What Ink Does the HP DesignJet T630 Use?

Quick answer: the HP DesignJet T630 uses HP 712 ink — four cartridges — plus a separate HP 713 printhead, part 3ED58A. The ink and the printhead have different numbers on this generation, which is the single most common ordering mistake.

The other one to avoid is HP 711. That fits the older DesignJet T120 and T520. The cartridges look similar enough that cross-listing is rampant, and they do not interchange.

HP DesignJet T630 ink at a glance

Large-format ink is priced and sold by volume rather than page yield. HP's guidance for this class is roughly 20 ml per 101 A1 pages, maintenance included. The 80 ml black is the sensible buy on any plotter doing regular drawing work — black is what you actually consume.

If you shop internationally, avoid HP 712B (3ED28A and 3ED29A). It is a separate black sold in Australia, Singapore, Hong Kong, India, Thailand and Malaysia, and it appears in HP's worldwide spec sheets alongside the US parts, which is how US buyers end up with it.

Castle Ink recommendation

We stock the ink, not the 3ED58A printhead — that comes from HP or a large-format parts supplier if yours has genuinely failed.

About the HP DesignJet T630

An entry-level current-generation plotter in 24-inch and 36-inch widths, print only, no scanner. Around 30 seconds per D-size page and roughly 76 D prints an hour, 1 GB of memory, up to 2400 by 1200 dpi, gigabit Ethernet, USB 2.0, dual-band Wi-Fi and Wi-Fi Direct.

The T630 is the slower, lower-cost sibling of the T650 — same ink, same printhead, same media handling. HP now lists the 24-inch as discontinued and points the 36-inch at a newer model, but HP 712 is current and easy to get.

Common problems on this model

Roll feed not detecting paper

The most-reported fault on the T600 series. Reseat the roll tightly on the spindle first — a loose roll is the usual cause, and packing the spindle wings with folded paper is a widely used field fix. Then try a different roll, since transparent or unusual media can defeat the sensor entirely. Then check the paper switch behind the sheet loader for trapped scraps.

Media loads but will not advance

Clean the line sensor lens. Printhead leakage puts ink on the service-station brush, which transfers to the sensor and blinds it. This one looks like a hardware failure and usually is not.

Banding, incomplete images or blurry lines

Run the printhead cleaning routine, then a printhead alignment, then calibrate colour for the specific media loaded. If cleaning will not recover it, 3ED58A is the part.

Paper mismatch and roll jams

Make sure the media type set on the front panel matches what is physically loaded. A mismatch changes both the drying time and the cutter behaviour, and produces jams that look random.

FAQ

What ink does the HP DesignJet T630 use?

HP 712 in black, cyan, magenta and yellow, plus the HP 713 printhead kit 3ED58A.

Is there an HP 712 printhead?

No. The printhead for these machines is the HP 713 (3ED58A). Any listing selling an "HP 712 printhead" is mislabelled.

Does the T630 use HP 711?

No. HP 711 fits the T120 and T520.

Does the T630 take the same ink as the T650?

Yes — identical ink and printhead. The T650 is simply faster.

What is HP 712B?

A regional black cartridge sold outside the US. Not the right part for a US machine.

Does the T630 have a scanner?

No. It is print only. The DesignJet T830 is the multifunction plotter with a scanner, and it uses HP 728, not 712.
