operation mode.
Section:Fusing
Item: Operation
Operation/Procedure
1) Select the set item with [↑] and [↓] buttons.
The highlighted set value is switched and the value is dis-
played in the setting area.
* If there is any item over [↑], an active display is made and
item is shifted.
If there is no item over [↑], the display grays out and the
operation is invalid.
If there is any item under [↓], an active display is made and
item is shifted.
If there is no item over [↓], the display grays out and the
operation is invalid.
2) Enter the set value with 10-key.
* Press [C] key to clear the entered values.
3) When [OK] button is pressed, the currently entered data are
saved to EEPROM and RAM.
* When [↑], [↓] button, [COLOR], or [BLACK] key is pressed,
the current set values is saved in EEPROM and RAM.

Purpose: Setting
Function (Purpose): Used to correct the environments of low
temperature and low humidity (L/L) for the
fusing temperature setting 1 for each paper
(SIM 43-01).
Section:Fusing
Item: Operation
Operation/Procedure
1) When the machine enters Simulation 43-20, the screen on the
right is displayed. (The current set value is displayed.)
2) Select the set item with [↑] and [↓] buttons.
The highlighted section of the set value is switched and dis-
played on the set setting area.
* If there is any item over [↑], an active display is made and
item is shifted.
If there is no item over [↑], the display grays out and the
operation is invalid.If there is any item under [↓], an active display is made and
item is shifted.
If there is no item over [↓], the display grays out and the
operation is invalid.
3) Enter the set value with 10-key.
* Press [C] key to clear the entered values.
4) When [OK] button is pressed, the currently entered data are
saved to EEPROM and RAM.
* When [↑], [↓], [COLOR], or [BLACK] key is pressed, the cur-
rent set value is saved to EEPROM and RAM.
* Input value: The intercept for the correction value is 50. This is
because the set value is kept as a positive number in case of a
negative setting due to negative correction.
• Correction value: (–49 to +49) Input value: Actually entered value
(1 to 99)

The highlighted section of the set value is switched and dis-
played on the set setting area.
* If there is any item over [↑], an active display is made and
item is shifted.
If there is no item over [↑], the display grays out and the
operation is invalid.
If there is any item under [↓], an active display is made and
item is shifted.
If there is no item over [↓], the display grays out and the
operation is invalid.2) Enter the set value with 10-key.
* Press [C] key to clear the entered values.
3) When [OK], [↑], [↓] button, [COLOR], or [BLACK] key is
pressed, the entered value is set.
* Input value: The intercept for the correction value is 50. This is
because the set value is kept as a positive number in case of a
negative setting due to negative correction.
• Set value: Value to be set (–49 to +49)
Input value: Actual input value (1 to 99)

* On adjustment values
Each temperature correction value → Temperature 1°C change
by 1 count
Each paper exit count → 1 sheet by 1 count
Each cool-down time → 1s change by 1 count

Purpose: Setting
Function (Purpose): Used to set whether the correction func-
tions of the image forming (process) sec-
tion are enabled or not.
Section:—
Item:—
Operation/Procedure
1) When the machine enters Simulation 44-01, the currently set
button is highlighted.
Set the item to be set to the normal display.
(Two or more items can be selected.) When an item is
selected, its button is highlighted. When the highlighted button
is pressed again, it returns to the normal display.
2) When [EXECUTE] button is pressed, the current set value is
saved to EEPROM and RAM. After completion of setting,
[EXECUTE] button returns to the normal display.
*1: The transfer efficiency fluctuation is corrected with temperature 
and humidity (absolute moisture). YES/NO setting. Transfer 
high output voltage correction.

Purpose: Adjustment
Function (Purpose): Used to perform the light quantity adjust-
ment of the process control sensor and the
registration sensor (two for resist are
adjusted simultaneously) and the surface
scan.
Section: Process
Item: Operation
Operation/Procedure
1) When [EXECUTE] button is pressed, it is highlighted and all
the drum motors are driven to start the adjustments of the pro-
cess control sensor and the registration sensor.
* After completion of the adjustments of the process control
sensor and the registration sensor, the drum motors are
stopped and the set contents are displayed. The necessary
data are saved to EEPROM.
[EXECUTE] button returns to the normal display.
* When [EXECUTE] button is pressed during adjustment of
the process control sensor and the registration sensor, the
monitor is terminated and the drum motor is stopped. [ECE-
CUTE] button returns to the original state.
Data saving is not performed, but the result at that time is
displayed.
* When an error occurs in the adjustment, ERROR is dis-
played in the value display section at the right of the error
item, and the drum motor is stopped. Data saving to
EEPROM is not performed at all and the operation is termi-
nated. [EXECUTE] button returns to the original state.
* When there is a page over [↑], the display becomes active
and shifts up to another page. When there is no page over
[↑], the display grays out and the operation is disabled.
* When there is a page under [↓], the display becomes active
and shifts down to another page. When there is nor page
under [↓], the display grays out and the operation is dis-
abled.

Operation/Procedure
1) When the machine enters SIM 44-06, the screen shown on the
right is displayed.
2) When [EXCECUTE] button is pressed, it is highlighted and all
the drum motors are driven to rotate. The high-density process
control is started.

4) After completion of the high-density process control, the drum
motors are stopped and [EXECUTE] button returns to the nor-
mal display.When the operation is completed normally, COMPLETE is
displayed and the execution result is saved to EEPROM and
RAM.
In case of an error, ERROR is displayed and the details of
the error are displayed below.
* When the high-density process control is interrupted by an
external factor (pressing [EXECUTE] button), the forcible
interruption screen is displayed and the drum motors are
stopped. [EXECUTE] button returns to the normal display.
