ABSTRACT:
The present invention provides an intensity control device for a laser in a laser beam printer that produces a hard copy of image information by copy-processing a photosensitive surface scanned by the laser while it is in a scanning mode during which the laser is modulated by the image information. The intensity control device according to the present invention stores a first representation of a present light intensity of the laser during its non-scanning mode. It further stores a second representations of a user selected image density for a hard copy produced by the printer. The first and second representations are combined for forming a control voltage during a non-scanning mode of the laser. Finally, a current is produced that is supplied to the laser in response to the control voltage such that the intensity of light produced by the laser is dependent on both the first and second representations.
