Question about Canon i9100 InkJet Photo Printer
It may not be the case, but the nozzles are controlled by electronic signals and the common line for red may be defective.
If you cannot see any traces of red ink on the printhead surface and blotting (not WIPING) it with a hard paper towel produces little or no red on the paper, it is likely not getting any input from the control circuitry any more.
You can try GENTLY cleaning the electrical contacts (not the printing surface itself) on both the printhead and carriage with a cleaned pencil eraser or a Q-tip (look for lost fibers though)dampened with alcohol.
Unfortunately, if you can't restore it, the labor cost of having it repaired will probably be prohibitive.
