Laser printer plotter using photosensitive print material

摘要

The laser printer or plotter uses a web of sensitive material (2). This web is supplied by a magazine (1) that has a code (3) that is read (4) to identify the material type and is used to adjust the intensity of the laser. The reproduction process use a laser output (8) that is directed at a rotating polygonal mirror (9). The beam of coherent light reflected from the moving mirror is directed through a lens (11) and full width two-dimensional bar lens (12) to line scan the material.
