how do I open the cartridge?
Help please! I have just bought an Epson RX640 and am in the process of installing the ink cartridges, however, I'm stuck as there is a plastic film over them which refuses to budge; I assume I am supposed to remove this? A daft question I am sure but all other makes that I have used in the past have been obvious and this isn't. Thanks.
