Quick answer: the HP OfficeJet Pro 6230 uses HP 934 ink: HP 934 black and HP 935 cyan, magenta and yellow, or the high-yield 934XL and 935XL. Four individual pigment cartridges.
The mistake to avoid is HP 932 and 933. Both families are still on sale, the numbers sit right next to each other, and nothing at checkout will warn you. HP 932/933 fits the OfficeJet 6100, 6600, 6700, 7110, 7510 and 7610. HP 934/935 fits the OfficeJet 6812, 6815, 6820 and OfficeJet Pro 6230, 6830 and 6835. They do not interchange.

Discontinued. HP no longer sells the OfficeJet Pro 6230, and we haven't found a named successor. Its HP 934/935 cartridges are shared with the OfficeJet 6812, 6815 and 6820 and OfficeJet Pro 6830 and 6835.

Dynamic Security, and the fix HP publishes
The OfficeJet Pro 6230 appears on HP's own published list of printers affected by Dynamic Security, the feature that blocks cartridges with a non-HP chip and shows a "Cartridge Problem" error.
It also appears on the list of printers for which HP publishes a firmware update that removes Dynamic Security. That update exists only for the models on that list, and this is one of them. Three things have to be true for it to apply: your printer is on HP's list, you are using an aftermarket supply with a non-HP chip, and you are getting a cartridge error.
That is a genuinely better position than owners of HP's newer OfficeJet 8010 and 8020 machines, where no removal update exists. Our guide to firmware updates and third-party ink covers how to handle these updates generally.
About the HP OfficeJet Pro 6230
This one surprises people: the 6230 is print only. No scanner, no copier, no fax. It is a compact network printer built to sit quietly and produce documents, and it has a button-and-LED control panel rather than a screen.
Speeds are 18 ISO ppm black and 10 ppm color, with automatic duplex printing as standard, a 225-sheet input tray, USB, Ethernet and 802.11b/g/n Wi-Fi. It is discontinued, but it shares its ink with the OfficeJet 6812, 6815, 6820 and OfficeJet Pro 6830 and 6835, so supply is not a problem.
Common problems on this model
"Problem with the printhead", error 0xc19a0020 or 0xc19a0003
The dominant failure on this family. The key fact is that the printhead is a separate part from the cartridges here, so a printhead error is not a cartridge fault. Remove the printhead, clean the contacts on both it and the carriage with a lint-free cloth and distilled water, dry fully, reseat, then unplug at the wall for 60 seconds. If the error keeps coming back, that points to the printhead itself. Owners on HP's forum report that power-cycling and new cartridges often don't clear it.
"Cartridge problem" with third-party ink
Usually Dynamic Security rather than a defective cartridge. Reseat first. Remanufactured cartridges that keep the original HP chip are the safer choice; for cartridges with a third-party chip, HP's removal firmware above is the documented route.
Black or color not printing
Run one printhead cleaning, print a nozzle check, and only then consider a second. Each cleaning consumes ink and a third rarely fixes what the second did not. See faded or streaky prints.
No screen, so errors are hard to read
With only lights and buttons, this printer signals faults through blink patterns. Install HP Smart or the full driver package on a connected computer — the software translates the light codes into plain messages, which saves a great deal of guesswork on this model specifically.
What OfficeJet Pro 6230 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.
Where do I get HP's firmware that removes Dynamic Security?
On the OfficeJet Pro 6230's Software and Drivers page on HP's support site. HP published it for a short list of older models, and the 6230 is one of them.
My fairly new 6230 blinks a printhead error and new cartridges don't help. What now?
Owners on HP's forum report that power-cycling and fresh cartridges often don't clear it. HP replaced affected printers under warranty, in some cases past two years old.
Will your remanufactured 934XL and 935XL work in it?
They keep the original HP chip, so they are the safer choice on a Dynamic Security printer. Cartridges with a third-party chip are the ones that trigger the "Cartridge Problem" error.
Does HP's 2025 lawsuit settlement change anything for my printer?
HP settled a class action over Dynamic Security in 2025, with no payout and no admission of wrongdoing. It agreed to keep disclosing Dynamic Security and to keep letting owners choose whether to install firmware updates that include it.
OfficeJet Pro 6230 quirks worth knowing
- HP's Dynamic Security removal firmware covers only a short list: the OfficeJet Pro 6230, OfficeJet 6810/6820, OfficeJet Pro 6830 and 8610–8660, and the OfficeJet Pro X451, X476, X551 and X576. Later models such as the OfficeJet Pro 6970, 7740, 8210 and 8700 qualify only if they were made before December 1, 2016.
- It is print only, yet it has Ethernet as well as Wi-Fi and USB, plus automatic two-sided printing.
- With no screen, every fault shows as a blink pattern. HP Smart or HP's full driver turns those patterns into readable messages.
