Take out all of the toner cartridge and drum unit assemblies.
IMPORTANT
• We recommend that you place the toner cartridge and drum unit assemblies on a clean, flat surface with
disposable paper underneath them in case you accidentally spill or scatter toner.
• To prevent damage to the machine from static electricity, DO NOT touch the electrodes shown in the
illustration.
• Handle the toner cartridge carefully. If toner scatters on your hands or clothes, immediately wipe or wash
it off with cold water.
• To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.
