Will not print in color Black and grey only. HELP!

HI Thank you for your help I was desperate and called Epson. The ink I put in was new, so the tech had me go to maintenance #4 Ink Cartridge Replacement - to make sure the plastic cover over the ink was removed and the ink cartridge was installed correctly- , then #1 Nozzle check then #2 Head cleaning. I was told I may have to do the Nozzle check 3 times until the paper came out after doing a print check came out with solid lines of each colour with no spaces in between. Twice did it for me.
