Used to adjust the contrast for each mode.
(Operating procedure)
When this simulation is executed, warm-up and shading are performed, and the current set value is displayed in
two digits. (Default: 50)
The AUTO/TEXT/PHOTO indicators is lighted.
Change the set value and press the [START] key, and a copy is made according to the set value.
The greater the set value is, the higher the contrast is.
The smaller the set value is, the lower the contrast is.
In this case, only a copy at Exp. 3 is made.
However, the contrasts at Exp.1 and Exp. 5 are also changed accordingly.
To select a desired copy mode, press the [AUTO/TEXT/PHOTO] key.
The selected copy mode set value is displayed on the copy quantity display.
