Replacing the Toner Cartridge
The toner cartridge contains the image drum and toner supply of the printer. It should be replaced
after approximately 15,000 sheets have been printed (rated at Letter/A4 size, single-sided, 5% black
coverage). Depending on operating conditions and the type of print jobs being output, however, the
cartridge may need to be replaced before or after that interval is reached. Instructions for
replacement of the toner cartridge are as follows:
Toner Handling Precautions:
• Do not expose the cartridge to direct sunlight or other strong light sources.
• Do not replace the cartridge under bright lighting conditions. Complete the installation as quickly as
possible (within 5 minutes of opening the protective foil shipping bag).
• Do not open the drum shutter by hand. The drum shutter protects the photosensitive image drum
from external light.
• Never touch the surface of the photosensitive drum. Keep the cartridge level, do not turn it over or
stand it on end.
• If toner comes into contact with your hands or clothing, wash it off with cold water. Exposure to
toner is not harmful, however hot water will melt and set the toner, causing staining.
