Abstract
A printing apparatus having a fixed focal point for a recording medium to which the printing apparatus writes, the apparatus comprises a rotor; an intensity-modulated light source adapted to emit a light beam along an optical path; a platform having three variably positioned ball feet to which platform the light source is fixed for maintaining the positional relationship of the light source in relation to the focal point; a plate having three grooves attached to the printing apparatus which cooperatively receives the ball feet; and a housing that receives the plate and platform and cooperatively attaches to the rotatable rotor to move the light source for scanning the light beam along the recording medium, for permitting removal and replacement of the light source in a precise fashion.
