How do I fix my ink cartridges so that my pictures come out right and not with a yellow or pink tint?

I am using a Canon i960 photo printer. Before, my pictures were printing with a pink tint. I then changed all of my ink cartridges thinking the problem resulted from the low ink cartridges. After I changed them my pictures started printing with a yellow tint. What am I suppose to do to fix this? I need my printer to print pictures.
