How to Fix Epson EcoTank 2720 Printer Refill Black Cartridge Error

Question:

I recently watched your video on the Epson EcoTank 2720 printer but couldn't find a solution to my problem. When I start the printer, the pump runs twice without any effect, then it tells me to refill the black cartridge. This error puts the printer in error mode, and I can't confirm that I have refilled the cartridge. When I try to validate, it says "invalid action." Despite having black ink in the final compartment and ink flowing, the issue persists. Should I reset the settings somewhere? If needed, I can provide a video of the issue.

It sounds like your Epson EcoTank 2720 printer is experiencing an issue where it cannot detect the ink level correctly, despite there being ink in the compartment. Here are a few troubleshooting steps you can try:

1. Power Cycle the Printer: Turn off the printer and unplug it from the power source. Wait for about a minute, then plug it back in and turn it on. Sometimes a simple power cycle can resolve sensor issues.
2. • Reset the Ink Level Counter:
   • On your printer's control panel, navigate to the settings menu.
   • Go to Control Panel -> Settings -> Maintenance -> Reset Ink Levels -> Start.
   • Follow the prompts to reset the black ink level.
3. Update Printer Firmware: Sometimes firmware updates can fix bugs related to ink detection. Check Epson's website for any available firmware updates for your model and follow their instructions to update your printer.
4. Run a Nozzle Check and Head Cleaning: Perform a nozzle check to see if the printer is able to print the test pattern. If the pattern is missing lines or is faint, run a head cleaning cycle. This can sometimes help with ink flow issues.
5. Contact Professional Support: If none of the above steps work, it may be a more complex hardware issue. Contact Epson support or other printer repair professionals for further assistance. They might be able to provide specific instructions or determine if your printer needs service.

If you can provide a video of the issue, it might help diagnose the problem more accurately. Feel free to share it, and I'll take a look to see if there's anything more specific that can be done.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility at BCH Technologies Printer Repair Service. Given the high demand, we operate on a first-come, first-served basis, so it might take a few weeks before we can get your printer to drop it off or mail it to us. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed if you opt for mail-in or local drop-off services. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage. Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.

Thank you again for reaching out, and we appreciate your continued support. If you have any more questions or need further assistance, feel free to contact us.
