Why does my HP OfficeJet Pro 6978 print a test sheet perfectly, but streaks terribly when I print something in color (particularly anything with blue in it)?  I have cleaned the printer heads both auto and manually and changed the cyan printer cartridge.

You can sometimes get lint stuck under the carriage where the cartridges mount and that can track ink across the page. You will likely need to use a flashlight to see and then use a q-tip to gently remove it.
