[QUOTE=walkerblackwell;12655]Only for best results. If you have an old cartridge that has seen a lot of life, I suggest getting a new one. If you are on a budget, dump out as much as possible and you can add the other ink in. I don’t suggest [I]mixing[/I] the inks together fully in the cart though (like 1/2-1/2 or 1/3-2/3 that isn’t recommended).
all the best,
Thank you for your quick reply, Walker, new cartridges it is!
