The following handling precautions must be observed:

  • The photoconductor unit (PCU) weighs 2.8kg (6.16 lb). Be sure to hold it firmly by the handle when carrying it.

  • The PCU is light-sensitive. Avoid exposing it to light any longer than necessary.

  • Be careful not to scratch the surface of the drum and transfer belt. Also, avoid touching the drum, since oil from your skin may permanently damage its surface and affect print quality.

  • Avoid tilting the PCU.


  • Do not dispose of used consumable products in a fire, as they may explode and cause injury. Dispose of them according to local regulations.

  • Keep consumable products out of the reach of children.
