When you refer to "red" do you mean red or are you referring to magenta
(a sort of hot pinky-purple color). Your printer uses a somewhat
unusual inkset for inkjet printers, in that it has Cyan, Photo Cyan,
Magenta, Photo Magenta, Yellow, black plus red and green. Red printing
can be made up of yellow and magenta together, or just the red ink, and
in the case you refer it I am not sure what is supposed to be visible
where that red area you refer to is. It could be pure red ink, or it
could be a mix of the magenta and yellow. Typically if a red image area
is printing yellow, it means the magenta part of the head or ink is not
running. But since your printer has a red cartridge as well, I'm
somewhat at a loss as to what may be happening there.
