You will need to move the chip from your old cartridge over to the new one.
Please note this toner cartridge has no chip, you will need to remove the chip from your old cartridge and install it on the new toner. (You can just slide out the old chip and slide it back in to the new cartridge.)
If you are unable to do this one of our technitions can do it for you.
Currently no new chips are avaliable to us for this model of toner cartridges. We are currenty working on getting new chips for these cartridges as soon as possible. Thank you for your understanding.
You will receive a low ink warning but will be able to print untill the new cartridge is empty.
