I was given this printer about 8 months ago and it's been working like a dream since. Although, one issue I have noticed is the colour balance seems to be slowly slipping. Originally the colours were coming out perfectly but now all my images appear to have a red/purple tint which is making my work look very odd. I've tried replacing the ink and yet this issue continues. I've just bought photo paper for it but don't want to waste it on printing oddly coloured images. Is there any way to manually change the colour balance on the printer?
