I've had the Canon i960, which I use exclusively for photo printing, for about 6 months. No problems until today. My wife was printing some pics last week and a box popped up and told her it was out of ink. I went down to Staples and purchased a cartridge of Staples brand yellow, photo magenta and photo cyan. Replaced the old cartridges with the new. Didn't have any more pictures to print, so I didn't use it until today. I've printed about 10 different pictures, all with a lot of white in them. All the pictures have printed perfectly, but with a really bad magenta tint to them. It doesn't appear to be getting any better or worse, I've printed off several pictures twice and they look exactly the same. I tried the deep cleaning, still the same. Anybody have any suggestions? Cheap Staples ink?
