Epson C84 printer problem, please help

[ssgohan434]

I have had the printer for about a year and half now and it just started giving problems a month ago. Anyways since that month i havent needed to use the printer much anyway so i havent tried to fix the problem. But now im trying to fix the problem and i cant figure out what it is. The problem is that the printer will do the normal printing process and spit the page out while taking its time like its actually throwing ink on there, but when the paper comes out there are barely any smudges of ink on there. Sometimes none. This problem is mainly with the black ink. The yellow ink prints normally for some reason. The other colors are also barely putting out any ink at all. Its not the ink running out because i just put a brand new black ink cartridge in there and its still doing the same problem, barely/no ink on the paper. What's the problem here? Anyone wanna help me out because i got one cartridge of each color closed here and i dont wanna throw them away because they are not even opened. Someone please help me. :cry:

thnx

EDIT: the Printer is an EPSON C82, not the C84, i mistyped the threads tittle. If any mods see this would they please change the printer in the tittle. thanks
