Nozzle Check Printer Test Page
Detect clogged or misfiring inkjet nozzles with this diagnostic test page. Individual rows of fine lines for each ink channel make it easy to spot gaps, breaks, or missing nozzles.

How to Use This Test Page
- Load plain white paper into your inkjet printer.
- Click the “Print This Page” button above.
- In the print dialog, select “Color” mode and “Best” quality to ensure all nozzles fire.
- Print the page and examine each color channel row under good lighting.
- If gaps are found, run a head cleaning cycle and reprint to verify improvement.
What to Look For
- All lines should be present in every channel row — no gaps or missing segments.
- Lines should be continuous with no breaks, skips, or white streaks cutting through them.
- Ink density should be consistent across each row from left to right.
- Each color channel (Cyan, Magenta, Yellow, Black) should be complete with full coverage.
- There should be no cross-contamination of ink colors between adjacent channel rows.
Troubleshooting Tips
- Gaps or missing lines in one or more channels
- Run your printer’s head cleaning cycle. If gaps remain after two cleanings, let the printer rest for an hour, then try again.
- Faint or inconsistent density across a channel
- The ink cartridge may be running low. Check ink levels and replace the cartridge if necessary.
- Lines appear in the wrong color or are mixed
- Verify that all ink cartridges are installed in the correct slots. Reseat any cartridges that may be loose.
