Compatible Detection Board for Epson WorkForce

This detection board is a printhead component designed to fit Epson WorkForce models WF-4725, EC-4030, WF-4734, WF-4740 and WF-4270. It serves as a direct replacement part for maintaining printhead alignment and nozzle verification. The board is supplied new and ready for installation in the listed printer models.

Replaces Faulty Printhead Detection Boards

Install this board when the original detection board fails, causing printhead recognition errors or nozzle check failures. The upgrade is worth it when troubleshooting confirms the detection circuitry is the root cause rather than the printhead itself. It is not for printers outside the specified WorkForce series or for resolving issues unrelated to printhead detection.
