### Learn About The Drum Unit

Model name

LD2451

A new drum unit can print approximately 12,000 A4 or Letter 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, Lenovo 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.

NOTE
  - If an unpacked drum unit is placed in direct sunlight (or room light for long periods of time), the unit may be damaged.

  - There are many factors that determine the actual drum life, such as the temperature, humidity, type of paper, type of toner used and so on. Under ideal conditions, the average drum life is estimated at approximately 12,000 pages. The actual number of pages that your drum will print may be significantly less than this estimate.

    Because we have no control over the many factors that determine the actual drum life, we cannot guarantee a minimum number of pages that will be printed by your drum.

  - For best performance, use only Lenovo Original toner. The machine should be used only in a clean, dust-free environment with adequate ventilation.

    Printing with a non-Lenovo drum unit may reduce not only the print quality but also the quality and life of the machine itself. Warranty coverage does not apply to problems caused by the use of a non-Lenovo drum unit.
