[Function]
Used to adjust the magnification ratio in the main scan (front/rear) direction and sub scan direc-
tion.
Enter the adjustment value with [ ] [ ] key. Press [START] key to save the set value and make
a copy. (When the adjustment value is increased by 1, the magnification ratio is increased by
0.1%.)
The adjustment mode can be changed by pressing [Exposure mode selector] key.

[Operation]
The operation is similar to simulation 46-01.
[Function]
Used to display the current SPF mode sub scan direction magnification ratio on the LCD/dis-
play.
When [START] key is pressed, the entered data is acquired and saved into the EEPROM, and a
copy is made. (When the set value is increased by 1, the magnification ratio is increased by
0.1%.)
The adjustment mode can be changed by pressing [Exposure mode selector] key.
(Adjustment range: 1 – 99, Default: 50)
For printing, regardless of the density mode and the density level,
Density mode = TEXT
Density level = 3

[Operation]
The operation is similar to simulation 46-01.
[Function]
When this simulation is executed, "d" is displayed on the display, the machine goes into the pro-
gram writing mode from PC to Flash ROM.
Use the writing tool on the PC and write the program.
During writing, the display shows as follows:
