3.4.1 Folding mirror alignment
Introduction
The position of the folding mirror can be adjusted by turning three screws. The folding mirror is aligned in the factory, which means
that no adjustment should be needed unless the folding mirror or the optical engine have been removed and reinstalled.
A bad alignment of the folding mirror results in a light beam which is not perfectly aimed on the DMD. The DMD will not be fully
covered by the beam, resulting in dark borders on the screen.
