2) Do the Head Cleaning.
If the head cleaning doesn’t work then only do Power Cleaning.

In my case the head cleaning, didn’t solve the color printing problem.
3) Power Cleaning
Choose the Power Cleaning. Epson advises to do it once in 12 hours as it consumes much ink. In my case, it used 5-10% of my black ink.



The Nice Color Printing
After I did the Power Cleaning, now my Epson prints the color correctly.
