Epson R 300 Printer

The R300 has been a great printer and produced some seriously good photo's however it has now posted a message that a Service is due and some parts are at the end of life and I should look in the handbook for details. The handbook says nothing about servicing and I feel that there is some electrical component in the printer that is keeping count on the number of prints. I am sure there must be some way of resetting the printer through my PC. Is there some way of doing this as my replacement printer is nowhere near as good as the R300?
