buy a set of inks with it as it uses half the ink in the carts to charge the system, the inks don't sit on top of the carriage they sit to the side and the ink is pumped to the head via tubes. another downside is that the black cart is the same size as the colours so if you print a bit of text you will go through black quite quickly, Canons on the other hand have 2 black carts, 1 big 1 for text and one smaller one just for photos.
