46 18 Image contrast adjustment (300dpi)
Used to set the image contrast in each mode.
(Operating procedure)
When this simulation is executed, warm-up and shading operations are performed and the current setup value is displayed in
two digits. (Default: 50)
Change the setup value with the copy quantity keys. Press the PRINT switch and a copy is made according to the new setup.
The greater the setup value is, the higher the contrast is. The smaller the setup value is, the lower the contrast is. Though only
EXP.3 copy is made in this simulation, the contrast levels in EXP.1 and EXP.5 are also changed. Press the CLEAR key to save
the setup and exit from the simulation mode.
Use the copy mode select key to select a copy mode. The setup value of the selected copy mode is displayed on the copy
quantity display.

20 SPF exposure correction <SPF model only>
Used to adjust the exposure correction quantity in the SPF mode by adjusting the differential of Vref voltage for the OC mode.
(Operating procedure)
When this simulation is executed, the current setup is displayed. Enter the adjustment value with the 10-key and press the
PRINT key to enable the setup and make a copy.
When the CLEAR key is pressed, the entered value is saved and the simulation mode is terminated.
∗ The greater the value is the darker the exposure is.
The smaller the value is, the brighter the exposure is.
