Quick answer: Open the printer’s maintenance menu (on the printer screen or in the driver software), print a nozzle check, then run Head Cleaning and re-check. Repeat once if needed, then use Deep Cleaning a single time. Still streaky? Power off and let a warm, damp lint-free towel sit under the head for ten minutes, or soak cartridge-integrated heads in warm distilled water.
Step 1 – Print a nozzle check first
Maintenance menu > Nozzle Check (Epson), Print Quality Diagnostic (HP) or Nozzle Check Pattern (Canon). The page shows a grid per color: gaps and broken lines identify the clogged channel. This tells you whether cleaning helped, and prevents cleaning colors that were fine.

A syringe-based cleaning kit clears dried ink that software cleaning cycles can’t reach.
Step 2 – Run the built-in cleaning correctly
- Run Head Cleaning once, wait for it to finish, print the nozzle check again.
- Improved but not perfect: run it a second time.
- No improvement after two: run Deep / Power Cleaning once. It uses several times the ink, which is why it is not the first step.
- Let the printer rest an hour after a deep clean: softened ink sometimes clears on the next check without another cycle.
Step 3 – The manual rescue (when software fails)
Cartridge-with-head printers (most HP and Canon home models): remove the cartridge, hold a warm damp paper towel against the nozzle strip for ten minutes, blot until ink flows evenly, reinstall. Fixed-head printers (Epson EcoTank and similar): power off, place a few drops of a 50/50 mix of distilled water and isopropyl alcohol onto the capping station pad, park the head over it overnight, then run one cleaning cycle in the morning.
Step 4 – Keep it from clogging again
Print one color-containing page a week, keep the printer in a dust-free spot away from radiators, always power off with its own button (so the head parks and caps properly), and stick to decent ink. Printers that sit for months will clog regardless: schedule a weekly test page print if the machine is rarely used.
When cleaning stops being worth it
If a head needs rescuing monthly, the printer is telling you something. Tank-style inkjets clog less and cost pennies per page, and laser printers never clog at all: see our best multifunction inkjets and best laser printers for home offices, and the WiFi setup steps in our printer WiFi guide.
Frequently asked questions
Why do print heads clog?
Ink dries in the microscopic nozzles when the printer sits unused: a few weeks of idleness is enough for the first faint streaks, and months produce fully missing colors. Cheap refill ink and dusty environments speed it up. The single best prevention is printing a page or two every week to keep ink moving.
How many cleaning cycles should I run?
Two, maximum three, with a nozzle check between each. Every cycle pushes ink through the heads, so endless cleaning mostly empties your cartridges into the waste pad. If the pattern stops improving after the second cycle, switch to a deep clean once, and then to the manual method instead of repeating.
Can a fully dried head be saved?
Often, yes. On printers where the head is part of the cartridge, a warm damp paper towel under the nozzles for ten minutes works wonders. On printers with a fixed head, the distilled water and isopropyl soak through the capping station, left overnight, revives most stubborn clogs. Truly baked heads on years-idle printers are the exception.
Nozzle check, two cleanings, one soak if needed, and a weekly page to keep it from coming back. That routine saves both your prints and your ink budget.
