Abstract:
A method for compensating misalignment errors associated with a laser beam in an electrophotographic (EP) device is disclosed. A first value and a second value of a time-of-flight of the laser beam are determined. The second value of the time-of-flight is associated with a current value of SOS time and EOS time of the laser beam. The second value of the time-of-flight of the laser beam is compared with the first value of the time-of-flight. A duty cycle of a fuser of the EP device is monitored. An average value of the duty cycle of the fuser for a predetermined time period is determined. One or more alignment conditions of the laser beam are adjusted based on at least one of the comparisons of the second value and the first value of the time-of-flight of the laser beam, and the determined average value of the duty cycle of the fuser.
