46 11 Copy exposure level adjustment,<br />
individual setting (Photo) 600dpi<br />
Details of operation<br />
Used to adjust the shift amount and the inclination value for each density level (1 ~ 5) when the<br />
exposure mode is the PHOTO mode<br />
•The shift amount is the same as the gamma (gradation), and is used to set the overall brightness.<br />
When the shift amount is increased, the overall brightness is decreased.<br />
When the shift amount is decreased, the overall brightness is increased<br />
•The inclination value changes the gamma (gradation).<br />
When the set value is increased, the gamma is increased to increase the contrast.<br />
(Cle<strong>ar</strong>er black and white images)<br />
When the set value is decreased, the gamma is decreased to decrease the contrast.<br />
(Increased gradation)<br />
* Press the [%] key to switch between the shift amount and the inclination value.<br />
The 7-seg display shows the mode.<br />
The initial display is "Shift."<br />
Shift is indicated as "b" (Brightness).<br />
Inclination is indicated as "c" (Contrast).<br />

* Select the adjustment level with the [Light and D<strong>ar</strong>k] keys.<br />
The AUTO/TEXT/PHOTO indicators displays the selected level (Exp. 1 ~ Exp. 5)<br />

* Change the shift amount and the inclination value with the Numeric keys.<br />
The set range is [1] ~ [99]. The default is [50].<br />
Change the set value and press the [START] key, and a copy is made at the set value.<br />
Used set for the following three exposure modes. Enter a code number and press the [START] key,<br />
and the entered number is written into the EEPROM and the machine goes into the sub code entry<br />
standby mode. (When the [AUTO/TEXT/PHOTO] key is pressed, the number is written into the<br />
EEPROM and the set item is changed.)<br />
<br />
When this simulation is executed, the current set code number of gamma table is displayed.<br />
* When setting the gamma table, no AUTO/TEXT/PHOTO indicators <strong>ar</strong>e lighted.<br />

When the [AUTO/TEXT/PHOTO] key is pressed in gamma table setting, the mode is changed to the<br />
AUTO exposure operation mode setting and the current set code number of the AUTO exposure<br />
operation mode is displayed. (Default: 0)<br />
