How to pump ink in epson l3100?

Question

Epson

Hello
After the purchase, at the initial connection of the printer, only black ink was filled, they were pumped and the printer prints. A few weeks after that, I filled in the color ones, but the printer no longer wants to pump ink, I do it according to the instructions, but the drop indicator does not light up, although it should. It is clear that they had to be filled immediately, because. there would be no such problem, but I would like to know how to make the printer still be able to pump ink and start printing in color?
