Hello, Ko -
I hope I am correct in thinking your question refers to an Epson Stylus Photo RX580 printer.
I am not quite sure what you mean by "reset service life."
Did you, perhaps, receive a message about the printer being at the end of its service life? If so, I believe the information here (an Epson United States web page) may explain that message:

If you did receive an Epson maintenance message about the printer being at the end of its service life, that means it is time to choose and purchase a new printer.
My personal experience with Epson printers (I have owned a series of Epson printers over 20 years) is that they seem to have a maximum service life of about 6-7 years.
Best wishes.
