If your printer suddenly starts streaking, printing faded colors, or spitting out blank pages, there’s a good chance you’re dealing with a clogged printer cartridge. This issue affects nearly every inkjet printer owner at some point—and in an industry worth more than $19 billion, it’s one of the most common frustrations.
The good news? A clogged cartridge usually leaves very obvious clues, and once you know what to look for (and how to fix it), you can get your printer running smoothly again.
Before you start manually cleaning anything, you need to be sure the problem is actually a clog. The easiest way is to run your printer’s built-in diagnostic test.
Epson printers: Go to Setup → Maintenance → Nozzle Check.
HP printers: Open the HP Smart App → Tools → Print Quality Report.
Canon printers: Use Maintenance → Print Nozzle Check Pattern.
This test prints a pattern of thin lines for each ink color.
If you see gaps, broken lines, missing colors, or streaking, it’s almost always a clog.
Below is a quick guide to match what you see on paper with what’s happening inside your printer.
| Symptom | Cause | What to Do First |
|---|---|---|
| Horizontal White Lines | One or more completely blocked nozzles | Run a Nozzle Check, then cleaning |
| Faded or Wrong Colors | Partial clog in a specific ink color | Print a quality report & identify the color |
| Blank Pages | Severe clog or dried-up printhead | Check ink levels, then perform Head Cleaning |
| Blurry or Shadowed Text | Misalignment or uneven spray pattern | Run Printhead Alignment, then re-test |
These clues help you diagnose the problem before wasting time and ink on the wrong fix.
Not all printers work the same way—and where the clog forms determines how you fix it.
These cartridges have the printhead attached.
If the clog is stubborn, replacing the cartridge usually solves everything.
Examples: HP 63, 65, 67 series
Ink cartridges are just ink tanks, and the printhead lives inside the printer.
These require manual printhead cleaning, which is more delicate.
Example: Epson EcoTank printers
Before cleaning anything, check what type of system your printer uses.
Once you’ve confirmed a clog, start with the gentlest method and work your way up.
Every inkjet printer has a “Clean Printhead” or “Head Cleaning” function that forces ink through the nozzles.
Print a Nozzle Check test page.
Run Head Cleaning once.
Print another Nozzle Check.
If it improves, you may run one more cycle—but stop after two.
Important: Printhead cleaning uses a lot of ink. Repeating it 4–5 times wastes ink without helping a severe clog.
If the problem persists after two cycles, move to manual cleaning.
This easy method works great when a color looks faint or has small gaps.
Dampen a lint-free cloth with warm distilled water.
Gently press the nozzle plate (the metallic strip) onto the cloth.
Hold for 2–3 seconds.
Repeat on a clean section of the cloth until all colors appear.
You should see clear, sharp ink blots. If not, move to a deeper cleaning method.
This approach removes hardened ink that’s been sitting for months.
Pour ½ inch of warm distilled water into a shallow dish.
Place only the nozzle plate of the cartridge into the water—never the copper contacts.
Soak for 3–8 hours (overnight for severe clogs).
Pat dry with a clean, lint-free cloth.
Reinstall & run one cleaning cycle.
Never use boiling water—it can warp components.
Do NOT scrub the nozzles.
Avoid tap water; minerals can create new clogs.
If the cartridge still won’t print properly, it may be damaged beyond repair.
Preventing clogs is far easier than fixing them.
Ink dries when it sits. A simple color page once a week keeps nozzles flowing.
Cheap third-party inks often use formulas that dry faster and clog more easily.
Research by SpencerLab found up to 58% of remanufactured cartridges fail during normal use—often because of poor ink quality.
Always use the power button, not the wall plug.
This parks the printhead in a sealed position to prevent drying.
Heat, dryness, and sunlight accelerate ink evaporation.
Sometimes a cartridge is too far gone. Replace it when:
The nozzle plate has visible scratches or damage
You’ve soaked and cleaned it but still see missing colors
The printer repeatedly gives a “Cartridge Not Recognized” error
You’ve spent more time cleaning than the cartridge is worth
Consider whether your time is more valuable than a $15–$30 cartridge.

Only when print quality noticeably declines.
Running it too often wastes ink.
No. Use distilled or deionized water to avoid mineral buildup.
Not really—and it can cause leaks inside your printer.
If left untreated for long periods, yes. Ink can harden inside the printhead.
