    Canon Pro-10S, Cyan is printing in my Chroma Optimizer (CO) on the nozzle check test pattern. Can someone explain what the problem is?

    I did as Websnail suggested and looked to see if there were any traces of C in the CO when dabbing the print head into a damp kitchen paper. I could not see any C in the CO. Which should mean that there is no internal leakage in the printhead. After soaking the print head in cleaner, then...

    Canon Pro-10S, Cyan is printing in my Chroma Optimizer (CO) on the nozzle check test pattern. Can someone explain what the problem is?

    Thanks, guys, My feelings are that there may be cross-contamination between the cyan and the CO. I did a partial clean of the print head by flushing it with de-min water then fitted new C and CO cartridges. I performed a nozzle clean cycle and a test print. The results were much better...

    Canon Pro-10S Group 2 Colors do not Print after the Printer was Left Idol for a Year- Help!

    I have been on a work contract away from home for just over a year. The printer was working as it should when I left but now none of the group 2 colors print on the test sheet. Could there be a clog in the print head affecting all of group 2 colors? After deep cleaning group 1 colors print...
