Canon ipF8000 won’t color match blue

I use a Mac so I hope somebody out there does also. I recently had to
have the printer repaired because it would no longer pump ink to the
nozzles. the part was replaced and everything works fine. I’ve done a test
pattern print and all colors and lines are intact. When I send an image to
the printer, every color is correct except the blue–deep ultramarine and
royal blues print turquoise. This is the case both when printing both
from the photoshop plug-in or from the printer driver in os 10.4. Any
thoughts?
