• DO NOT put a toner cartridge, a toner cartridge and drum unit assembly, or a waste toner
box into a fire. It could explode, resulting in injuries.
• DO NOT use flammable substances, any type of spray, or an organic solvent/liquid
containing alcohol or ammonia to clean the inside or outside of the product. Doing so could
cause a fire or electrical shock. Instead, use only a dry, lint-free cloth. For instructions on how
to clean the product, see User's Guide/Basic User's Guide: Routine Maintenance.
DO NOT attempt to operate this product when a paper jam or stray pieces of paper are inside
the product. Prolonged contact of paper with the fuser unit could cause a fire.
DO NOT use a vacuum cleaner to clean up scattered toner. Doing this might cause the toner
dust to ignite inside the vacuum cleaner, potentially starting a fire. Please carefully clean the
toner dust with a dry, lint-free soft cloth and dispose of it according to local regulations.
