How to Fix Print Quality Issues on Epson EcoTank and Expression Printers

Applies To

  • Operating Systems: Windows 10, Windows 11, macOS

  • Hardware: Epson EcoTank and Expression Series Printers (e.g., ET-4950, ET-4850, L6390, XP-2200, and similar models)

  • Software: Epson Printer Driver

Description

If your Epson EcoTank or Expression printer is printing blank pages, has blurry text, or is missing a colour (for example, yellow, cyan, magenta, or black), run a Nozzle Check followed by Head Cleaning via the printer driver Maintenance menu. For severe clogs, a Power Cleaning may be required (for models where this feature is available).

Symptoms

Perform these steps if your printer exhibits any of the following issues:

  • Faint Output: Printed text or images appear faded or light.

  • Banding: Horizontal white lines or streaks appearing across the page.

  • Incorrect or Missing Colours: One or more colours — yellow, cyan, magenta, or black — are missing, faint, or look distorted in printed output.

  • Blank Pages: The printer runs, but no ink appears on the paper.

  • Broken Nozzle Pattern: A Nozzle Check printout shows gaps or missing segments.

Solution

1. Preparation and Safety

  • Check Ink Levels: Ensure all ink tanks are filled above the lower limit line. Running cleaning cycles with low ink can damage the printer.

  • Power Management: Do not turn off the printer or open the scanner unit during a cleaning cycle.

  • Paper: Load a few sheets of plain paper into the rear feed or paper cassette.

2. Accessing the Maintenance Menu

The cleaning utilities are located in the printer driver settings. Use the quick reference table below, or the detailed steps for your operating system further down.

Cleaning Methods Overview

Cleaning Type When to Use Description
Nozzle Check Before & after cleaning Prints a test pattern to identify clogging.
Head Cleaning Mild/moderate clogging Standard cleaning cycle to clear blocked nozzles.
Power Cleaning (if available) Severe clogging or repeated failures Deep clean that uses more ink.

3. Cleaning Procedures

These steps apply to all supported operating systems. Open the menu identified for your OS in the Quick Reference table above: the Maintenance tab (Windows 11 / Windows 10) or the Printer Utility window (macOS).

Step A: Run a Nozzle Check

  1. In the Maintenance tab (Windows) or Printer Utility window (macOS), click Nozzle Check.

    Nozzle Check button (Windows). macOS: see Nozzle Check icon in Step 2 above.
  2. Click Print.

  3. For each colour, check the printed pattern against the example below to see if the print head nozzles are clogged.

    Nozzle Check pattern examples: A) OK — solid, unbroken horizontal lines; B) NG — lines with some visible gaps and breaks; C) NG — lines mostly broken and fragmented with large gaps
    • A) OK: the horizontal lines print solid and unbroken, with no visible gaps — no further steps are needed.
    • B) NG: the lines are mostly present, but show some visible gaps or breaks — proceed to Head Cleaning (Step B).
    • C) NG: the lines are mostly broken up or fragmented, with large gaps throughout — proceed to Head Cleaning (Step B); if there's no improvement after cleaning, Power Cleaning (Step C) is likely needed.

  4. The driver's Nozzle Check window also shows this comparison directly on screen alongside your printed result, letting you select the matching option and proceed straight to Head Cleaning from there if needed.

Note: The pattern shown above is a general example — the exact nozzle pattern can vary by printer model. For the most accurate comparison, follow the on-screen guidance in the driver's own Nozzle Check window, or check your product's user manual for a model-specific example.
Troubleshooting Matrix
Symptom Recommended Action
All lines are printed No further steps are needed
Some nozzles are clogged (image B) Perform Head Cleaning (Step B); repeat up to 3x
Blank page or most lines are missing (image C — more than 50% missing) If available, perform Power Cleaning (Step C); otherwise perform Head Cleaning (Step B), repeat up to 3x
No improvement after 3 cleanings (Step B) If available, perform Power Cleaning (Step C)

Step B: Head Cleaning

  1. In the Maintenance tab (Windows) or Printer Utility window (macOS), click Head Cleaning / Print Head Cleaning. For some driver versions if a Maintenance button appears instead, click that first.

    Head Cleaning button (Windows). macOS: see Head Cleaning icon in Step 2 above.

  2. Click Start and wait for the process to complete (the power light will stop flashing).

  3. Run another Nozzle Check. If the pattern is still broken, repeat this cleaning up to 3 times.

  4. If print quality does not improve after a head cleaning:

    1. If Power Cleaning is not available:

      1. Turn the printer off using the printer's Power button. This ensures the print head is capped correctly to prevent it from drying out.

      2. Wait 12 hours.

      3. Repeat Head Cleaning (steps 1–3 above).

    2. If Power Cleaning is available, continue to Step C.

Step C: Power Cleaning

  1. In the Maintenance tab (Windows) or Printer Utility window (macOS), click Power Cleaning or Power Ink Flushing. For some driver versions if a Maintenance button appears instead, click that first.

    Power Cleaning button (Windows). macOS: see Power Cleaning icon in Step 2 above.

    Power Ink Flushing button (Windows). macOS: see Ink Flushing icon in Step 2 above.

  2. Follow the on-screen prompts. Ensure you have enough ink (at least 1/3 full).

  3. Once finished, run a final Nozzle Check.

  4. If print quality does not improve after a Power Cleaning:

    1. Turn the printer off using the printer's Power button. This ensures the print head is capped correctly to prevent it from drying out.

    2. Wait 12 hours. This allows trapped air to dissipate and dried ink to soften before trying one more standard cleaning.

How to Prevent Clogged Print Heads

  • Print Weekly: Print at least one colour test page per week to keep ink flowing.

  • Power Down Correctly: Always use the Power Button on the printer. This "caps" the print head to prevent it from drying out. Never unplug the power cable whilst the printer is on.

  • Environment: Avoid placing the printer in direct sunlight or near a heater, as heat evaporates ink in the nozzles.
