A nozzle check is a printer-generated pattern used to inspect inkjet output. Use the exact model's supported control-panel or driver route, then look for gaps or missing colour sections. It is not the same as a photograph, a Windows test page, an alignment sheet or a photocopy.

A pattern can show that output is incomplete, but it does not by itself prove which component or cartridge is at fault.
Find the right procedure
Look up the complete printer model in its manual. For example, Epson's XP-3100 Windows guidance uses the printer driver's Maintenance tab and Nozzle Check. Another model or a generic operating-system driver may present different controls.
Do not download an unknown utility merely because the option is not visible. Check that the installed software is the supported software for the exact machine and operating system, or use the documented panel route where available.
Load the paper type and size required by the procedure. Follow the prompts and keep hands away from moving parts. A nozzle check is an inkjet function; a laser printer needs its own print-quality report.
Keep the first pattern
Write the date and any recent cartridge change on the back. Check each labelled colour or section and compare it with the manual's example. Do not rely on memory when deciding whether the next attempt is better.
| Pattern observation | What it suggests checking next |
|---|---|
| Every expected section complete | Document, paper, settings or another symptom |
| Gaps in a section | Model-supported nozzle/quality guidance |
| Whole channel absent | That supply and supported quality checks |
| Entire page blank | Broader blank-output investigation |
| Printer refuses to print a pattern | The exact error or operating condition |
A line that should be absent in the manufacturer's example is not a defect. Read that example rather than assuming every white space on a test sheet is a blocked nozzle.
Distinguish nozzles from alignment
Broken output within a channel and displaced or doubled alignment marks are different observations. Do not run alignment simply because the word lines appears in your description, or cleaning simply because a photograph looks different from the screen.
If the nozzle pattern is complete, check the paper type, print quality and colour settings relevant to the original job. If the issue occurs only in copying, investigate the scanner path too.
A full ink indicator does not replace this pattern. It describes a status or estimate, not a direct observation that every nozzle is printing correctly.
If cleaning is indicated
Use the exact manual's routine and compare a new pattern after the supported step. Do not change several other settings at the same time, because that makes improvement harder to interpret.
Observe cycle limits and waiting periods. These differ between models; a number found for one Epson is not a universal instruction for all inkjets. Stronger or power-cleaning options can have additional level and maintenance requirements.
Do not keep repeating cleaning until the ink indicator falls. No improvement is a reason to pause and reassess. Avoid solvents, forced flushing or dismantling a head based on a generic diagram.
If a replacement was just installed
Check the correct family, colour and supplied preparation instructions. If the printer says not recognised, resolve that message before treating the situation as a nozzle problem. See our recognition guide.
If supplies are accepted but the pattern has one missing channel, record that colour precisely. Do not buy another full set merely because one section is incomplete.
Use Find Ink if you need to verify the supply family. Exact model matching remains important even when diagnosing a fault rather than shopping.
Share useful evidence
Send the full model, the pattern before and after supported maintenance, the cartridge or bottle codes and a description of when the problem began. Include any error rather than cropping it away.
A clear pattern photographed under neutral lighting is more helpful than an edited photo that exaggerates a colour cast. State what you observed and what procedure was used without claiming a cause you have not established.
Is a normal document a nozzle check?
No. It includes application, file and settings choices that a model-generated pattern helps separate.
Should I clean if the pattern is complete?
Not automatically. Investigate the original symptom and settings first.
Can I compare patterns from different models?
Use the example for your own printer. Patterns and labels can differ.
What if the same gap remains?
Follow the exact stopping and waiting guidance, then seek support if it persists. Repetition without a limit is not a diagnosis.
