A photoconductor unit is a component of a laser printer that includes a photosensitive print drum. Digitized data is sent via an electrostatic charge to the photoconductor or photosensitive drum, also called the PC kit, which then distributes the ink to the paper.
The photoconductor unit is considered one of the core components of a laser printer. Printing issues, such as smearing toner, are typically caused by problems with the photoconductor unit. Some issues may be resolved by simply cleaning the photoconductor unit of excess toner or dust, but others, such as leaks or defects, may require its replacement. The photoconductor unit is sensitive to light and should be protected from it, especially sunlight.
