ensuring the shadows
at each corner disappear.
NOTES: 1) Take care to maintain the best focus on the shadowed edge while performing this adjustment.
2) Further adjustment of the fold mirror may be required if all the shadows cannot be eliminated from
every corner.
8. Once satisfied with the adjustments, use a 6 mm wrench to carefully tighten the adjustment knob.
