MG7150 printing blurred

[pjb]

I have had my MG7150 for 3 years, but now it has started printing blurred lines of text interposted with clear lines of text - see sample below. The pattern seems to repeat every 20mm or so.

I have tried head cleaning etc. but it didn't make any difference. Any ideas?

I have this issue too. Did you resolve it?
