canon 9500 pro problems- help please

I've had the printer fo quiet a while, and loved it...printed perfectly BUT yesterday I went to print and oh dear...the colours are all wrong.

I think I must have upset a setting in Photoshop or something but Not sure what LOL.

Could any one please give an idea of where to start?
Very grateful for any ideas of what I've done....and now I'm not sure where to look LOL

Thanks

Please guys...no one out there that can help??

Dawn,

Before you start changing things you might regret, have you done a nozzle check?

My trouble is I panic when things like that happen, and start pressing buttons I should stay away from.

If the nozzle check is OK, what colour changes are you seeing?

well everything has a greenish or pinkish tint which is making me really sad LOL...

Check nozzles and ink levels.
What settings do you use to print (both in PS & printer driver)? Photoshop or printer manages colors?

Yes, a nozzle check is certainly a good idea. Also have this printer, and sometimes it sees little use for a few weeks. I have had ink cartridges dry out. A new cartridge for the color which fails the nozzle check, and all is good again!

well, I did have PS managing the colours...but I may have accidentally upset the settings (although I will do a nozzle check) now I'm not sure where the settings should be .....
any help greatly appreciated.

Have a look in the link from my sig, there's a link about color managed printing.

dawnrogers,

I had a similar problem a while back. Colors were all off without a warning. None of the ink tanks reported empty, or even near empty.
I tried the option where you can print patches of individual colors to see if a particular nozzle is blocked. The yellow color patch didn't print at all. I did a nozzle clean, but no effect. I then manually checked the yellow ink cartridge and discovered that it was actually empty.

That is when it struck me that the cartridges' chip had gone bad, and so it wasn't reporting an empty state back to the software that monitors ink levels. I replaced the yellow tank and voila - great prints again!
