Initializing the developer unit (toner install mode)
Description
The new developer unit is shipped from the factory with no toner contained. The developer
can be automatically replete with toner when a toner container is installed onto it and the
printer is turned on. However, because the toner reservoir in the developer has a large
capacity, it requires a lengthy period of time until a substantial amount of toner has been fed
to get the printer ready. (A new developer needs approximately 260 g for triggering the sen-
sor inside.)
Purpose
To execute when the developer unit has been replaced.
Method
1. Enter the service mode [>>Developer].
2. Press the OK key. [>>Developer?] will be displayed.
3. Press the OK key. [Ready] will be displayed.
4. Turn off and on the printer. [Self test] [Please wait (Adding toner)] will displayed. The
printer continually engages in this mode for a period of approximately 10 minutes,
after which the printer reverts to the [Ready] state. [Ready] will displayed. Devel-
oper initialization is finished.
Completion
Automatic drum surface refreshing
Description
The drum surface refreshing operation is normally performed when the power is turned on to
the printer or during warm-up when the printer is recovering from the Sleep mode, but even
then only at those times that the temperature/humidity sensor detects the drum surface to be
in a state of dew condensation. By using this mode, it is possible to force the drum surface
refreshing operation to be performed automatically at a predetermined period of time,
regardless of the status detected by the temperature/humidity sensor.
Purpose
To prevent bleeding of the output image when the printer's operating environment is one of
high humidity.
Method
1. Enter the service mode [>>DRUM-CTRL].
2. Press the OK key. [>>DRUM-CTRL?] will be displayed.
