For inkjet printers
Printer Nozzle Test
Print a nozzle test page to check missing lines, gaps, weak ink channels, and uneven inkjet output.

Nozzle test sheet
What you see below is exactly what prints: six labeled sections on a single page.
1 Black
Solid pattern for checking consistent ink coverage.
2 Cyan
Solid pattern for checking consistent ink coverage.
3 Magenta
Solid pattern for checking consistent ink coverage.
4 Yellow
Solid pattern for checking consistent ink coverage.
5 Fine-line staircase
Secondary check for intermittent gaps and broken output.
6 Composite pattern
Quick overall comparison.
Recommended next test
Small gaps appear in one color.
May indicate a partially blocked nozzle. Run the printer's built-in check.
Large sections are missing.
May indicate several blocked nozzles. Use the printer's maintenance.
Gaps repeat at regular intervals.
May indicate a repeating printhead issue. Use the built-in check.
Compare
Did cleaning improve the result?
Print the same pattern again and compare:
Improvement. If a few gaps remain, run one more standard cycle, then compare again.
No change. Run one standard cleaning cycle, then confirm with the built-in nozzle check.
Stop cleaning and let the printer rest. Check ink levels, then use the built-in nozzle check.
The affected area moved. Confirm with the built-in nozzle check before cleaning again.
Follow your printer manufacturer's cleaning procedure. Avoid repeated deep-clean cycles unless the manual advises them.
For the most accurate nozzle diagnosis, use your printer's built-in nozzle check when available.
PrinterInspect provides a general visual nozzle test. A manufacturer's built-in nozzle check is designed around that printer's specific printhead and maintenance system.
Printer Nozzle Test vs Printer Alignment Test
- Printer Nozzle Test checks whether fine ink lines contain gaps, missing segments, or weak output.
- Printer Alignment Test checks positioning, skew and print alignment.
Compatibility
Printer compatibility
Best for:
- Inkjet printers
- Color inkjet printers
- Photo inkjet printers
Not intended for laser printers:
Laser printers use toner rather than inkjet nozzles, so this test is intended for inkjet printers.
Important:
Visual test only: This page can reveal visible gaps, missing lines, and uneven output. Results can also be affected by paper, ink delivery, print settings, and printer condition. It cannot read ink levels or identify a specific failed component.
FAQ
Nozzle test questions
What is a printer nozzle test?
A printer nozzle test prints fine patterns for each ink color so you can check for missing segments, gaps, weak output, and uneven ink coverage.
How do I run a nozzle test on an inkjet printer?
Print the test page at 100% / Actual Size on plain white paper. Inspect each color pattern for gaps, missing sections, and uneven output.
What do missing lines on a nozzle test mean?
Missing lines or segments can indicate an ink delivery problem, but they can also be affected by ink condition, print settings, paper, or printer maintenance.
Why is one color missing from my nozzle test?
A missing color pattern can be related to that color's ink supply or ink delivery system. Check the cartridge or ink tank and follow your printer manufacturer's recommended maintenance procedure.
Should I clean the printhead if I see gaps?
If your printer provides a printhead or nozzle-cleaning function, follow the manufacturer's recommended procedure. Avoid repeated deep-clean cycles unless the printer manual recommends them.
Why should I compare the nozzle test before and after cleaning?
Printing the same test again lets you see whether the gaps or missing sections have changed. Improvement suggests the cleaning procedure affected the visible output, while an unchanged result may require further troubleshooting.
Can I use a nozzle test on a laser printer?
No. This page is designed for inkjet printers. Laser printers use toner rather than inkjet nozzles and require different print-quality checks.
