Hello,
I just replaced the CO ink cartridge on my Pro 10 and ran a print test. On the two prints made I've noticed patching on the CO sample. Can someone suggest what might be causing this and how to resolve it? I am using Canon Ink.
I have attached a photo of the print test. I have increased the exposure and contrast so that it is more obvious. Ignore the shadowed area in the lower left. It is the CO sample I am asking about.
Thanks.
