Gently shake the new cartridge from end to end several times to loosen and 

distribute the toner evenly inside the cartridge.

Remove the wrapping material and peel off the adhesive tape from the underside of 

the cartridge.

Holding the cartridge by its top centre with the coloured lever to the right, lower it 

into the printer over the image drum unit from which the old cartridge was removed.

10. Insert the left end of the cartridge into the top of the image drum unit first (a), 

pushing it against the spring on the drum unit, then lower the right end of the 

cartridge down onto the image drum unit (b).

11. Pressing gently down on the cartridge to ensure that it is firmly seated, push the 

coloured lever (c) towards the rear of the printer. This will lock the cartridge into 

place and release toner into the image drum unit.

12. Finally, close the top cover and press down firmly at both sides so that the cover 

latches closed.
