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.

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

When developer is replaced, be sure to perform the color balance
adjustment.
When not replacing the developer, do not execute SIM25-2.
