4. Evaluate the sides for rotation.

6. Repeat steps 3 to 5 until proper convergence is observed.
7. Gradually tighten the four lock-down screws to lock the formatter.
•
Torque to 8 in.lb. when using a straight driver.
•
Torque to 16 in.lb. when using an angled driver.
If the convergence shifts when locking down the formatter:
a. Evaluate the amount of shift with the formatter locked.
b. To compensate for the lock-down shift, unlock the formatter board and shift the color by
the same distance as the lock-down shift, except in the opposite direction.
c. Gradually tighten the four lock-down screws to lock the formatter.
d. If convergence is still necessary, repeat the previous steps.
8. For the blue formatter, repeat steps 2 to 7.
Adjusting the fold mirror
One of the two fold mirrors has the adjustment screws located under the top cover. The cover must be
removed to adjust the mirror. The other fold mirror is located on the bottom of the projector and does
not have any adjustment screws.
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.
