Do not select decoders by appearance only. Confirm the old decoder/sensor code, printer model, LPI or chip function, connector/cable option, board version and installed position.
Install with the printer powered off. After replacement, check cable direction, encoder strip/sensor gap, ink cartridge or maintenance tank recognition and printer initialization status before production.
What should I confirm before buying?
Send the old part label, printer model, connector photo, installed position and current fault symptom.
Can one decoder fit every printer?
No. Similar H9720/H9730/H9740 sensors or Epson cartridge decoders may use different codes, firmware or printer-series compatibility.
