Temperature and humidity are displayed in hex digits
Switching can be made with [AUTO/TEXT/PHOTO] key, and the set value of the selected mode is displayed on the
number of copies display.
When the [INTERRUPT] key is pressed at that time, the machine goes into the sub code input standby mode.
When the [CA] key is pressed, the simulation mode is terminated.

When this simulation is executed, the current code number is displayed on the number of copies display.
Switching can be made with [AUTO/TEXT/PHOTO] key, and the set value of the selected mode is displayed on the
number of copies display.
At that time, the setup content is written into the EEPROM by pressing the [START] key.

When the [INTERRUPT] key is pressed at that time, the machine goes into the sub code input standby mode.
When the [CA] key is pressed, the simulation mode is terminated
Used to set the copy density for each mode.
(Operating procedure)
When this simulation is executed, warm-up and shading are operated, and the current set value is displayed in two
digits. (Default [50])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 darker the density is, and vise versa. In this case, only a copy at Exp. 3 can
be made.
When, however, the density is set darker, Exp.1 and Exp. 5 become darker, too.
If the dentistry is set lighter, Exp. 1 and Exp. 5 become lighter, too.
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.

Used to adjust the shift amount and the inclination value for each density level (1 ~ 5) when the exposure mode is
the TEXT mode (including TS)
-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
* Select the adjustment level with the [Light and Dark] keys.
The AUTO/TEXT/PHOTO indicators displays the selected level (Exp. 1 ~ Exp. 5)
* Select TEXT or TEXT (TS) 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.
