Help, any epson 3000 users or someone who knows alot about printers

[joe_paulo1]

hi, thanks for taking the time to look, i have an epson 3000 colour printer that i have

never used (was given it free as the person didnt want it anymore) i have tried

printing on the printer and it prints but no black or yellow appear in the prints, the

black cartridge is almost full and the yellow still has a bit left (both cartriges are 3

years out of date) i have treid cleaning the heads numerous times. the printer i belive

was not used for about 2 years is there an easy fix?, is this a commen problem when

a printer is not used for a long time?, I am asking as i plan to sell it on ebay and want

to check that is in full working order so that i can state so in the listing, basicly what

do i do to get the ink flowing (if its possible). thanks in advance
