The dynamic range of an electrophotographic device may be shifted by
calibrating a laser power of a laser source to operate within a first
range of power levels during a laser power adjustment operation. At least
one laser control parameter is modified after calibrating the laser power
so that the laser source is operable within a second range of power
levels different from the first range of power levels and a beam emitted
by the laser source is controlled within the second range of power levels
when the beam is directed towards an image area of a photoconductive
surface.
