Keeping Your Epson Wide-Format Printer Nozzles Clear


Troubleshooting Clogged Print Head Nozzles: Causes, Symptoms, and Solutions

Are you experiencing banding on your prints, odd color shifts, or even blank pages emerging from your printer? The culprit might just be clogged print head nozzles. Don't panic—we've put togther a quick step-by-step guide to help you try to recover your printhead.


Understanding Nozzle Clogs: Causes

Let's talk about what causes these clogs in the first place:

  • Inactivity: Infrequent printing can dry up the ink in your print head, leading to nozzle blockages. Ensure regular nozzle checks to keep ink circulating or send a print through at least once a week, if not more!

  • Dusty Environments: Particles of dust can comprimise your printhead, causing blockages. Protect your printer from dust by covering it when not in use and considering a less dusty location.

  • Low Humidity: Dry air can dry out ink, resulting in clogs. Maintain humidity levels between 40%-60% or consider using a humidifier to counteract dryness.

  • Expired Inks: Expired inks can thicken or grow mold (for water-based ink), potentially damaging the print head. Always use fresh, unexpired inks stored in cool, dry conditions free from sunlight.


Recognizing Nozzle Clog Symptoms

Symptoms of clogged nozzles manifest as banding (horizontal white lines) or dramatic color shifts in prints. Banding occurs when nozzles fail to dispense ink properly, while color shifts or missing colors indicate specific nozzle problems.


Fixing Clogged Nozzles: Step-by-Step Solutions

Here's a troubleshooting guide to address nozzle clogs:

  1. Run Nozzle Check: Identify clogged color channels.

  2. Normal Head Cleaning: Attempt cleaning affected channels.

  3. Verify Cleaning: Check nozzle status post-cleaning.

  4. Repeat Process: If clogs persist, repeat steps 1-3, limiting attempts to three.

  5. Powerful Head Cleaning: Employ powerful cleaning if normal cleaning fails.

  6. Confirm Progress: Check nozzle status after powerful cleaning, reverting to normal cleaning to restore ink pressure if progress is evident.

  7. Consider Options: Evaluate warranty status for potential print head replacement or consider costs if out of warranty.


Preventive Maintenance: Be Proactive

The best defense against nozzle clogs is proactive maintenance:

  • Regular Usage: Print regularly to keep ink flowing.

  • Manual Nozzle Checks: Perform manual checks every 3-5 days, especially if printing infrequently. Address breaks in nozzle patterns promptly.


Conclusion: Keep Your Nozzles Clear

Maintaining printhead nozzles is essential for clean prints and uninterrupted printing. By understanding the causes, recognizing symptoms, and following troubleshooting steps, you can restore clogged nozzles and prevent future issues. Remember, proactive maintenance is key to keeping your printer in top shape.


If you've tried everything above and still cannot get your nozzle to print clearly, you may need to call Epson Technical Support for a service session to replace your printhead. Keep in mind, however, that out of warranty repairs can cost enough to warrant considering replacing the printer instead. We recommend calling Epson to get a quote for service then compare that against the cost of a new machine, to make the most educated decision based on your budget.
