Maintenance
Adjusting the Transfer Roller
The bias voltage applied to the Transfer Roller (BTR) controls how the toner
transfers from the drum to the paper. The bias is set for each paper type that is
selected and used in the printer. If the bias voltage is too low, the toner does not
transfer properly, producing light colors and white spots. If the bias voltage is too
high, mottling of the image can occur.
To adjust the BTR:
1. Identify the paper type loaded in the paper tray.
2. Check the corresponding Paper Type is selected in the print driver Printing
Preferences.
3. On your computer, click Start > All Programs > Xerox Office Printing > Phaser
3010/3040 > Printer Setting Utility.
4. Click the Printer Maintenance tab, then select Adjust BTR from the list.
5. Click the arrow for the drop-down list to the right of the paper type.
6. Select the bias offset to adjust the BTR for the selected paper type.
Select a more positive value to increase the bias voltage.
Select a more negative value to decrease the bias voltage.
7. Click Apply New Settings to change the setting.
8. Continue printing.
Adjusting the Fuser
The Fuser uses heat and pressure to bond the toner image to the paper. For
optimal print quality, the printer automatically adjusts the temperature of the
Fuser when you change the paper type. Because of differences in paper
construction and thickness, the adjustment made by the printer is not enough or is
too much for all paper types. If the Fuser temperature is too low, the toner will not
properly bond to the paper. If the Fuser is too hot, the paper can curl.
To adjust the Fuser:
1. Identify the paper type loaded in the paper tray.
2. Make sure that the corresponding Paper Type is selected in the print driver
Printing Preferences.
3. On your computer, click Start > All Programs > Xerox Office Printing > Phaser
3010/3040 > Printer Setting Utility.
