Technical Specifications

Part Number Supersession Information

FA191140 is the active, direct factory revision from Epson. It supersedes older part numbers including F191040, F191110, F191000, F191010, and F191080. If your maintenance manual, service documentation, or older component is labeled with any of these prior numbers, the F191140 serves as the direct factory replacement with identical mechanical fitment and pin configuration.

Technical Precision & Operational Advisory

• Aqueous Pigment Compatibility: Formulated specifically for Epson aqueous pigment ink systems (UltraChrome HDR/K3). Do not use third-party solvent, UV, or dye-sublimation ink formulations, as non-approved chemistries will destroy the internal piezo elements and degrade the specialized surface coating.

• Head Cable Replacement: Installing new flat flexible head cables (FFC) alongside the printhead is strongly advised. Flexed, contaminated, or worn data cables are a major cause of post-installation communication faults and electrical shorts.

• Damper & Selector Maintenance: Check and replace ink dampers and cleaning cap assemblies to prevent ink starvation and maintain proper vacuum seals during head park cycles.
