The printer colors are suddenly off. I have new HP brand cartridges just installed in September with plenty of life left. I took them each out and gave them a shake before putting them back. I have a feeling that one of them is malfunctioning, but I am not sure how to determine which one it is.
I have tried printing from multiple devices and multiple sources so I am sure the problem is with the printer itself.
The easiest way to test is to create a page of each of the primary colors Cyan, Magenta and Yellow and see which page looks bad and that is likely the culprit.
