HP 712 3-pack 29-ml Yellow DesignJet Ink Cartridge (3ED79A)

Which printers take this part

These cartridges are listed for the HP DesignJet T650, 24-in or 36-in. If your machine is a different DesignJet, its supply is a different HP part number — find your machine on the genuine HP parts page.

Yellow, bought ahead

Yellow is part of every full-color mix, so it is consumed at a rate comparable to the other process colors — which is what makes it worth holding in depth rather than one tank at a time.

What the carton holds

Three tanks of 29 ml each, 87 ml of yellow in one box. The single-tank equivalent is 3ED69A. Both pages show their current price above the Add to Cart button, and that is the figure to compare.

Don’t order this one by mistake

For one tank, order 3ED69A. The three-carton format exists for the color inks only — 3ED77A cyan, 3ED78A magenta, and this yellow box. There is no black three-pack in the 712 range, so black is ordered as a single tank: 3ED70A at 38 ml or 3ED71A at 80 ml.

Storage and shelf questions

How should spare tanks be stored?

Cool, dry and sealed, used in the order they arrived — and use each carton before the date printed on its packaging.

How do I tell a 3-pack carton from a single on the shelf?

By the part number on the box: this carton is 3ED79A and holds three tanks, while a single yellow tank is 3ED69A.
