Troubleshooting issues on Epson WF-3820

1. Accessing Maintenance Mode

• Power on the printer and ensure it is connected to a power source and a computer (if applicable).
• From the touchscreen, select the Home button.
• Navigate to the Settings or Maintenance option.

2. Print Head Alignment Process

• In the maintenance menu, select the Print Head Alignment option. Most Epson models offer two types of alignment:
  • Vertical Alignment: Corrects the vertical displacement of printed lines.
  • Horizontal Alignment: Adjusts horizontal lines to prevent images from appearing blurred or out of focus.

3. Print Test Page

• The printer will print a page with test patterns consisting of parallel lines.
• Review the printed patterns. You will need to select the lines that best align with each other. The printer's screen will prompt you to enter the corresponding number or letter for the most accurate pattern. This step is critical, as misaligned lines can result in blurry or poorly defined prints.

4. Automatic or Manual Adjustment

• Some printers offer both automatic and manual alignment options. If you select automatic, the printer will make adjustments based on the sensor readings of the printed patterns. If you choose manual, you will continue to visually select the best alignments.

5. Final Review

• Once the alignment is complete, it is advisable to print a test page or document to verify that the print head is properly aligned and that there are no displacement issues in the prints.

6. Additional Solutions

• If you continue to experience issues after performing the alignment, it may be necessary to clean the print heads. This option is also available in the maintenance menu. Cleaning will help eliminate any blockages in the print head nozzles.
• If the problem persists, the print head may be damaged or require replacement. It is also advisable to check for available firmware updates on the official Epson website, as some updates resolve printing and alignment issues.

Technical Considerations:

• Use of Appropriate Paper: Ensure that the paper is compatible with the printer, as using low-quality paper can affect alignment.
• Periodic Maintenance: Regular cleanings and alignments help prevent future issues and maintain optimal print head performance.

This procedure ensures proper alignment of the print head, guaranteeing precise and sharp prints.
