Removing the lens mount

The lens mount, located at the front of the projector is an assembly of mechanical and electrical
components that securely holds and positions the projection lens.
Two motors are attached to the lens mount:
• One for vertical adjustment
• One for horizontal adjustment
The axes of motion are guided by linear shafts and bushings designed to reduce vibration and
unintended motion. Two wires for each adjustment run to the panel driver, the horizontal stepper and
position wires and the vertical stepper and position wires. A wire runs to the panel driver to control the
focus and zoom options of the lens mount.
A mounting plate, fixed to the lens and magnets within the lens mount, assists in locating the lens
against the alignment pads.
