Epson I1600 A1 / E1 / U1 Printhead Specifications: Full Technical Data

Official Epson I1600 printhead specs for A1 (aqueous), E1 (eco-solvent), and U1 (UV) models. Includes nozzle count, drop size, viscosity, dimensions, and grayscale performance. Download datasheet.

The Epson I1600 series is a PrecisionCore industrial inkjet printhead built with MEMS technology, offering high reliability, 4-level grayscale, and compact design. It comes in three variants based on ink chemistry—I1600-A1 (aqueous), I1600-E1 (weak solvent), and I1600-U1 (UV)—but shares identical mechanical and electrical architecture.

All data below is sourced directly from Epson’s official documentation.

Integration Notes

Not cross-compatible across ink types: Do not use UV ink in an A1 head, etc.

Requires external ink circulation, filtration (<5 µm), and temperature control.

Electrical interface via FPC cable; driving waveforms are model-specific.

Designed for industrial OEM integration—no built-in electronics.

The Epson I1600 series consists of three non-interchangeable variants, each optimized for a specific ink type. Please verify compatibility with your drive electronics, ink formulation, and thermal management system before selection.
