Didn't filled all Ink colors at the first time

Hello, I just bought a new Epson l310 printer.

in installation program i was asked if all of the ink tubes filled, i clicked yes, but actually i filled just the black color, the printer started to load the ink, it took 20 minutes and all was good with the black color, but when i filled the other colors, i couldn't do the same ink load like in the begining, and now i can't print with colors, what should i do?
