Replacing The Toner Cartridge
NOTE: Wear vinyl gloves to prevent toner from contacting the skin.
Use only cold water to remove toner from skin or clothing.
Put the old cartridge in a disposable wrapper (a plastic bag,
paper towels, newspaper) to minimize toner spillage.
1. Take the printer off line.
2. When paper motion stops, wait 15 seconds, then open the
printer upper doors.
