Precautions for Handling Drum:

• Laser printer drums should not be exposed to light, especially direct sunlight or strong indoor fluorescent lighting, as this can damage the light-sensitive photoconductive material and degrade print quality. Extended exposure can cause issues like faint images of previous pages (ghosting), vertical stripes, or uneven print quality. 
• Be sure not to scratch the surface of the drum. When you remove the imaging cartridge from the printer, always set the unit on a clean, smooth surface. Also, avoid touching the drum, since oils from your skin can permanently damage its surface and may affect print quality.
• Do not turn the cartridge upside down or stand it on its ends.
• Avoid exposing the imaging cartridge to light and never open the drum's protective cover as this may damage the light sensitive drum. Overexposure of the drum may cause very dark or light areas to appear on printed documents and reduce its functional life.
