New Developer
Contents
The new developing unit is shipped from the factory with no toner contained. The developing unit 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 developing unit 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 developing unit needs
approximately 200 g for triggering the sensor inside.)
Purpose
To execute when the developing unit has been replaced.
Method
1 Enter the Service Setting menu.
2 Select [New Developer] using the ［▲］［▼］ keys.
3 Press the [OK] key.
4 Select the [YES] using the left select key.
5 [Accepted] is displayed.
6 The toner installation is performed when power is turned on and off.
• Toner supply is stopped when toner installation mode is performing.
Completion
Press the [Stop] key.
Auto Drum Refresh
Contents
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 Setting menu.
1 Select [Auto Drum Refresh] using the ［▲］［▼］ keys.
2 Press the [OK] key.
3 Select the desire mode (Off/Short/Standard/Long) using the ［▲］［▼］ keys.
4 Press the [OK] key. The new value is set.
Completion
Press the [Stop] key.
