Canon i960 Inkjet printing too much blue

[Inkkianthus]

The Canon inkjet i960 is printing photos of stones taken at night in a partially lit garden is turning all grays and slate grays to blue and aqua. I've deep-cleaned the printheads twice. A few weeks ago the same photos printed more accurately. Advice on correcting this problem would be welcome.
Also, I can't find my users manual, and wonder if there is a way to get it online.

Here is where you can download the user manual.

What does your nozzle check look like?

You should not print anything except nozzle checks until you get this resolved or else you run the risk of permanently damaging your print head.

I second looking at the nozzle checks, if they print evenly and consistently then I'd be looking at your ink. Did you recently start refilling? If so you'll need to profile the printer to get accurate color.
