DX7 F189010 Printhead for Epson B-Series

The DX7 F189010 is a replacement printhead nozzle designed for specific Epson printers. It fits the B300, B308, B310, B318, B500, B508, B510 and B518 models. This part restores printing function when the original head wears out or fails. It is supplied new and ready for installation.

Locked interface limits third-party use

The printhead uses a locked interface that restricts compatibility to the listed Epson B-series models only. Printers outside this range cannot accept the part due to firmware and hardware checks. Buyers needing a head for other Epson series or different brands must source a different component. Compatibility cannot be extended by adapters or software workarounds.
