The Epson L850, PX660, and L805, which are available in Kenya all use a 6-color Micro Piezo inkjet printhead with a high resolution of 5760 x 1440 dpi, and the printheads are generally interchangeable across these models (part number F180040).
Printhead Specifications Overview
The printheads for the Epson L850, PX660, and L805 share the following core specifications:
Printing Method: On-demand inkjet (Piezoelectric), also known as Epson Micro Piezo print head technology.
Nozzle Configuration: 90 nozzles for black and 90 nozzles per color, for a total of 540 nozzles (90 x 6).
Number of Colors: 6 colors (Black, Cyan, Light Cyan, Yellow, Magenta, Light Magenta).
Minimum Droplet Size: 1.5 picolitres (pl), with Variable-Sized Droplet Technology.
Highest Printing Resolution: 5760 x 1440 dpi (optimized).
Ink Compatibility: Primarily designed for dye-based inks, such as the Epson Claria Photographic Ink or the ink used in the EcoTank systems.
Printhead Part Number: F180040 (replaces F180000/F180030).
Printer Model Differences
While the core printhead assembly is the same, the printers themselves have different features and designs, especially concerning their ink systems:
Epson L850 & L805: These are part of the EcoTank series and feature large, integrated, refillable ink tanks (using ink bottles).
Epson PX660: This model is designed to use individual ink cartridges, specifically the Claria ink cartridge system.
Despite the difference in how ink is supplied to the printer, the actual printhead mechanism that fires the ink droplets is the same for all three models, which is why the printhead unit itself is interchangeable.
