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

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/Setup/Operation data output/
Check (Display/Print)
Function (Purpose) : Used to check data related to the toner
density correction result. (This simulation
allows to check that the correction is nor-
mally performed or not.)
Section : Process (Developing)
Item : Operation
Operation/Procedure
1) When the machine enters Simulation 44-16, the screen on the
right is displayed.
Specify the color with [K][C][M][Y] buttons. (In this example, [K]
is selected.) The data of the selected color are displayed.
* Only one color button can be selected. When a color button
is selected, it is highlighted. (Black ([K]) is selected in the ini-
tial state.)
