γ
table setup or AE operation mode setup
When this simulation is executed, the current setup of the gamma table code number is displayed. (Default: Japan = 1, EX Japan = 2)
Enter the code number corresponding to desired gamma table, and press the PRINT switch or the copy mode select key to enable the
setup.
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.)
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.)
20
SPF exposure correction
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.
The smaller the value is, the brighter the exposure is.
29
Image contrast adjustment (600dpi)
Used to set the contrast in each mode.
(Operation/Procedure)
When this simulation is executed, the machine performs warm-up and shading, and the current setup value is displayed in two digits.
(Default: 50)
Use the copy quantity keys to change the setup value, and press the PRINT switch to make a copy with the new setup.
The greater the setup value is, the greater the contrast is, and vise versa. Only EXP.3 copy is made, however, EXP.1 contrast and
EXP.5 contrast are also changed accordingly.
When the CLEAR key is pressed, the entered setup value is saved and the simulation is terminated.
Any copy mode can be selected with the copy mode select key. The setup value of the selected copy mode is displayed on the copy
quantity display.
(Setup range: 0 – 99)
Used to set the contrast in each mode.

When the CLEAR key is pressed, the entered setup value is saved and the simulation is terminated.
Any copy mode can be selected with the copy mode select key. The setup value of the selected copy mode is displayed on the copy
quantity display.
(Setup range: 0 – 99)
31
Image sharpness adjustment
Used to adjust the clear/shading-off of an image in each mode.
(Operating procedure)
When this simulation is executed, warm-up and shading operations are performed and the current setup value is displayed. (Default: 1)
Change the setup value with the copy quantity keys. Press the PRINT switch and a copy is made according to the new setup. When the
clear key is pressed, the entered setup value is saved and the simulation is terminated.
