Yes these cartridges are refillable, however, you would also need to change the chip or get a chip resetter (as the refilled cartridges will not be recognized as full, unless the chip is replaced or reset). The new chips are $1.19 each (item number 145-169-01), and the resetter is $19.99 (item number 145-160-01), and is reusable for hundreds of resets, and works on all color chips.
