Cannon MP780 has bright green saturation - help

[mipspc]

I have had my printer for 8 months and very pleased with it. A week ago all my color prints have a bright greenish hue to them. I have used up a lot ink going thru many, many cleaning cycles with no noticiable difference. I had this problem once before but a couple of deep cleaning cycles took care of it, but not now. I don't think more green is being added to the print, just that less of some other color is the problem. Any ideas???

To mipspc,

Step one is always a nozzle check---but odds are your yellowor magenta will be hokie or missing in action. Then its into troubleshooting---is it a bad cartridge, a clogged printhead, or electrical problems on the printhead?

But if one or two deep cleanings don't help, more is not better. But if its only eight months old it should be under warranty---so do things under Canon tech support supervision. But if your printer is sick, making it print without a supply of ink to affected nozzles can damage the printhead.

So do one nozzle check and call Canon tech support.
