(2) Method
• Create a dot pattern patch between images of which more than 20 prints have been run off. The laser PWM
at this time is maximum.
• Read this dot pattern patch with the IDC sensor (IDCS) and calculate the difference between the sensor
output and the specified value.
• Determine the correction amount of the laser power based on a value calculated to make corrections of the
laser power.
• Repeat several times the control operations described above.
