Just changed the color cartridges on my HP 6830. Now green prints yellow. How do I fix?

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. 

Does this happen while copying too?

Let's clean the Printhead:

1. Load plain white paper into the tray.

2. On the printer control panel, swipe the display to scroll to Setup, and then touch the Setup icon .

3. Swipe the display to scroll to Printer Maintenance, and then touch Printer Maintenance.

4. Touch Clean Printhead.

   A test page prints.

5. Examine the test page.

   • If the print quality is unacceptable, touch Clean Again to continue the next level of cleaning. If necessary, repeat these steps for the third cleaning cycle.

     NOTE: 

     If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes before you perform all three levels of cleaning again.

   • If the print quality is acceptable, touch Done.

If the issue persists, please perform the remaining steps from this document:
