Abstract
A technique for adjusting the laser beam in a laser printing system in a simplified, inexpensive manner. The system includes an acousto-optic modulator having a transducer associated therewith. The electronic video stream is mixed with the signal generated by the carrier oscillator, the mixer output being amplified and then applied as a driver signal to the transducer. Means are provided to allow the frequency of the oscillator to be adjusted such that the position of the deflected beam is correspondingly adjusted until the unbalance of the laser beam power at the recording medium due to tolerance build-up between the system components is minimized thereby significantly extending the life of the laser.
