hi all,

I have Brother MFC 210C printer. I havn't using it almost for 2-3 months. Recently I have changed all the cartridges. But the Black cartridge dosn't work..I mean I can't print the text page. All colors are working fine. Since black dosn't work I can't get proper color print out. Also I have refill kit for my erlier printer. Whats the use of flush cleaner liquid & how to use that??
Can any one help me solve this problem??
