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.
(adjustment range: 1 – 99)

Exposure mode setup
<
γ
table setup or AE operation mode setup>
When this simulation is executed, the current setup of the gamma table code number is displayed. Enter the code number
corresponding to desired gamma table, and press the PRINT switch or the copy mode select key to enable the setup.
When the copy mode select key is pressed during setup of the gamma table, the mode is switched to the AE operation setup
mode and the current setup of the AE operation mode code number is displayed. (Default: 0) Enter the code number
corresponding to your desired AE operation mode, and press the PRINT switch or the copy mode select key to switch the
setup. (When the copy mode select key is pressed, the mode is returned to the gamma table setup mode.)
<PHOTO image process setting>
When the copy mode select key is pressed in the AE operation mode setting, the mode is changed to the PHOTO image
process setting and the currently set code number of the PHOTO image process setting is displayed. (Default: 0)
When the code number corresponding to the desired Photo image process setting is entered and the copy mode select key is
pressed, the mode is changed over.

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.
