How do I troubleshoot an 'Error 001' on my Epson L3250?

An 'Error 001' typically signals a problem with the print head. First, try the print head cleaning utility from the printer's control panel or the Epson iPrint app. If that doesn't work, perform a deep cleaning. Ensure all ink tanks are properly installed and not empty. If the issue persists, a print head replacement may be required.
