(4) The message “Has developer in the developer unit run out?” appears on the display.
If there is no problem, press the [Yes] button on the display.
(5) The message “Have the [**] developer cartridges been installed?” appears on the display. If there
is no problem, press the [Yes] button on the display. Tip: “**” varies as follows depending on the
code you have entered.
Be sure that the developer cartridge is completely empty before you press [Yes]. If you press
[Yes] while developer material still remains in the developer cartridge, it will overflow and thus
may lock the developer unit.
(6) The message “Supplying developer.” appears on the display and developer material is filled in
the developer unit for approx. 90 sec.
For example, if the filling of the Y and M color developer materials fails, the following screen is
displayed. Press the [OK] button, turn the power OFF and check the developer unit.
