HP DesignJet T870 Ink & Paper

Frequently asked questions

Which ink cartridges fit the HP DesignJet T870?

The HP DesignJet T870 takes HP 738 130-ml Black DesignJet Ink Cartridge, HP 738 130-ml Cyan DesignJet Ink Cartridge, HP 738 130-ml Magenta DesignJet Ink Cartridge, HP 738 130-ml Yellow DesignJet Ink Cartridge, HP 738 300-ml Black DesignJet Ink Cartridge, HP 738 300-ml Cyan DesignJet Ink Cartridge, HP 738 300-ml Magenta DesignJet Ink Cartridge and HP 738 300-ml Yellow DesignJet Ink Cartridge. Every cartridge listed on this page comes from the manufacturer's supply listing for this model.

What roll widths and core sizes does the HP DesignJet T870 take?

It takes rolls up to 24 in wide on 3 in cores. The spindle holds a finished roll up to 130 mm in diameter, which is what separates a 150 ft roll from a 300 ft roll of the same paper. It also takes cut sheets.

Does the HP DesignJet T870 use dye or pigment ink?

The HP DesignJet T870 runs aqueous pigment ink. Pigment ink sits on the surface as solid particles, so prints are more water- and fade-resistant than dye — the reason it is the standard for technical and fine-art output.

What paper can I use in the HP DesignJet T870?

We hold 44 paper and media products verified against this machine, 36 of them at the recommended tier, where compatibility is resolved from the printer's published media handling — roll width, core size, the roll diameter the spindle holds and the coating's rating for this machine's ink. The rest come from the supply list the manufacturer publishes for this machine. Either way a roll only appears here if a source says it fits.

How do you know these supplies fit the HP DesignJet T870?

Nothing on this page is matched by model name alone: the cartridges and printheads come from the manufacturer's own published supply listing for this exact model and each paper and media roll is checked against the printer's published media handling — roll width, core size, the roll diameter the spindle holds and the coating's rating for this machine's ink. If a part is not listed here, it has not been verified for this machine — call 980-536-0080 and we will check it before you order.
