[INKAPRINTCLT]

I need help with this, I am getting big horizontal lines when printing black in on my Pixma 8720. Nozzle check and cleaning results are perfect but black prints come our bad. What can I Do?

See picture of the problem below.

Thanks!

Hi,

We would need to know what version of Windows or MacOS you are running and what program you are printing from. 
Also, if possible please attach a picture of the nozzle check from your printer to your reply. 

We look forward to hearing from you.
