For anyone in the market for a good printer thats easily refillable consider
Brother DCP115c and similiar.Thats the reason i bought this model.
Just lift the scanner/lid, the ink wells are exposed, you can just lift them out, drill hole in the top, fill with ink, which can be seen as one side of the well is clear plastic, reinsert, close lid and the printer then asks if you have fitted new cartridges, so just click yes(3x). And Bob's your uncle!
Just refilled for the cost of about £4 in ink (15ml x 4)
