HP 776 1-liter Magenta DesignJet Ink Cartridge (1XB07A)

1XB07A is the genuine HP 776 magenta ink cartridge, a 1 liter tank for HP DesignJet Z9+ poster printers — the engine in the PSE Education Print Center Pro 64.

Which printers take this part

Fitment for this part is the Z9+ series. The Z6 shares several color names with this range but none of its part numbers or tank sizes; the 300 ml HP 746 magenta, P2V78A, is the one magenta we list that fits both the Z6 and the Z9+.

What magenta does here

Magenta is one of the primary inks the printer draws on for a broad range of colors including reds, pinks and purples. Chromatic red is a specialty ink that extends the set’s gamut rather than replacing magenta — both stay loaded.

Size and cost per milliliter

Per milliliter, a liter of 776 magenta costs less than P2V78A, the 300 ml HP 746 magenta we also stock for this platform. Every 776 liter cartridge shares that same cost per milliliter, so no one color in the range is cheaper than another. The trade is order value: one liter on a single purchase order instead of three smaller tanks. Volumes and prices for every part we stock are listed in the genuine HP ink category.

Don’t order this by mistake

The number below this one, 1XB06A, is not a color at all — it is the gloss enhancer, and it is the one part in this range supplied at 500 ml rather than a liter. The number above, 1XB08A, is yellow. And the magenta that does cross to a Z6, P2V78A, is a 300 ml HP 746 cartridge rather than a smaller 776 tank — check the range as well as the color.

Questions schools ask about this cartridge

Does chromatic red mean we need less magenta?

No. Chromatic red is a specialty ink that extends the set’s gamut rather than replacing magenta, so both stay loaded and both get used.

We run a Z6 and a Z9+. Can one magenta cover both?

Only the 300 ml HP 746 magenta, P2V78A, crosses both platforms. This liter is listed for the Z9+ series only.
