HP Printer Not Printing Black Ink? Here's What Actually Fixes It

by William Elward Last Updated: September 24, 2026

Your HP printer is producing perfect colour and nothing where the black should be. Or the text is coming out faint, brownish, and washed out. Either way, the instinct is to buy a new black cartridge — and most of the time that is not what fixes it.

The cause is almost never a bad cartridge. It is usually a clogged printhead, a missed alignment, or HP's anti-counterfeit chip throwing a fit. This guide works through the fixes in the order that actually resolves the problem, and tells you where the real decision points are.

Quick Answer

Run the printer's cleaning cycle once, print a test page, then repeat at most twice more. Each cycle burns a meaningful amount of ink and diminishing returns set in fast. If three cycles have not brought black back, wipe the printhead by hand with distilled water rather than running a fourth.

Before any of that, check two things that take ten seconds each: that the orange tape and clip came off a newly fitted cartridge, and that no other cartridge is reading empty — HP will block a plain black text job because the magenta ran out, and it will not always tell you that is why.

Start Here: Which Version of This Problem Do You Have?

What you are seeing	Most likely cause	Go to
Colour is perfect, black is completely missing	Black nozzles clogged after an idle spell	Fix 1, then Fix 2
Black text looks brownish, greenish or grey	Printer is building composite black from colour ink because black is dry	Fix 3
Nothing prints at all and a cartridge warning is showing	Low-ink interlock blocking the whole job	Fix 9
Started the moment you fitted a new cartridge	Tape or clip still on, or dirty contacts	Fix 6, then Fix 4
"Cartridge problem" or "counterfeit cartridge" on screen	Firmware rejecting a third-party cartridge	Compatible and Remanufactured Cartridges
Text prints but looks faint or doubled	Printhead out of alignment	Fix 5
Everything prints in grey, no colour anywhere	Grayscale or draft setting in the driver	Fix 10
You are not sure which cartridge is at fault	Nothing yet — get the data first	Fix 7 — print the diagnostic report

First: Does Your Printer Have a Separate Printhead?

This determines almost everything that follows, and it takes one glance at the cartridge bay to settle.

Architecture	Typical models	What it means for you
Printhead built into the cartridge	DeskJet, ENVY, entry-level all-in-ones — the two-cartridge systems using HP 63, 65, 67, 305 and similar	A new cartridge is a new printhead. Swapping the cartridge genuinely fixes a clog, and an old clogged cartridge is rarely worth rescuing.
Separate printhead in the printer	OfficeJet Pro, PageWide, Smart Tank — the ones with four individual cartridges	A new cartridge will not fix a clog, because the head stays in the printer. Cleaning is the only route, and a genuinely failed head means printer-level repair.

The quick test: two cartridges means an integrated head, four individual cartridges means a separate head.

1. Run the Built-In Printhead Cleaning Cycle

This is the single most common fix. HP inkjets share a printhead between black and colour, or on OfficeJet Pro and PageWide models have a separate black head, and the nozzles dry fast if you go more than a couple of weeks between print jobs.

Run it from the printer's front panel: Setup > Tools > Clean Printhead. On models without a touchscreen, use the HP Smart app, or the printer's own web interface — type the printer's IP address into a browser on the same network.

Run the cleaning cycle once.
Print a test page.
If black is still missing, run a second cycle.
Don't run more than three cycles back-to-back — you'll waste a lot of ink.

On the HP DeskJet 2700 series, black problems often come down to a cartridge running dry sooner than the yield rating suggested rather than a clog at all, so check the level (Fix 3) before you spend three cycles on it.

2. Wipe the Printhead by Hand

If the automatic cleaning did not do it, dried ink is holding the nozzles shut and needs physical help.

Pull the black cartridge out.
Dampen a lint-free cloth or a coffee filter with distilled water — not tap water, which leaves mineral deposits behind.
Gently dab the copper-coloured nozzle plate on the bottom of the cartridge.
You should see black ink transferring onto the cloth. That is the sign it is working.
Reinstall the cartridge and print.

