Epson SureColor & Stylus Pro MicroPiezo TFP Printhead F191121 (F191151 / F191152)

Product Overview

The Epson MicroPiezo TFP Printhead (Part Codes: F191121 / F191151 / F191152) is a 100% genuine original high-performance replacement printhead engineered for Epson's professional 24-inch and 44-inch SureColor P-Series and Stylus Pro graphic and photo plotters. Built with ink-repelling coating technology and operating at high jetting frequencies up to 50 kHz, this printhead incorporates 360 nozzles per channel (2,880 active nozzles across 8 channels) to output precise variable droplets as small as 3.5 picoliters.

Designed specifically for UltraChrome HD and UltraChrome K3 aqueous pigment ink systems, the F191121 head delivers exceptional tonal depth, color consistency, and smooth grayscale density. It serves as a direct factory replacement part to resolve severe nozzle dropouts, persistent horizontal banding, physical faceplate damage, or internal electronic driver errors.

Technical Specifications

Technical Precision & Operational Advisory

• Aqueous Pigment Inks Only: Built strictly for water-based dye and UltraChrome HD/K3 aqueous pigment inks. Do not run eco-solvent, solvent, DTF, or UV inks through this head, as non-aqueous chemicals will dissolve internal manifold seals and cause immediate internal short-circuits.
• Flat Flexible Cable (FFC) Inspection: Carefully inspect flat ribbon head cables before installation. Any bent contact pins, physical creases, or liquid ink contamination on ribbon ends will cause a direct electrical short-circuit, damaging both the new printhead and the printer head driver board ICs upon powering on.
• Electrostatic Discharge (ESD) Safety: MicroPiezo TFP actuators are sensitive to static electricity. Technicians must wear anti-static grounding wrist straps during installation and ensure the main power cord is completely disconnected before touching internal electronics.
• Capping Station & Wiper Maintenance: Always replace or thoroughly service the wiper blade, anti-drying cap top assembly, and flushing pad when installing a new printhead to maintain proper vacuum seals and prevent nozzle drying.
