Cannon Pixma IP3000



I have had my Cannon Pixma 3000 printer now for approx 2 years, But i have a fault dealing with CD printing.
I know it is not a fault with the printer but probably something i have done but cannot find the problem hence the reason i am here.
Ok everytime i go to print onto a CD whether black images or text on either silver or white media i am finding that it is starting to print in red rather then the detined colour? As soon as i print to paper in black it prints in black as instructed. But CD or DVD printing it prints in red. I must add that this is only happening now and again.
