Uniformly dark prints
Locate the green print density knob located along the left side of the printer. Turn the knob counterclockwise to lighten the print (less toner will be used).
note
If all printer consumables have been replaced and image defects and/or paper creases persist, the fuser may need to be replaced. The fuser is the unit that heats the toner so that it adheres to the paper. When the fuser is worn, print quality may deteriorate. On average, the fuser should provide optimum print quality for 300,000 pages when using paper rated between 16 and 25 pounds. Label stock and other heavier media may reduce the life of the fuser. Contact your authorized service representative for fuser replacement.
