The activated lens file does not correspond with the lens mounted on the projector.

Activate a lens file which does correspond with the mounted lens or mount an other lens which correspond with the lens file you want to activate.

Corrupt lens file.

Delete the lens file and program correct lens type into communicator under Advanced/lens parameters and recreate a new lens file.

Tip: Perform a “Lens Homing” before creating a new lens file. Otherwise, if the lens is removed the existing lens file becomes useless. Setup all new lens files away from the maximum limitation of the lens zoom.

The final lens position lays very close to the mechanical limits which disable the motorized lens position.

Reposition the projector (closer to on axis) so that the lens position lays further away from the mechanical limits, or try to use another lens which range is more suitable.

Tip: Setup all new lens files away from the maximum limitation of the lens shift. It is possible that lens file was originally created at the maximum shift capabilities. Program correct lens type into communicator under Advanced/lens parameters and recreate the lens files.
