Operation/Procedure
1) Press [EXECUTE] key.
2) Press [YES] key.
The service mode password is initialized.
If the password of Web page is forgotten, execute this simulation to
set the password to "service" (default).

Purpose Operation test/check
Function (Purpose) Used to check the operations of the devel-
oping section.
Section Process (Developing section)
Operation/Procedure
1) Select the process speed with [MIDDLE], [LOW] keys.
2) Press [EXECUTE] key.
The developing motor and the OPC drum motor rotate for 3
minutes and the output level of the toner density sensor is dis-
played.
TCD_K Toner density sensor K
TCD_C Toner density sensor C
TCD_M Toner density sensor M
TCD_Y Toner density sensor Y
TCV_K Toner density sensor control voltage level K
TCV_C Toner density sensor control voltage level C
TCV_M Toner density sensor control voltage level M
TCV_Y Toner density sensor control voltage level Y
NOTE: The toner cartridge must be removed before executing this
simulation.
If this simulation is executed with the toner cartridge
installed, toner will be forcibly supplied to the developing
unit, resulting in overtoner and a trouble.

Section
Operation/Procedure
1) Select a color to be adjusted with the touch panel.
2) Press [EXECUTE] key.
The developing motor rotates for 3 minutes, and the toner density
sensor makes sampling of the toner density. The detected level is
displayed.
After stopping the developing motor, the average value of the toner
density sampling results is set as the reference toner density con-
trol level.
NOTE: When the above operation is interrupted on the way, the
reference toner concentration level is not set. Also when
error code of EE-EC, EE-EL or EE-EU is displayed, the ref-
erence toner density level is not set normally.
Do not execute this simulation except when new developer is sup-
plied. If it is executed in other cases, undertoner or overtone may
occur, causing a trouble.
