Hi tenkros
Sorry about that. The title was Officejet 6600. You have the Officejet 6000 model.
I have included this document to go through the steps for colors not printing for the Officejet 6000. How to check the preferences, ink levels, print a diagnostics report to check for defects, make sure the cartridges are properly vented, cleaning and aligning the printheads.
Let me know if that helps.
