Theory of Operation
309
2.
Light Density Adjustment
At the execution of automatic density control, the light density adjustment
is made just before the patches for toner density control are generated.
Light is emitted from the LED, with the current light density setting, to
check if the output value of the CTD (ADC) sensor is within the specified
range. If the output value is low light density is increased. If the output
value is high, the light density is decreased.
If the output value is less than the first lower limit, the controller signals the
sensor as dirty and generates a warning. If less than the second lower limit,
the controler signals the sensor as faulty and stops the printing.
