Canon iP7250 clogged; deep cleaning hasn't worked

[ricecrispies]

My Canon Pixma iP7250 appears to be clogged, perhaps because it wasn't used for three or four months. On the test print there is no magenta at all, and the pigment black is sparse and sporadic. I've run a deep clean, but this hasn't worked. What are my options now?

I have recently had mega problems with my Canon IP7250. I ended up running very hot water through the nozzles both sides. Left to dry and inserted new cartridges.
