What Ink Does the HP OfficeJet Pro 6830 Use?
Last Updated:Quick answer: the HP OfficeJet Pro 6830 uses HP 934 black and HP 935 cyan, magenta and yellow, or the high-yield 934XL and 935XL. Four individual pigment cartridges.
The trap here is numeric. HP 932 and 933 do not fit this printer, and they are still sold, so a shopper can pick up the wrong box and it will not look like a mistake at checkout. HP 932/933 belongs to the OfficeJet 6100, 6600, 6700, 7110, 7510 and 7610. HP 934/935 belongs to the OfficeJet 6812, 6815, 6820 and OfficeJet Pro 6230, 6830 and 6835. There is no compatibility between the two families.

The Dynamic Security question, and the fix HP publishes
This is the most useful thing on this page. The OfficeJet Pro 6830 is on HP's own published list of printers affected by Dynamic Security — the feature that blocks cartridges using a non-HP chip and produces a "Cartridge Problem" error.
The good news is that HP also publishes a firmware update that removes the Dynamic Security feature, and it is available specifically for the printers on that list, this one included. HP published it in January 2017. Three conditions have to hold: your printer is on HP's list, you are using an aftermarket supply with a non-HP chip, and you are seeing a cartridge error.
Remanufactured cartridges that keep the original HP chip, like ours, aren't what dynamic security targets, so they avoid the question entirely. Our guide to firmware updates and third-party ink explains what these updates change and how to stay in control of them.
About the HP OfficeJet Pro 6830
A small-office all-in-one: print, scan, copy and fax at 18 ISO ppm black and 10 ppm color, with automatic duplex printing and a 35-sheet ADF. Input is 225 sheets, the display is a 2.65-inch color touchscreen, and connectivity covers USB, Ethernet, 802.11b/g/n Wi-Fi and a fax line. HP rates it for 200 to 800 pages a month.
HP has discontinued it, and its store now points to the OfficeJet Pro 9015e, which uses different cartridges. Ink for the 6830 remains widely available and the machine shares its cartridges with the OfficeJet 6812, 6815, 6820 and OfficeJet Pro 6230 and 6835.
Common problems on this model
"Problem with the printhead", error 0xc19a0020 or 0xc19a0003
By far the dominant failure on this family, and the printhead on the 6830 is built into the printer, so it isn't something you can swap. HP's agents suggest a hard reset first: with the printer on, unplug the power cord, hold the power button for 15 seconds, then plug it straight into a wall outlet rather than a surge protector. If the error comes back, HP treats it as a hardware fault and the next step is HP service.
"Cartridge problem" with third-party ink
With a non-HP chip, this is usually dynamic security rather than a faulty cartridge. Reseat first, then see HP's removal firmware described above. Remanufactured cartridges that keep the original HP chip don't trigger it.
Black or color not printing
Run a printhead cleaning from the touchscreen, then print a nozzle check before running a second cycle. Two cleanings is the sensible limit — each one uses ink. See faded or streaky prints.
"The print carriage cannot move"
Open the cartridge door, remove any torn paper from the carriage path, and check that no cartridge is sitting proud of its slot. Power-cycle afterwards so the printer re-runs its startup calibration. Our paper jam guide covers the rest.
What OfficeJet Pro 6830 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.
My 6830 rejects third-party cartridges with a "Cartridge Problem" message. Is there a fix?
The 6830 is on HP's dynamic security list, and HP published optional firmware that removes the feature for listed printers that show a cartridge error with a non-HP chip. Remanufactured cartridges that keep the original HP chip, like ours, aren't what dynamic security targets.
Can I replace the printhead myself?
No. An HP employee told a 6830 owner the printhead is built into the printer and isn't user-replaceable. A printhead error that won't clear out of warranty usually means a hardware fault.
Will it connect to 5 GHz Wi-Fi?
No. HP lists 802.11b/g/n on 2.4 GHz only. If setup fails on a dual-band router, use the 2.4 GHz network or the 10/100 Ethernet port.
How much printing is it built for?
HP recommends 200 to 800 pages a month, with a maximum duty cycle of 15,000 pages.
Will my spare 934/935 cartridges fit HP's newer model?
No. HP's store points 6830 shoppers to the OfficeJet Pro 9015e, which takes different cartridges. Spare 934/935 cartridges fit the OfficeJet 6812, 6815, 6820 and OfficeJet Pro 6230 and 6835.
OfficeJet Pro 6830 quirks worth knowing
- HP measured the 934XL's ~1,000-page yield in the OfficeJet Pro 6830 itself, so the rating is a fair guide on this printer.
- HP's dynamic-security removal firmware covers only a short list: the OfficeJet Pro 6230, OfficeJet 6810/6820 and OfficeJet Pro 6830 (HP 934/935), the OfficeJet Pro 8600 series (HP 950/951) and OfficeJet Pro X models (HP 970/971).
- We also sell a remanufactured 934XL black in MICR ink for printing checks, and it fits the 6830.
- It has a real fax modem with 100 pages of fax memory and 99 speed dials, plus a 35-sheet document feeder.
FAQ
What ink does the HP OfficeJet Pro 6830 use?
HP 934 black with HP 935 cyan, magenta and yellow, or the high-yield 934XL and 935XL.
Does the OfficeJet Pro 6830 use HP 932 or 933?
No. Those fit the OfficeJet 6100, 6600, 6700, 7110, 7510 and 7610. The numbers are adjacent but the cartridges are not interchangeable.
Why is the black cartridge numbered 934 and the colors 935?
That is just how HP split the family — one number for the black, one for the three colors. They are designed to be used together.
Is there a 934XXL or 935XXL?
No. XL is the largest size in this family.
Does the OfficeJet Pro 6230 use the same ink?
Yes — the same 934 and 935 family. The 6230 is the print-only version with no scanner.
