12-2. AE Sensor
In the Auto Exposure Mode, the AE Sensor on AE Sensor Board PWB-H measures
the intensity of the light reflected off the original, which results in the black/white
ratio of a 210-mm-wide area from the reference position of the original being
measured. According to this measurement, the Exposure Lamp voltage is
automatically increased or decreased so that copies of consistent quality are
produced.
The output from the AE Sensor is applied to PWB-A which, in turn, varies the duty
ratio of the AVR Remote from it to vary accordingly the LA1 voltage.
Original Density (B/W Ratio) High Low
Intensity of Reflected Light Low High
PWB-H Output High Low
AVR Duty Increased Decreased
LA1 Voltage Increased Decreased
