The printhead is a critical component in inkjet printing systems, responsible for accurately dispensing ink droplets onto the printing substrate. The Ricoh L5160 printhead, used in the Ricoh Pro L5160 wide-format printer, is an industrial-grade inkjet printhead designed to support high-speed and high-resolution printing applications.

The Ricoh L5160 printhead employs piezoelectric inkjet technology, which utilizes electrical signals to deform piezo elements and eject ink droplets without the use of heat. This technology provides precise control over droplet volume, enhances print stability, and extends the operational lifespan of the printhead. As a result, it is suitable for continuous production environments that demand consistent print quality.

The printhead features approximately 1,280 nozzles arranged in multiple rows, enabling high-density ink deposition and improved printing efficiency. It also supports variable droplet (grayscale) printing, allowing the printer to produce smoother color gradations, sharper details, and more accurate image reproduction. The stainless-steel nozzle plate improves resistance to wear and chemical exposure from latex-based inks.

In the Ricoh Pro L5160 printer, multiple printheads are arranged in a staggered configuration to increase printing speed while maintaining precise dot placement and color consistency. This configuration enables the printer to achieve high productivity without compromising image quality.

Overall, the Ricoh L5160 printhead is designed to deliver high durability, precision, and reliability, making it suitable for large-format commercial printing applications such as signage, banners, wallpapers, and graphic displays.
