MX3500N SIMULATION 7 – 61
44-12
Purpose Adjustment/Setup/Operation data output/
Check (Display/Print)
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.)
Section Process
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.
<Display item and content description>
* 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.
<Operation contents>
1) The target value of CL is set and the LED emitting level is
adjusted, and the operation is terminated.
