Lens shift range
The projector can adjust the position of the projected image within the lens shift range for each projection lens
based on the optical center position of the image (standard projection position). Optical center position of the
image is an image position based on the optical axis center of the projector body.
Perform the lens shift adjustment within the range indicated in the following illustration. Note that moving the lens
outside the adjustment range may change the focus. This is because the shift of the lens is restricted to protect
the optical parts.
Following illustration indicates the lens shift range when the projector is installed on desk/floor.
