Canon iP3000 nozzle test with missing bands

I have an iP3000 that started printing photos in black and yellow only.

Nozzle check shows no clogged nozzles, rather some color bands in the test pattern are completely missing. The five color bands appear as follows:

-6C (dark cyan) - color band is missing, label and gray blocks are yellow
-6C (light cyan) - color band is OK, label is yellow but gray blocks OK
-6M (dark magenta) - color band is missing, label and gray blocks are yellow
-6M (light magenta) - color band is OK, label is yellow but gray blocks OK
-6Y (yellow) - color band is OK, label and gray blocks are yellow

All carts contain ample ink. Print head has been removed and reseated. Seem to recall re-installing the driver - but not sure.

Is this a cabling or logic issue, or what? Is it likely that the problem is NOT the print head and assembly? (I have the option to mail order a used printer with a bad print head but otherwise good.)
^^ Replaced the image in the post above with one that more accurately shows the situation. The spottiness is an artifact of the scan - the colored bands (when present) are solid.
