Kyocera ECOSYS P4040dn
Service Mode. New Developer, Auto Drum Refresh
New Developer
Description
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 cursor up/down keys.
3. Press the OK key.
4. Select the [YES] using the left select key. [Accepted] is displayed. After turning the power supply switch OFF / ON, the toner installation mode is executed.
* : Toner supply is stopped when the power supply SW is turned off during the execution in toner installation mode.
Auto Drum Refresh
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 Setting menu.
2. Select [Auto Drum Refresh] using the cursor up/down keys.
3. Press the OK key.
4. Select the desire mode (Off/Short/Standard/Long) using the cursor up/down keys.
5. Press the OK key. The new value is set.
