What Ink Does the HP Latex 335 Use?
Last Updated:Correction (October 2026): an earlier version of this guide said the HP Latex 335 uses four HP 831 printheads. It uses six: two Cyan/Black, two Yellow/Magenta, one Light Cyan/Light Magenta and one Optimizer.
Quick answer: The HP Latex 335 uses seven HP 831 775 ml latex cartridges — Black, Cyan, Magenta, Yellow, Light Cyan and Light Magenta inks plus the HP 831 Latex Optimizer. The same cartridges fit the HP Latex 330. Castle Ink carries all seven remanufactured: HP 831 Black (CZ682A), HP 831 Cyan (CZ683A), HP 831 Magenta (CZ684A), HP 831 Yellow (CZ685A), HP 831 Light Cyan (CZ686A), HP 831 Light Magenta (CZ687A) and the HP 831 Latex Optimizer (CZ706A).

| Pillar (weight) | Score | What it is based on |
|---|---|---|
| Owner ratings (28%) | — | No retailer rating with enough reviews to use. |
| Expert reviews (18%) | — | No published numeric expert score we could verify. |
| Cost per page (24%) | — | Not scored: HP rates 831 latex ink by volume (775 ml), not page yield, so we cannot calculate an honest cost per page. |
| Reliability (13%) | 88 | Most-reported problems: recurring printhead error on a head slot that persists after swapping heads; print artifacts caused by intermittent printhead data errors that come back hours after a power cycle |
| Features (12%) | 44 | Ethernet. No document feeder, no auto two-sided printing, no fax, no touchscreen. |

Limited data: We could not find enough owner ratings or published expert scores for this printer, so those weights are spread across the other pillars.
Discontinued. HP ended the Latex 300 series in October 2024; a UK HP reseller names the 64-inch Latex 630 as the closest replacement. HP 831 ink is still sold.

HP Latex 335 Ink Cartridges at a Glance
| Cartridge (Castle Ink link) | Part No. | Size |
|---|---|---|
| HP 831 Black | CZ682A | 775 ml |
| HP 831 Cyan | CZ683A | 775 ml |
| HP 831 Magenta | CZ684A | 775 ml |
| HP 831 Yellow | CZ685A | 775 ml |
| HP 831 Light Cyan | CZ686A | 775 ml |
| HP 831 Light Magenta | CZ687A | 775 ml |
| HP 831 Latex Optimizer | CZ706A | 775 ml |
Every one of the seven slots must hold a cartridge for the printer to run. The Latex Optimizer is not optional — it is a clear fluid that fixes the colored inks to the media surface, so prints come out sharp on vinyl, banner and other non-porous materials.
The Latex 335 was HP's 64-inch mid-range latex printer for signs, banners, vehicle graphics and wall coverings. HP discontinued the Latex 300 series in October 2024 and replaced it with the Latex 630, 700 and 800 range. The 335 uses the same ink as the Latex 330 and the Latex 365.
HP 831 775 ml cartridges fit the whole HP Latex 300 series — the Latex 310, 315, 330, 335, 360 and 365 — plus the Latex 560, Latex 370 and Latex 570. See our HP Latex 315 and HP Latex 365 guides if you run more than one. The larger Latex 370 and Latex 570 can also run HP 871 3-liter cartridges, but they accept these same HP 831 775 ml cartridges too.
Other HP 831 Supplies
The cartridges are only part of the system. The HP Latex 335 also has six HP 831 printheads installed: two Cyan/Black (CZ677A), two Yellow/Magenta (CZ678A), one Light Cyan/Light Magenta (CZ679A) and one Optimizer (CZ680A). It also takes an HP 831 maintenance cartridge (CZ681A). These are long-life parts you replace far less often than ink.
How to Replace Ink in the HP Latex 335
- Wait for the front panel to report an empty cartridge, or open the ink menu and choose to replace one.
- Open the ink cartridge drawer or cover for the color you are replacing.
- Pull the empty cartridge straight out.
- Shake the new cartridge gently a few times before installing it — ink settles while a cartridge sits on the shelf.
- Push the new cartridge into the slot that matches its color label until it locks, then close the cover.
- Check the front panel to confirm the cartridge is recognized before you start the next job.
Troubleshooting Tips
Cartridge not recognized: Reseat the cartridge firmly and check it is in the slot that matches its color label. HP 831 ink is region-coded, and CZ682A to CZ687A are the Americas part numbers, so a cartridge bought for another region may be refused.
Prints smear or stay tacky: Check the Optimizer cartridge first, then confirm the curing temperature and media preset match the material. Latex ink needs the Optimizer and correct curing to set properly.
Banding or missing colors: Run the printhead cleaning and alignment routines from the front panel. If a color is still missing, check the matching HP 831 printhead and the maintenance cartridge status.
What Latex 335 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.
Is the Latex 335 still sold new, and what replaced it?
No. HP discontinued the Latex 300 series in October 2024. A UK HP reseller names the 64-inch HP Latex 630 as the closest equivalent.
Do prints need time to dry before I laminate them?
No. HP says Latex 335 prints come off the printer dry and ready to cut or laminate right away.
What speed should I expect for indoor work?
About 13 m²/hr in the 8-pass indoor quality mode. The 50 m²/hr figure is the 2-pass billboard mode.
A printhead error keeps coming back on the same slot, even after I swap heads. What is wrong?
In an HP Latex community thread, an error that followed the slot rather than the head was traced to a damaged trailing data cable between the electronics board and the printheads. That is a service repair, not a printhead or ink problem.
Latex 335 quirks worth knowing
- HP doubles up on the busiest colors: the 335 has two Cyan/Black heads and two Yellow/Magenta heads, but only one Light Cyan/Light Magenta head and one Optimizer head.
- HP 831 ink is region-coded. CZ682A to CZ687A are the Americas part numbers, so cartridges bought for another region may not be accepted.
- HP also sells 831C 775 ml cartridges under different part numbers (for example CZ696A magenta), so don't be surprised to see two part numbers for the same color.
- Warm-up takes under a minute and a half, and print modes run from 2-pass billboard (50 m²/hr) to 20-pass high-color textile (5 m²/hr).
Frequently Asked Questions
Does the HP Latex 335 use HP 831 or HP 871?
HP 831 775 ml cartridges. HP 871 3-liter cartridges are an extra option only on the Latex 370 and 570, which also accept HP 831.
Is the Latex 335 ink the same as the Latex 330?
Yes. Both take the same seven HP 831 775 ml cartridges.
Can I print without the Latex Optimizer?
No. All seven cartridges, including the Optimizer, must be installed.
Do the Latex 310, 315, 330, 335, 360 and 365 share ink?
Yes. They all take the same HP 831 775 ml cartridges.
Does using remanufactured cartridges void my warranty?
No. Under the U.S. Magnuson-Moss Warranty Act, a manufacturer cannot void your printer warranty only because you used third-party cartridges. Damage proven to be caused by a specific cartridge would not be covered, but the rest of the warranty still applies. Service contracts (HP Care Packs) can carry their own terms, so check yours.
