Summary: The Konica 512i Series is an industrial piezo drop-on-demand printhead platform built on an independent driving system, delivering up to three times the driving speed of the traditional KM512 series. Designed for high-productivity industrial inkjet systems, the KM512i LNB stands out with its 30 pl large droplet size and 27 kHz firing frequency, making it a proven solution for high-coverage, high-speed applications such as wide-format graphics, industrial labeling, and ceramic printing.
1. Understanding the Konica 512i Platform
Developed by Konica Minolta, the KM512i platform represents a major upgrade from the conventional KM512 series, primarily through its advanced driving architecture.
Independent Driving System
Unlike the earlier triple-cycle driving system used in the KM512 series, the 512i adopts independent nozzle driving.
This means:
- Each nozzle channel is independently controlled
- Faster response time
- More precise waveform tuning
- Greater stability at high frequencies
Under comparable conditions, the 512i achieves approximately three times the driving speed of the traditional KM512 models, significantly increasing overall printer productivity.
High-Frequency Industrial Performance
Depending on the model, the KM512i series supports firing frequencies of up to 60 kHz.
Higher driving speed enables:
- Increased production throughput
- Stable continuous operation
- Suitability for large-scale industrial manufacturing
It is widely used in:
- Ceramic tile printing
- Industrial label printing
- UV flatbed systems
- Packaging pre-printing
- PCB inkjet applications
Durable Structure with Built-In Heating
The KM512i series features:
- High-durability nozzle construction
- Optimized internal ink flow path
- Integrated heater
This ensures stable jetting performance even with high-viscosity inks such as ceramic inks.
Compact and Lightweight Design
- Dimensions: 131 × 18 × 94 mm
- Weight: Approx. 150 g
- Print width: 72 mm
Its slim body design supports multi-head array configurations and compact industrial printer development.
