AR-5520 SIMULATIONS 7-16
46 11 Copy exposure level adjustment,
individual setting (Photo) 600dpi
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).
(Example)
[b50] [%] key [c50] [%] key [b50] [%] key [c50] •••
* Select the adjustment level with the [Light and Dark] keys.
The density LED 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.

(300dpi)AUTO indicator & TEXT
indicator & PHOTO indicator
Used to adjust the contrast for each mode.
(Operating procedure)
When 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)