If nothing at all comes off onto the cloth after several dabs, the cartridge is either empty or the nozzles are set hard. For a stubborn one, rest the nozzle plate on a distilled-water-dampened pad for ten to fifteen minutes before dabbing again — the soak dissolves what wiping cannot shift. Blot dry before reinstalling; do not let water reach the electrical contacts.

3. Check That You're Not Out of Black

This one is counterintuitive, which is why it catches people: HP printers will often keep printing colour jobs perfectly while the black cartridge is bone dry. They do it by mixing a composite black out of cyan, magenta and yellow.

The giveaway is the colour of the text. If your black looks brownish or greenish instead of crisp black, you are looking at composite black and the real black cartridge has nothing left in it.

Do not trust the on-screen level alone. Pull the cartridge out and weigh it in your hand — an empty one feels noticeably lighter than a new one. HP's level readings are estimates based on page counts and drop counts, not measurements, and they drift.

Replacements are in our HP ink cartridge range.

4. Reseat the Cartridge and Clean the Contacts

Dirt on the electrical contacts between the cartridge and the carriage makes the printer misread the cartridge — often as empty or missing entirely, even when it is full.

Remove the black cartridge.
Rub the copper contacts on the cartridge gently with a clean, dry pencil eraser.
Do the same to the matching contacts inside the printer carriage.
Reseat the cartridge firmly until it clicks.

This resolves "cartridge not detected" and "missing ink" errors in a high percentage of cases.

Two details worth getting right. Use a lint-free cloth — microfibre or clean cotton — for any wiping, not a paper towel, because paper fibres come off on the contacts and cause exactly the fault you are trying to clear. And if you use any liquid, use distilled water on the cloth rather than on the cartridge, and let everything dry completely before reinstalling.

5. Align the Printhead

Once black ink is flowing again, alignment is what makes it look sharp.

Run it from Setup > Tools > Align Printhead on most HP printers, or through HP Smart. The printer prints a page of grids and squares; you either scan it back in or pick the best-looking squares from the front panel.

People skip this step, and it matters more than it sounds. A misaligned printhead can produce text that looks faded or doubled — which reads as an ink problem and sends you back round the cleaning cycle for nothing.

6. If You Just Installed a New Cartridge: Pull the Tape

New HP cartridges ship with two protective pieces: tape over the nozzle plate, and a plastic clip protecting the contacts. If you didn't peel both off, the cartridge will print nothing.

Take the cartridge out again.
Remove every piece of orange or clear plastic.
Reinstall.

Check the tab came out in one piece. A pull-tab that snapped off partway leaves most of the seal in place, and the cartridge behaves exactly like a dead one.

7. Print the Print Quality Diagnostic Report

If you are guessing about which cartridge is at fault, stop guessing. Every HP inkjet can print a diagnostic page that answers the question directly.

Look for Settings > Reports > Print Quality Report, or Print Quality Diagnostic Page on older models — and on printers without a display, it is in HP Smart under Printer Tools, or in the printer's embedded web page under Tools or Reports.

The page prints a solid bar of each ink colour plus a block of black text. Read it like this:

Black bar missing entirely — no black ink is reaching the paper. Empty cartridge, blocked nozzles, or a cartridge the printer has rejected. Fix 1, Fix 2, Fix 3.
Black bar streaky or full of white lines — partial clog. This is the one cleaning cycles fix well.
Black bar solid but your documents still print pale — the printhead and cartridge are fine. The fault is alignment (Fix 5) or a driver setting (Fix 10).
A colour bar missing while black is fine — that colour is the problem, and on many models it is also the reason the whole job is being blocked. Fix 9.

Print this before you start replacing anything. It takes one sheet and it removes most of the guesswork from every step above.

8. Power-Cycle the Printer Properly

Not the power button on the front — a real one. HP printers hold cartridge state in the controller, and a soft error there can persist through a normal restart, keeping a perfectly good cartridge flagged as failed.

Turn the printer off with its own power button, waiting for it to shut down rather than pulling the plug mid-cycle.
Unplug the power cable from the back of the printer and from the wall.
Wait sixty seconds.
Plug it directly into a wall socket rather than a surge strip or extension lead for this test.
Power on and let the printer finish its start-up routine before printing.

