To resolve this, I would recommend performing a ***Power Cleaning***. Power cleaning is an advanced cleaning process that forces more ink through the printhead nozzles, helping to clear any blockages that could be affecting your print quality.
=== Steps to Perform Power Cleaning on Your Epson Printer: ===
# ***Turn on your printer*** and make sure it is connected to your computer.
# Open the ***printer settings*** on your computer or the printer's control panel.
# Go to ***Maintenance*** (or ***Printer Utility*** depending on your model).
# Select ***Power Cleaning*** from the available options.
# Follow the on-screen prompts to complete the process.
