AR-5520 SIMULATIONS 7-17
46 19 Exposure mode setting
(Gamma table setting / AUTO
exposure operation mode setting /
PHOTO image process setting) Used set for the following three exposure mode. Enter a code number and press the [START] key,
and the entered number is written into the EEPROM and the machine goes into the sub code entry
standby mode. (
W hen the [AUTO/TEXT/PHOTO] key is pressed, the number is written into the
EEPROM and the set item is changed.)
<<Gamma table settin g >>
W hen this simulation is executed, the current set code number of gamma table is displayed.
* W hen setting the gamma table, no AUTO/TEXT/PHOTO indicators are lighted.
* If this setting is changed, the set content of SIM46-30 is reset to the default.
<<AUTO exposure mode>>
W hen the [AUTO/TEXT/PHOTO] key is pressed in gamma table setting, the mode is changed to the
AUTO exposure operation mode setting and the current set code number of the AUTO exposure
operation mode is displayed. (Default: 0)
*
W hen setting the AUTO exposure operation mode, the AUTO indicator is lighted.
<Photo ima g e process settin g >
W hen the [AUTO/TEXT/PHOTO] key is pressed during the AUTO exposure operation mode setting,
the setting mode is changed to the photo image process setting and the currently set code number of
the photo image process setting is displayed.
*
W hen in the photo image process setting, the [Photo mode lamp] is lighted.
20 SPF exposure correction
(Only when the SPF/RSPF is
installed) Used to adjust the exposure correction amount in the SPF mode (for the OC mode).
(Operatin g procedure)
W hen this simulation is executed, the current set value is displayed.
Enter the adjustment value with the Numeric keys and press the [START] key.
The entered set value is stored and a copy is made.
W hen the [Interrupt] key is pressed, the entered value is saved and the machine goes into the sub
code entry standby mode. W hen the [CA] key is pressed, the entered value is saved and the
simulation is terminated. [1] ~ [99] (Center [50])
*
The greater the set value is, the darker the density is. The smaller the set value is, the lighter the
density is.
* The exposure mode is TEXT fixed. The LED does not change, either.
The exposure level can not be adjusted.
29 Image contrast adjustment
(600dpi) Used to adjust the contrast for each mode.
(Operatin g procedure)
W hen this simulation is executed, warm-up and shading are performed, and the current set value is
displayed in two digits. (Default: 50)
The density LED is not 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.
(Adjustment range: 1 ~ 99)
