Used to adjust the shift amount and the inclination value for each density level (1 ~ 5) when the exposure mode is
the PHOTO mode
- The shift amount is the same as the gamma (gradation), and is used to set the overall brightness.
When the shift amount is increased, the overall brightness is decreased.
When the shift amount is decreased, the overall brightness is increased
-The inclination value changes the gamma (gradation).
When the set value is increased, the gamma is increased to increase the contrast.
(Clearer black and white images)
When the set value is decreased, the gamma is decreased to decrease the contrast.
(Increased gradation)
* Press the [%] key to switch between the shift amount and the inclination value.
The 7-seg display shows the mode.
The initial display is "Shift."
Shift is indicated as "b" (Brightness).
Inclination is indicated as "c" (Contrast).

* Select the adjustment level with the [Light and Dark] keys.
The AUTO/TEXT/PHOTO indicators displays the selected level (Exp. 1 ~ Exp. 5)
* Select PHOTO(Error diffusion) or PHOTO(Dither) with the [AUTO/TEXT/PHOTO] key

* Change the shift amount and the inclination value with the Numeric keys.
The set range is [1] ~ [99]. The default is [50].
Change the set value and press the [START] key, and a copy is made at the set value.
Used set for the following three exposure modes. 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. (When the
[AUTO/TEXT/PHOTO] key is pressed, the number is written into the EEPROM and the set item is changed.)
<<Gamma table setting>>
When this simulation is executed, the current set code number of gamma table is displayed.
* When setting the gamma table, no AUTO/TEXT/PHOTO indicators are lighted.
Code number
1 Image quality priority mode
2 Toner consumption priority mode
* If this setting is changed, the set content of SIM46-30 is reset to the default.
<<AUTO exposure mode>>
When 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)
* When setting the AUTO exposure operation mode, the AUTO indicator is lighted.
Code number
0 Lead edge stop
1 Rear time process
<Photo image process setting>
When 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.
* When in the photo image process setting, the [Photo mode lamp] is lighted.
Code number

Used to adjust the exposure correction amount in the RSPF mode (for the OC mode).
(Operating procedure)
When 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.
When the [INTERRUPT] key is pressed, the entered value is saved and the machine goes into the sub code entry
standby mode. When 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.
