Used to set the AUTO exposure and the limit value at AUTO exposure (toner save).The set range is
0 ~ 255. The default is 0.
Change the setting and press the [START] key, and it will be written into the EEPROM and the
machine will go into the sub code input standby mode. When the [AUTO/TEXT/PHOTO] key is
pressed, the machine goes back to the gamma table setting mode.

<Remark>
When SIM26-60 (Destination setting) and SIM46-19 (Auto exposure mode) are changed, this set
content of this simulation is also changed to the default.
Used to adjust clear/shading of image 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: 1)
Change the set value and press the [START] key, and a copy is made according to the set value.

Used to adjust the magnification ratio in the main scanning direction (front/rear) and the sub
scanning direction.
Enter the adjustment value with the Numeric keys and press the [START] key, and the entered value
is saved a copy is made.
(When the set value is increased by 1, the magnification ratio is increased by 0.1 %.)
(Adjustment range: 1 ~ 99, Default: 50)

The current SPF/RSPF mode sub scan direction magnification ratio adjustment value is displayed.
When the [START] key is pressed, the entered value is acquired and saved into the EEPROM, and a
copy is made. When the [CA] key is pressed instead, the simulation mode is terminated.
In RSPF adjustment, after the machine enters the copy mode of one page, select the single copy
mode with the [ORIGINAL TO COPY] key to shift to the single copy mode, making two pages of
single copy.
For printing, regardless of the density mode LED and the density level LED display, the density mode
= MANUAL, and density level = 3.
