MX-3114N ADJUSTMENTS AND SETTINGS 5 – 5
2)
Close the front cabinet.
3)
Select a developing unit to be adjusted.
4)
When [EXECUTE] key is pressed, it is highlighted. The DV
roller rotates, and the toner density sensor detects toner den-
sity, and the output value is displayed.
The above operation is executed for 1.5 minutes, and the aver-
age value of the toner density sensor detection level is set
(saved) as the reference toner density control value.
When the reference toner density control adjustment operation
is completed, [EXECUTE] key returns to normal from highlight.
This makes known about whether the adjustment operation is
completed or not.
The above operation is executed each of the lower speed
mode and the middle speed mode, and the reference toner
density control value is set for each of them.
If the operation is interrupted within 1.5 minutes, the adjust-
ment result is not reflected.
When [EXECUTE] key is pressed during the operation, the
operation is stopped and [EXECUTE] key returns to the normal
display.
If [EE-EU], [EE-EL], or [EE-EC] is displayed, setting of the ref-
erence toner density control value is not completed normally.
Troubleshoot the cause, remove the cause, and perform set-
ting again.
5)
Cancel SIM 25-2.
6)
Confirm that "Install the toner cartridge" is displayed, and
install the toner cartridge by the following procedures.
7)
Shake the toner cartridge horizontally several times.
8)
Open the front cabinet, and insert each toner cartridge.
Be sure to install the color cartridges to their proper positions.
Avoid installation to a different color position.
Do not forcibly insert the toner cartridge.
Push it in until the cartridge is securely locked in place.
Developing units removed, be sure to remove the toner car-
tridges as well to prevent toner clogging.

9)
Close the front cabinet.
10) Confirm that "Toner replenishment in progress" is displayed,
and wait until the display disappears. (It takes 30 sec - 6 min.)
This procedure is for checking the toner supply operation from
the toner cartridge to the DV unit. The operation time differs
depending on the toner quantity in the toner cartridge, uneven
distribution of toner, and the internal state of the toner car-
tridge.
Do not perform operations which interrupt the above operation,
such as opening the front cover, entering the SIM mode, and
turning OFF/ON the power. If this precaution is ignored, Trou-
ble codes F2-40 - 43 or F2-64 - 67 or a over-toned condition
may occur.
When replacing developer, always replace all the three colors of
Yellow, Magenta, and Cyan.
If only one color is replaced, color balance may be adversely
affected. Black developer can be replaced individually.
When developer is replaced, be sure to perform the color balance
adjustment.
When not replacing the developer, do not execute SIM25-2.