This clears soft errors in the controller and forces a fresh read of the cartridges. It is worth doing after reseating cartridges, and it is the reason a cartridge that read "empty" sometimes reads correctly again afterwards.

One caution: pulling the plug while the carriage is mid-travel can leave the printhead parked away from its capping station, where it will dry out faster. Always let the printer shut down properly first.

9. The Low-Ink Interlock: When One Empty Cartridge Blocks Everything

This is the fix that saves the most wasted effort, because the symptom looks nothing like the cause.

If any cartridge in an HP inkjet reads empty or very low, the printer can refuse the entire job — including a plain black text document that does not need that colour at all. The reason is genuine rather than commercial: firing a nozzle with no ink behind it has nothing to carry the heat away, and the nozzle burns out. Blocking the job protects the printhead.

What makes it confusing is how it presents. Sometimes there is a clear message on the printer. Sometimes the job just sits in the queue. Sometimes the driver reports the printer as offline and says nothing about ink at all.

So if black has stopped and you have not looked at the other three cartridges, look now:

Check every cartridge, not just black, on the printer's own screen or in HP Smart.
Treat "very low" as empty for this purpose — the block often starts before the level reads zero.
Replace whichever cartridge is flagged, even if you have no intention of printing that colour.

Some models offer an override that lets you continue at your own risk, usually presented as a prompt on the printer's screen the first time it stops. Plenty of current firmware versions do not offer it at all. If yours does not, replacing the cartridge is the only way through — there is no setting hidden in the driver that unlocks it.

Worth knowing: HP Smart can show stale ink levels after the printer has been asleep, so a cartridge that reads fine in the app may still be the one stopping the job. Read the levels from the printer's own control panel, or power-cycle first (Fix 8) and check again.

10. Check You Are Not Printing in Grayscale, Draft or Ink-Saver Mode

Before concluding anything is wrong with the hardware, rule out the driver. These settings are easy to enable by accident and they survive across documents.

Print in Grayscale. Under Printer properties > Preferences > Colour, or the Colour tab of the print dialog. On some HP drivers this offers two options: Black Ink Only and High Quality Grayscale. The second one builds grey out of colour ink — so if your black cartridge is dead and this is selected, everything still prints, and it prints in that brownish composite black. Set it to Black Ink Only to force the black cartridge and prove whether it works.
Draft or EconoMode. Lays down so little ink that text can look almost absent, especially on cheaper paper. Set quality to Normal and reprint before troubleshooting further.
Paper type set wrong. If the driver thinks it is printing on photo or transparency media, it changes how much ink it puts down and how it dries. Set it to Plain Paper for a test.
Wrong printer selected entirely. Windows will happily route jobs to a PDF writer if "Let Windows manage my default printer" is on. Turn that off in Settings > Bluetooth & devices > Printers & scanners.

The fastest test for all of these: open Notepad, type a sentence, and print it with quality set to Normal and colour set to Black Ink Only. If that comes out black, the printer is fine and the original job's settings were the problem.

Smart Tank and Refillable Models Are Different

If your HP is a Smart Tank, the cartridge advice above does not apply, because there are no cartridges — and black failing on a tank model has its own short list of causes.

Air in the black line. If the black tank ran dry, refilling it is not enough; air has been drawn into the tube and has to be pulled through. Use the printer's deep clean or ink flush routine rather than the standard cleaning cycle.
The initial ink charge never completed. On a newly set up machine, the routine that pulls ink from the tanks to the head takes several minutes and must not be interrupted. If it was, black is often the colour that suffers.
The valve or transport lock is still closed. Check the position before assuming a fault.
The printhead is a serviceable part on these models. That is good news compared with a sealed OfficeJet head — a failed head does not automatically write off the printer.

Deep clean routines on tank printers use considerably more ink than a standard cleaning cycle. Run one when you have a reason, not as a first move.

What If You're Using a Compatible or Remanufactured Cartridge?

