One thing I'd try first is to print a self-test page. If you print a self-test page and the colors appear normal, you can rule out the iMac as the source of the problem.
The instructions for printing a self-test page are similar to the c7280 shown in the following video.

Either the ink you are using is not going to give the color you want, or you have print heads that are blocked.

one of the cartridges is dead and must be changed. buy new one and the problem will be solved.

Generally if both the (red) alarm LED and the (yellow) data LED are both blinking, it is an indication that the tone cartridge needs to be replaced. You should be close to out of cartridge.

The yellow-print-cartridge
light is blinking, and the
printer stops printing.

The print cartridge is
empty or missing.

The printer cannot
detect the print
cartridge correctly.
1. Reinsert or replace the print cartridge.
2. If the print-cartridge light is still blinking but the
Attention light is not on, turn the printer off and
then back on.
3. If the problem persists, repeat the above steps
with yellow print cartridges until the error is
resolved.
4. If the problem persists, replace the printcartridge
E-label reader, which is located on the
pressure assembly of the print-cartridge
carousel.

The photo cartridge replaces the black cartridge. It is used along with the color cartridge to provide better photo's.

The photo cartridge contains photo black, light cyan and light magenta while the color cartridge provides cyan, magenta and yellow. Both photo and color cartridges need to be installed and working for proper photo printing.

Maybe a corrupt software driver, try updated software from the HP web site. Also it could be the electrical connections to the printer cartridges. Remove the cartridges & clean the gold or silver contacts with a pencil eraser. Be gentle & don't touch the contacts with you fingers, as it leaves an oil film & causes contact problems. Rgds,
