When the optional fixed-focus lens (Model No.: ET-D75LE5, ET-D75LE50) is attached, the shift cannot be adjusted.

When the projection lens is tilted in contrast with the image forming surface, tilting the front side (screen side) of the projection lens downwards 

(in the direction of the dotted arrow line), the upper side of the screen focus surface will tilt inwards and the lower side will tilt outwards as 

shown in the example.

When the entire screen surface is not uniform even if the focus has been adjusted, the lens mounter has focus adjustment screws in three 

locations.

Tool used: Hex driver or Allen wrench (diagonal 2.5 mm (3/32"))

 

f

The Allen wrench is included with the projection lens ET-D75LE6, ET-D75LE8.

Focus adjustment screws (a), (b), and (c) can be turned to move the lens mount bracket back and forth.
Also, tightening the fixed screws locks the lens mount bracket in place so it does not move.
When a projection lens with a large weight is installed, or when the projector is installed on an inclination, the lens may tilt and the focus may 

become unbalanced. In these cases, perform adjustment by referring to the relationship between the adjustment location and adjustment 

screws.
