Hi veeves,
Please make sure your inks are at least half full and then perform an ink flush with your PIXMA G6020:
1. Turn your PIXMA G6020 on.
2. Please press the wrench and screwdriver button on your G6020 one time.
3. Repeatedly press the right arrow button to select Maintenance and press OK.
4. Press the right arrow button to select Ink Flush and then press the OK button.
5. Choose All Colors and press OK.
6. Check the displayed message and press the OK button.
7. Use the left arrow to select Yes and then press the OK button.
8. Use the left arrow again to select Yes and press OK.
The process will take 6-8 minutes. If it stops sooner, please perform these steps again.
Once complete, repeatedly use the left arrow to select Nozzle check and press OK.
The nozzle check should appear like the example attached below.
If colors still do not print correctly, the color printhead could be clogged.
