Epson printer problem?

Hi guys! I got a problem with my epson printer. I have epson 88 ink for all colours( black, magenta , yellow and blue). I was running out of black ink. So, I bought a Epson 69 Black ink. Can I use Epson 69 black ink with other colours(Black, Magenta, Yellow and BLue). BTW the other colours are Epson 88 inks. I mean is Eson 69 Black compatible with other colours which are 88?
