Deterioration of print quality or marks on prints may be due the Laser Glass needing a quick and easy clean.
Cleaning the laser glass removes any debris or toner that has fallen onto the glass during operation that could be blocking the drum units. A drum unit is an electrically charged cylinder that transfers the powder onto paper and is not to be confused with the toner cartridges. It is advised that cleaning is done on the laser glass once in a while to ensure the consistency of the quality of your prints.
