Paper fragments, toner and dust collects on the various components inside of your Hewlett-Packard (HP) 4200 laser printer. The debris eventually soils the rollers in the printer as well as paper moving across the rollers. The drum is also not immune to debris collecting on its surface.

When cleaning the drum, you need to be careful not to damage the door and springs present on the drum. Tips Writer Bio
