Blue ink - printing problem

Hi there,

Having a problem with the blue ink in our Canon MP830. We only use Canon ink cartridges and printing has been fine. A few days ago however, I whenever I print anything that has blue in it it prints stripey. I went through the usual printer head cleaning, deep header cleaning etc but nothing seems to make it work. When you open the lid it does look like the blue ink might have burst at some time as there seems to be splodges of blue ink inside the printer (this dry however!!).

Not sure what else to try!
