not printing in color

[reeves ray chibamba]

I have a Hp cp5225 printer printing only in black and white on the machine if I command a demo page or a supply page no color is coming out I tried to install color cartridges it showed that genuine Hp cartridges installed 100% but still didn't print in color after some time it showed 0% for all 3 color cartridges even when the cartridges were at 100 % it didn't print color on demo and supply pages

What could be the problem
