Cannon Pro 4000 One color on printhead keeps clogging

I have a Cannon Pro 4000 that the cyan on the nozzle checks continues to have missing sections, the grey occasionally has spots missing but comes back after a cleaning. The cyan will look good after a cleaning but when I print there is banding and the color is not correct. If I do another nozzle check it shows missing sections in the cyan. I have gone into the service mode and printed nozzle checks also. I have done all three cleaning modes also.

Hello. 

If there is no improvement to the gray after multiple cleanings have been performed, service may be required.  Please contact our phone support group at 1-800-423-2366 for additional assistance with this matter.
