Background fogging (the background of a printed page is tainted by a specific colour) can be caused by an issue with one specific Toner Cartridge, the PHD Unit or a problem with the development process when Printing.
In order to diagnose a background fogging issue, please follow the steps below:
Power the Printer on and Print a Settings Report
To Print a settings report:
Press the Menu Button
Select System Settings Page
The Report now Prints
If the fogging issue is present on the Settings Report please try the following routine maintenance options:
Clean the Developer
Refresh the Toner
Refresh the Drum
Use the article below for detailed information on how to carry out the routine maintenance options:
If the Background fogging issue is still present after carrying out the maintenance options, please try another PHD Unit, if available
If after replacing the PHD Unit (or none was available), the Fogging issue is still present, please try a Stop Test on the Fuser Unit, to determine if the issue occurs before or after passing through the Fuser
If the issue is present only after passing through the Fuser Unit, please try another Fuser from a working 2150cn/cdn Laser printer (if available)
If the issue occurs before the Fuser or no other Fuser unit was available please contact Dell via Twitter to advise of a technical issue
If you require further assistance or wish to give us feedback, please engage our technical team on Twitter.
