3.11 Scheimpflug adjustment procedure
CAUTION:
A Scheimpflug adjustment should only be carried out by properly qualified and
experienced projection specialists. A poor Scheimpflug adjustment may result in an extremely
degraded image and will require factory
—
servicing to the projector.
Required tools
•
Allen key, hex size 4
•
Allen key, hex size 6
Preparation
1.
Prepare the test area. Barco recommends a projector-screen distance of 2 metres be used for all
Scheimpflug adjustments.
Verify that the throw ratio of the installed lens matches the requirements of the installation area (projection
distance and screen size).
2.
Check that the lens is correctly installed, and lens shift is in centre position.
3.
If the installed lens has Iris control, open the Iris all the way up.
4.
Open the focus ring all the way up.
5.
Go to Main Menu / Test Patterns / Full Screen and select to display the Focus test pattern.
6.
Zoom the lens to its widest opening (maximum image size on the screen).
Apply a Scheimpflug correction
1.
Loosen the three set screws (reference 1b, 2b, 3b). Use a size 6 hex key to do this.

2.
Adjust the left side Scheimpflug adjustment screw (reference 1) until the test image in the top right side of
the screen is in focus. Use a size 4 hex key to do this.
Note:
This process may cause the other areas of the image to slide out of focus. This is totally normal.
