Learn About The Drum Unit

A new drum unit can print approximately 12,000 Letter or A4 size single-sided pages.
Drum wear and tear occurs due to use and rotation of the drum and interaction with paper, toner and other
materials in the paper path. In designing this product, Dell decided to use the number of rotations of the drum as a
reasonable determinant of the drum life. When a drum reaches the factory-established rotation limit corresponding
to the rated page yield, the product's LCD will advise you to replace the applicable drum. The product will continue
to function; however, print quality may not be optimal.
