Pro 10 issue, no CO flow

It looks like you repeat posted your original nozzle check. Did you try The Hat's recommendation of Cyan or Magenta in a CO cartridge?

Yes sir I did, I put some Magenta in,

Ouch!

If your prints look good to you despite no CO then do you need a new print head?

Yes he did, and had his nozzle check looked like this

then he wouldn’t need a new print head..

@Slagathor, the question remains why you had repeated problems with the CO channel, which is usually trouble free. If it were some cheap stuff of dubious quality we could blame that specific brand, but PC inks are among the best, if not the best, non OEM inks available for the Pro-10.
It s a pity that you didn't notice when the problem began. It's important to keep a constant watch on the condition of the nozzles. That's why every time I use the printer I end or start with a nozzle test.

I agree, the only inks used have been PC and stock Canon, PC has been stellar in both my printers....
I do a nozzle check before the prints, and like I said I would usually have to run a clean to get the CO flowing, this time she sat longer then I would have liked between prints and it wouldnt go this time....

Ouch!

Agreed, I will hold off on the new head till a later time...heh
