Ink specs for HP OJ Pro 8500?

[jlynch62]

Which ink is the HP OJ Pro 8500 designed for?  Dye base or Pigment base, all 4 colors or a mixture?

HI,

As far as i can find this printer uses pigment based inkt.

I'm confused!  The specs for the OJ Pro 8500 - 909g state as follows:

• Black print resolution : Up to 1200 dpi with pigmented black ink

• Color print resolution : HP enhanced photo quality with Vivera inks

Arn't Vivera Inks Dye based?  And if so, I am assuming that the Black HP #940 cartridges have pigmented ink and the Color #940 cartridges have Dye based ink.  Is this true or do all #940 cartridges contain the same ink type? .

I guess my primary question is "Can we use dye based ink for all colors including black on the OJ Pro 8500?

I have found that all HP #940 cartridges, Black and Color are pigmented ink.
