Canon Primax MG5450 Been working great for around 2 years but has started to break up 1 line top third and 2 lines middle page and part of 1 line in bottom third. I have just replaced the 2 black ink cartridges, after about 30 A4 sheets & 30 A5 envelopes this has started. Can you advise please. William XXXXX
