Function (Purpose): Used to check the sampling toner image
patch density data in the image forming
section correction (high density process
correction). (This simulation is used to
check whether the correction is normally
executed or not.)

Item: Data (Machine condition)
Operation/Procedure
1) Change the page with [↑] [↓] buttons.
* If there is a page over [↑], an active display is shown and the
page moves up. If there is no page upward, the display
grays out and the operation is invalid.
If there is a page under [↓], an active display is shown and
the page moves down. If there is no page downward, the
display grays out and the operation becomes invalid.
2) Change the display with the following buttons:
[TARGET] button: Display of each color target
[PATCH] button: Display of patch sampling data
* When [CLOSE] button is pressed, the display shifts to the copy
basic screen of simulation.
* Copying can be performed also by pressing [COLOR]/[BLACK]
key.
* PATCH item: If the patch is converged to the target range in less
than 10 times of patch acquisition, 0 is displayed in the other
display items.
* When [PATCH] button is pressed, the following page is dis-
played.
• n = 1 to 2 Page 1
• n = 3 to 4 Page 2
• n = 5 to 6 Page 3
• n = 7 to 8 Page 4
• n = 9 to 10 Page 5

Purpose: Adjustment
Function (Purpose): Color image density sensor adjustment
(Adjustment by the jig)
Section:Process
Item: Operation
Operation/Procedure
1) When [EXECUTE] button is pressed, it is highlighted, and the
color sensor adjustment is started by using the patch seal.
* After completion of the color sensor adjustment, [EXECUTE]
button returns to the normal display, and the set content is
displayed. At that time, the necessary data are saved to
EEPROM and RAM.
* When [EXECUTE] button is pressed during the sensor
adjustment, the sensor adjustment is interrupted and [EXE-
CUTE] button returns to the normal display.
* In case of an adjustment error, ERROR is displayed in the
value display section at the right of the error item. No data
are saved to EEPROM, and the operation is terminated.
[EXECUTE] button returns to the original state.

1) The target value of CL is set and the LED emitting level is
adjusted, and the operation is terminated.

 
44-14
Purpose: Adjustment/Setup/Operation data output/
Check (Display/Print)
Function (Purpose): Used to check the output level of the fusing
temperature sensor, the machine tempera-
ture sensor, and the humidity sensor.
Section:Process
Item: Operation
Operation/Procedure
1) The machine enters this simulation, the current data are dis-
played.
* If there is a page over [↑], an active display is shown and the
page moves up. If there is no page upward, the display
grays out and the operation is invalid.
If there is a page under [↓], an active display is shown and
the page moves down. If there is no page downward, the
display grays out and the operation becomes invalid.
* Data are revised every 5sec.
* For the temperature and humidity only, data outside the range
are displayed as -.
* The above display range is converted into hexadecimal number
to display the AD value.
* When the door open, the power of the sensor would be down, so
that the sensor display is treated as outside the range.
*°C is displayed as deg on the panel because of the display
fonts.

Purpose: Adjustment
Function (Purpose): Used to perform the phase adjustment for
OPC drum deflection. (Used to adjust the
phases of four OPC drums deflection.)
Section: Process (OPC drum)
Item: Adjustment
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 3 with 10-key in the print mode of set item A to change
the set value. (Default is 3.)
* Press [C] key to clear the entered values.
3) Set A3 paper in the cassette 1 tray.
4) Use [↓] button to shift to the paper of set item C and enter 3
with 10-key. (The default is 3.)5) When [OK] button is pressed, it is highlighted and the current
set value is saved to EEPROM and RAM.
* When [EXECUTE], [↑], [↓], [COLOR], or [BLACK] key is
pressed, the current set value is saved to EEPROM and
RAM.
6) Check the output pattern to examine deflections of C, M, Y,
and K.
• The deflection is within 2 lines. → Simulation is completed.
• The deflection is not within 2 lines. → Go to step 9.
7) Shift to the set item A and enter 1 with 10-key.
8) When [EXECUTE] button is pressed, the drum deflection
adjustment pattern is printed. (8 sheets are outputted.)
* Numbers 1 – 8 are printed sequentially in the output pattern.
9) Check 8 sheets of print patterns to find the print pattern in
which the deflection is within2 lines for C, M, and Y. Set the
print value of the print pattern to set item B.
10) To check the deflection in the set value, enter 3 to set item A
with 10-key, and press [EXECUTE] button to print one sheet of
the drum deflection adjustment pattern.
* When [C], [CA], [SYSTEM SETTINGS], or [EXECUTE] button is
pressed during self print, the operation is interrupted.
* After completion of self print, [EXECUTE] button returns to the
original state.
* For cassette selection, the manual feed cassette is set. (Set item
C is 1)

* The display of item A/C is Display item: Detail of display.
