My prints have horizontal lines evenly spaced across the page but the nozzle check looks fine. What else could it be?

Evenly spaced horizontal lines that aren't related to nozzle clogs are often caused by a dirty or misaligned paper feed roller, or by printhead alignment being off. Run the printhead alignment utility in your printer's maintenance software — this prints a test page and adjusts the timing of the printhead sweeps to eliminate banding.

I ran three cleaning cycles and the streaks are worse. Did I make it worse?

Running too many cleaning cycles in quick succession can push the clog deeper or cause air bubbles in the ink channel. Stop running cycles and let the printer sit for a few hours. Then do a manual soak cleaning with a damp lint-free cloth pressed against the nozzle plate for 30–60 seconds. This usually softens the dried ink enough for the next cleaning cycle to flush it through.

Faded or Streaky Prints? How to Clean Your Printer's Printheads

Streaky, faded, or banded prints are almost always caused by clogged printhead nozzles — the tiny openings that spray ink onto the paper. Ink dries and hardens in these nozzles when the printer sits idle, especially in warm or dry environments. The good news is that most clogs clear up with a cleaning cycle or two.

Step 1: Print a Nozzle Check Pattern

Before cleaning, print a diagnostic nozzle check to see exactly which nozzles are blocked. This saves ink by not running cleaning cycles unnecessarily.

HP: Open HP Printer Assistant > Maintain Your Printer > Print a Test Page, or go to HP Smart and select Print Quality Diagnostics.
Epson: Open Epson Printer Utility > Nozzle Check.
Canon: Open the Canon IJ Utility > Test Print > Nozzle Check, or press the printer's maintenance button on the panel.
Brother: On the printer panel, go to Ink > Test Print > Print Quality.

The nozzle check produces a grid of lines or color blocks. Missing or broken lines show which color nozzles are clogged.

Step 2: Run the Software Cleaning Cycle

In your printer's maintenance software, run a Head Cleaning or Printhead Cleaning cycle. This takes 1–3 minutes. Afterward, print the nozzle check again to see if the gaps have cleared. If there are still missing lines, run a second cleaning cycle.

Important: Don't run more than 2–3 cleaning cycles in a row without a break. Each cycle uses a small amount of ink and can put wear on the printhead. If two cycles don't fix it, move to the manual method.

Step 3: Manual Printhead Cleaning

For stubborn clogs, you can clean the printhead manually:

Power off the printer and open the ink cartridge access cover.
Remove the ink cartridges.
On many HP and Canon printers, the printhead is built into the carriage (not the cartridge). Look for the copper nozzle plate on the bottom of the printhead or carriage.
Dampen a lint-free cloth with warm distilled water. Gently press the cloth against the nozzle plate for about 30 seconds — don't scrub, just hold it to soak the dried ink.
Use a fresh damp cloth to gently wipe the nozzle plate once. Let it air dry for 10 minutes.
Reinstall cartridges, power on, and run the nozzle check again.

Step 4: Deep Cleaning (Epson)

Epson printers offer a Power Cleaning option (separate from standard cleaning) accessible in Epson Printer Utility. This uses more ink but shifts harder clogs. Use it only once, then wait and test.

Preventing Future Clogs

Print at least one page per week to keep the ink flowing through the nozzles.
Store the printer in a location without extreme temperature swings.
Use genuine manufacturer ink — third-party inks can have different viscosity and clog more easily.

If the nozzle check still shows gaps after manual cleaning, the printhead may need replacement. Ask us for guidance on whether to replace the head or the printer.