HP firmware can reject third-party cartridges with a "cartridge problem" or "counterfeit cartridge" warning, and it happens most often shortly after a firmware update has installed itself.

HP has rolled back a few of these updates after customer complaints, and reverting to older firmware sometimes restores compatibility — though that needs doing carefully, and it is worth turning off automatic firmware updates in the printer's web services menu once you have a working setup.

We test every cartridge we sell against current HP firmware, and if one is rejected on your machine we will sort it out.

Before assuming the cartridge is the problem, though, work backwards: a rejection message on a compatible cartridge is sometimes just dirty contacts (Fix 4) or a cartridge that has not seated fully. Reseat it, clean the contacts, power-cycle (Fix 8), and see whether the message returns.

When It's Time to Replace the Whole Printhead

On HP OfficeJet Pro and some Photosmart models the printhead is a separate replaceable part, not built into the cartridge. After a few years of heavy use these can fail outright, and cleaning cycles won't help.

Once you have worked through everything above, check the model-specific guides for your printer — the OfficeJet Pro 8620 and OfficeJet 8015 pages are good examples — to find the exact part number and work out whether a new printhead is worth more than a new printer.

The signs that point at a dead head rather than a clog: three cleaning cycles and a manual wipe have changed nothing, the diagnostic page shows the black bar completely absent rather than streaky, and a known-good cartridge behaves the same way. A clog usually improves at least slightly with cleaning; a failed head does not move at all.

One More Thing: Print Something Once a Week

The single best thing you can do to prevent this problem from coming back is to print regularly. Even a blank page with a black line on it will keep ink flowing through the nozzles.

Inkjets are not designed to sit unused for months at a time, and printhead drying is the root cause of probably 80% of the "won't print black" calls.

Two things that help alongside it: leave the printer plugged in and powered rather than switching it off at the wall, so it can run its own maintenance routines and park the head in its capping station; and keep it out of direct sun and away from heat sources, which dry the nozzles faster than idleness alone.

Frequently Asked Questions

Why is my HP printing colour but not black?

The black nozzles have dried while the colour ones stayed wet — normal if you print infrequently or mostly print colour. Black pigment ink dries harder than colour dye ink, so it is usually the first to clog.

How many cleaning cycles should I run?

Three at most, with a test print between each. Every cycle pushes ink through the nozzles and into the waste pad, so a fourth and fifth cycle cost real ink for very little additional chance of success. If three have not worked, move to wiping the head by hand.

Why does my HP refuse to print black when only a colour cartridge is empty?

Because firing a nozzle with no ink behind it can destroy the printhead, so the printer blocks the whole job rather than risk it. It is a protection measure, and on most current firmware it cannot be overridden. Replace the empty cartridge — whichever colour it is — and black printing returns.

Is my new compatible cartridge faulty?

Check the obvious things first: the protective tape is fully off, the contacts are clean, and the cartridge is seated all the way in. Then put a different cartridge in to isolate the fault. If it really is defective, any supplier worth buying from will replace it without argument.

What does the print quality diagnostic page actually tell me?

It prints a separate solid bar for each ink, so it shows you which cartridge is failing rather than leaving you to infer it. A missing black bar means no black ink is reaching the paper at all; a streaky one means a partial clog that cleaning will usually fix; a solid black bar alongside pale documents means the fault is alignment or a driver setting, not ink.

Can a clogged printhead be permanently ruined?

Yes — ink left to dry for months can set hard enough that nothing shifts it. On cartridge-mounted heads that just means a new cartridge. On separate heads it can mean a replacement head, which on cheaper models costs enough that replacing the printer becomes the sensible option.

Why is my black text coming out brown or grey?

The printer is building composite black from cyan, magenta and yellow because the black cartridge has nothing left, or because the driver is set to High Quality Grayscale rather than Black Ink Only. Check the driver setting first — it is free — then check the black cartridge by weight.

Does printing regularly actually prevent this?

It does. Printing a single page with some black on it once a week keeps ink moving through the nozzles and uses far less ink than the cleaning cycles you would otherwise need after a month of idleness.
