Is your once-reliable Epson EcoTank ET-2720 printer now spitting out patchy prints or blank pages? Before you resign yourself to a new printer, there might be a solution – manual print head cleaning. However, this process is for advanced users only and requires a steady hand and a good understanding of delicate electronics. One wrong move can damage your printer beyond repair.

How do you clean Epson EcoTank print head nozzles which are blocked or clogged?

Consider the Alternative: The Power Cleaning Cycle

Before diving into the disassembly process, consider trying the power cleaning cycle mentioned in a previous blog post. This built-in function on the ET-2720 can often resolve clogged print head issues without the need for dismantling your printer. It’s a much safer option to try first.

If Manual Cleaning is Unavoidable: Proceed with Caution

The following steps are for informational purposes only and should not be taken as a recommendation to attempt manual cleaning yourself.

Step 1: Assess the Risks

This is a complex procedure with many opportunities for missteps. Attempting manual cleaning is a risky venture and could result in permanent damage to your printer. If you are not comfortable with intricate tasks involving delicate electronics, stop here and consider seeking professional help.

Step 2: Prepare for Disassembly (Proceed with Caution)

Disassembling the printer requires extreme care and precision. Every step needs to be followed meticulously to avoid causing damage. Here’s a breakdown of what’s involved:

  • Unlocking the Print Head: This involves initiating a copy process and then unplugging the power cable mid-print to catch the print head in motion.
  • Removing the Print Head Cover: Several specific panels need to be unscrewed to access the print head itself. Be mindful and avoid using excessive force.
  • Detaching the Print Head Carriage and Cables: This step requires the utmost caution due to the fragile components involved. One wrong move can cause permanent damage.
  • Taking Out the Print Head and Ink Cartridges: Once the carriage is removed, you can carefully extract the print head and the ink cartridges.

Step 3: Cleaning the Print Head (Use Distilled Water with Caution)

  • With the print head removed, you can clean it using a lint-free tissue and distilled water. Avoid using tap water or any cleaning solutions, as these can damage the delicate components.
  • Gently dab the print head with the damp tissue, removing any visible ink buildup. Be meticulous and avoid touching the electrical contacts.

Step 4: Reassemble the Printer (The Reverse of Disassembly)

Once the print head is cleaned, it’s time to reassemble the printer in the exact reverse order of disassembly. Every step needs to be followed carefully to ensure everything is put back together correctly.

Important Considerations Throughout:

  • Meticulous Attention to Detail is Key: Every step requires focus and precision to avoid damaging the printer.
  • Use the Right Tools: Don’t use any tools that are not specifically designed for working with electronics.
  • When in Doubt, Seek Help: If you’re unsure about any step, stop immediately and consult a professional technician. A little professional help is much cheaper than a new printer!

Step 5: Verify Your Success

  • Run a Print Head Cleaning Cycle: Once the printer is reassembled, navigate to the settings menu and initiate a print head cleaning cycle.
  • Perform a Nozzle Check: Print a nozzle check pattern to see if the cleaning was successful. Look for a complete and even distribution of ink across all colors.
  • Test Print for Confirmation: Print a test page to confirm that all colors are printing correctly and there are no more streaks or missing colors.

Remember: Prevention is Key

While manual print head cleaning can be a last resort, it’s certainly not ideal. Here are some ways to prevent clogs and the need for such drastic measures:

  • Regular Printing: Even a simple test page printed every now and then can help keep the ink flowing freely and prevent clogs.
  • Genuine Epson Ink: Using genuine Epson ink cartridges formulated for your printer can minimize clogging risks. Compatible inks can sometimes cause issues.
  • Cleaning the Exterior: Regularly wiping down the printer’s exterior with a soft, dry cloth helps prevent dust and debris from accumulating inside the machine, which can contribute to clogs.

The Final Word: Weigh the Risks Carefully

Manual print head cleaning is a risky procedure for the Epson EcoTank ET-2720. If you’re not comfortable with the process or the potential consequences, it’s highly recommended to try the power cleaning cycle or seek help from a professional.
