Kit          1

Gram      250

Tools     cartridge hole making tool , Replacement Chip Needed


Please note that the electronic “smart chip” on the outside of this cartridge reports the toner level to the machine (via radio frequency transmission). This chip will need to be replaced before the cartridge may be reused.


To replace the chip :

1.      Using a flat head screwdriver, pry out old chip.

2.      Push the new chip into place. Note : The replacement chip is backed with an adhesive to prevent it from falling out of place.


Refill Instructions :


    Turn the sealed bottle of toner upside down.
    Tap the funnel cap.
    Turn the HP LaserJet 4100n cartridge right-side-up and tap the bottom of the bottle against a counter top.

    Then, tilt the printer cartridge at an angle to gain access to the filling hole created as suggested by the diagram.

    You can now safely insert the funnel cap into the filling hole and start pouring toner into the laser HP printer cartridge.
    In case toner does not flow easily into the cartridge repeat from the beginning.

    If you believe your cartridge may have been reused a lot or there is some sort of premature cartridge failure you should only fill your cartridge from 1/3 to 1/2 of its capacity at most.

    Now seal the filling hole with duct tape.

    Finally, gently shake the cartridge from side to side

2.      Make hole (see diagram).
