What's the typical lifespan of a print head, and does an E05 error always mean it's at the end of its life?

The typical lifespan of a print head can vary greatly depending on usage, ink quality, and maintenance, but it generally ranges from a few years for moderate users to potentially longer. An E05 error doesn't *always* mean the print head is at the absolute end of its life, as it could be a temporary recognition glitch or a simple dirty contact. However, if troubleshooting steps like power cycling, cartridge reinstallation, and cleaning contacts fail, it strongly suggests a permanent print head malfunction that necessitates replacement.
