When I change paper sizes on my Canon 9000 mark II, I have been getting odd colors on some size paper settings.Paper type and other settings are the same.I did try to download new driver when this started to occur. However, I deleted the new driver and reinstalled the old print driver. The problem has not gone away.

The printer only does what it is told.  Barring a malfunction, that is.  So, I would look else where.  Your photo editor?

Thanks for your reply. I had someone take a look at the printer. It is a hardware issue.
