Run an Epson nozzle check when colors are missing, lines are broken, or the print shows banding. Use a Windows test page when you need to check the computer-to-printer connection. These tests answer different questions, and the exact menu or button sequence varies by model.

Choose the test that matches the symptom

Do not use a full-color photograph as the first diagnostic. It combines too many variables and makes the cause harder to isolate.

Run a nozzle check from the printer

1. Find the exact model number on the product label.
2. Load the plain paper specified in its manual.
3. Open Settings or Maintenance.
4. Select Print Head Nozzle Check and start the test.
5. Compare the result with the example for that model.

Button-only printers may require a model-specific power-on sequence. Use Epson Support to find the correct guide instead of trying a generic button combination.

Run the Epson utility in Windows or macOS

In Windows, select the printer under Printers & scanners, open its printing preferences or Epson utility, and choose Nozzle Check. In macOS, open Printers & Scanners, select the printer, then look under Options & Supplies or the installed Epson utility.

If only the Windows test page is needed, open Printer properties and select Print Test Page. A successful Windows page with a failed application print usually points to the application, selected printer, queue, driver, port, or paper settings rather than blocked nozzles.

Read the pattern before cleaning

• Complete lines: the nozzles are operating. Do not clean merely as a precaution.
• A few gaps: run one standard head-cleaning cycle, then print another check.
• Large missing areas: verify ink levels and follow the escalation procedure in the model guide.
• Complete but misaligned output: use alignment, not repeated cleaning.

Epson’s print-quality guidance shows the relationship between nozzle checks, normal cleaning, and model-dependent power cleaning. Follow the specific manual because cleaning limits and rest periods differ.

Separate a printer fault from a workflow fault

Print the nozzle check directly from the control panel when possible. If it is clean but the job remains wrong, check the RIP or application, color-management settings, media definition, driver, cable or network, and print queue. If the printer cannot produce its own clean pattern, solve that hardware or ink-flow issue before changing color settings.

Production UV printers use the same diagnostic principle but require additional checks for alignment, media height, white/color registration, curing, and ICC conditions. For direct-to-object work, review the compact UV flatbed application range only after defining the material, size, artwork, batch quantity, and durability requirement.

A maintenance record that supports faster troubleshooting

Keep the date, printer model, ink set, environmental conditions, cleaning action, and before/after nozzle patterns. A short record shows whether a defect appeared suddenly or deteriorated gradually and prevents different operators from repeating unnecessary cleaning.

Frequently Asked Questions

Can I run an Epson nozzle check without a computer?

Yes, many models can start it from the control panel. For button-only models, use the exact manual because the button sequence is not universal.

Is a Windows test page the same as a nozzle check?

No. A Windows test page checks communication and driver output; a nozzle check examines ink-channel firing.

How many times should I clean the printhead?

Use the limit and rest period stated in the manual for the exact model. Print a nozzle check between cycles and do not continue indefinitely.
