What Ink Does the HP DesignJet T650 Use?

Quick answer: the HP DesignJet T650 uses HP 712 ink — four cartridges — plus a separate printhead. And here is the detail that catches almost everyone: the printhead is not called 712. It is the HP 713 printhead, part 3ED58A. There is no such thing as an HP 712 printhead.

The other trap is HP 711, which fits the older DesignJet T120 and T520. The cartridges look alike and get cross-listed constantly, but they are not interchangeable.

HP DesignJet T650 ink at a glance

Large-format ink is sold by volume, not page yield. HP's published guidance for this class is roughly 20 ml per 101 A1 pages including maintenance use. Black comes in 38 ml and 80 ml, and on a plotter producing drawings the 80 ml is the one to buy.

One thing to avoid when shopping outside the US: HP 712B (parts 3ED28A and 3ED29A) is a separate regional black sold in Australia, Singapore, Hong Kong, India, Thailand and Malaysia. It turns up in HP's own worldwide spec sheets and confuses US buyers. Stick to 3ED70A and 3ED71A.

About the HP DesignJet T650

A current-generation entry plotter in 24-inch and 36-inch widths, print only, with no scanner. Fast for the class — about 25 to 26 seconds per D-size page and better than 80 D prints an hour — with 1 GB of memory, up to 2400 by 1200 dpi, and connectivity over gigabit Ethernet, USB 2.0, dual-band Wi-Fi and Wi-Fi Direct.

The T650 is still sold new as the HP DesignJet T650 2025 Edition, in 24-inch and 36-inch widths. HP 712 is current, and the T650 shares it with the T210, T230, T250, T630 and the DesignJet Studio.

Common problems on this model

"The printer cannot detect or load the media"

A common complaint on the T600 series. Work through it in this order: reseat the roll tightly on the spindle — a loose roll is the usual culprit, and packing the spindle wings with folded paper is a well-used field fix. Then try a different roll, since transparent and unusual media confuse the sensor. Then inspect the paper switch behind the sheet loader for jammed scraps.

Paper loads but will not feed

Check the line sensor lens. Printhead leakage deposits ink on the service-station brush, which then transfers to the sensor and blinds it. Cleaning that lens resolves a class of feed faults that otherwise looks like a hardware failure.

Banding, line-thickness errors or blurred output

Run the printhead cleaning routine from the front panel, then a printhead alignment, then a colour calibration for the media actually loaded. If cleaning cannot recover it, the 3ED58A printhead is the part to replace. We sell HP 712 ink, not the printhead, so that comes from HP or a large-format parts supplier.

Cutter not cutting cleanly

Check for media debris in the cutter path and confirm the media type in the driver matches what is loaded — the cutter behaves differently on film and heavy stock than on bond.

What DesignJet T650 owners ask

These are the questions that come up most for this printer on retailer Q&A pages, HP's support forum and owner reviews, answered in our words.

Will the T650 accept non-HP cartridges?

HP says this plotter uses dynamic security to block cartridges with non-HP chips, and that firmware updates can block cartridges that worked before. Cartridges built on original HP chips avoid this.

Do the 24-inch and 36-inch T650 take the same supplies?

Yes. HP lists both widths for the same HP 712 cartridges and the same HP 713 printhead kit (3ED58A).

What does a replacement printhead cost?

Adorama listed the HP 713 printhead kit (3ED58A) at $306. It is the expensive part on this plotter, so run the cleaning routine before you decide it has failed.

I replaced an HP 712 cartridge and now get a "Supply System Problem". Is the cartridge bad?

Not necessarily. On the T210, which uses the same supplies, HP Community advice was that if reseating and cleaning the cartridge contacts doesn't clear it, the printhead may be failing. Check the printhead and your warranty status.

Is the T650 still sold new?

Yes. Retailers sell it as the HP DesignJet T650 2025 Edition. Adorama listed the 24-inch bundle at $1,926 in October 2026.

DesignJet T650 quirks worth knowing

• The black is pigment ink with a 12 pl drop; cyan, magenta and yellow are dye inks at 5.5 pl. That is why black linework stays sharp on plain bond.
• HP 712 ink and the 3ED58A printhead also fit the DesignJet Studio (Wood and Steel, 24- and 36-inch), not just the T200 and T600 series.
• Leaking printheads can foul the service-station brush at the far right of the carriage path. The brush then smears ink onto the line sensor, which shows up later as media-detection errors.
• It has 1 GB of memory, twice the 512 MB in the T210, plus an automatic horizontal cutter and an automatic sheet feeder.
