Checking the Toner Cartridge

1. Ensure the Toner Cartridge is correctly installed and rotated into its opened
position.
2. Remove the Toner Cartridge in question.
3. Inspect the cartridge's cap to ensure it is securely taped in placed.
4. Tilt the cartridge back and forth to ensure it contains toner.
5. Rotate the Gear at the rear of the cartridge. You should hear the Auger Coil
move inside the Toner Cartridge. If the Auger Coil and Gear rotate
correctly, the cartridge is good.
