Epson India — epson l1300 printer

Hi, i hv bought epson l1300 a3 printer in april 2016 but installed it in march 2017. Print quality was good in the start, but it was not in constant use, i used to take prints occasionally. Nw the print quality is very poor, i did whole cleaning process in which it doesn't show yellow colour in the test prints. I don't understand wat has happened to it. Plz help me asap.

Thnx
Wasima
