}Konica KM512i LNB 30PL Printhead
Brand: Konica Minolta
Tax excluded. Shipping calculated at checkout
Availability: In stock
The Konica Minolta KM512iLNB-30 is a genuine original shear-mode piezo on-demand printhead from the KM512i series — a fundamentally different, higher-performance platform from the original KM512 series. With 512 nozzles in 2 rows of 256 across a 72.2mm print width at 360 dpi, a fixed 30 pl drop in binary mode, an independent drive system enabling simultaneous firing of all nozzles, and a maximum firing frequency of 30.4 kHz — the KM512i LNB-30 delivers more than 4× the throughput potential of the KM512 LH at twice the print width. Solvent ink only; no integrated heater. Includes waveform information for printer integration. Every KM512i LNB-30 we sell at Digiprint USA is 100% genuine original Konica Minolta — manufactured in Japan.

Frequently Asked Questions
What is the difference between the KM512i and the KM512 — and why does it matter when ordering?
The KM512i is a next-generation platform built around an independent nozzle drive system, producing a 72.2mm print width versus the original KM512 series' 36.1mm — exactly double. This wider print swathe allows fewer heads to cover the same carriage width, and the independent drive system allows all 512 nozzles to fire simultaneously at individual addressing, enabling the 30.4 kHz maximum firing frequency — more than 4× higher than the KM512 LH's 7.6 kHz. The original KM512 uses a shared-wall piezo architecture where nozzle groups share actuating walls, limiting independent addressability and frequency. These are not drop-in replacements for each other. Printers designed for KM512i — such as the Allwin C8-512i Plus (note the "i" in the model name) — have carriage dimensions, ink connections, and driver electronics matched to the wider 72.2mm KM512i head. Installing a KM512 (36.1mm) in a KM512i slot will not fit correctly.
Why is the KM512i LNB-30 solvent-only — and can it run eco-solvent or mild solvent inks?
The KM512i LNB-30 has no integrated heater, which means it relies on the ambient and solvent ink's natural viscosity at room temperature — typically well-matched for solvent and eco-solvent formulations. Solvent and eco-solvent inks are engineered to jet reliably without elevated temperature. UV and oil-based inks typically require heat to reach jetting viscosity, which is why the KM512 LH (with its integrated 55°C heater) is specified for those ink types. The KM512i LNB-30 can handle both hard solvent and eco-solvent inks — confirm your specific ink formulation with our team before ordering.
How does 30.4 kHz firing frequency translate to real-world print speed?
Firing frequency is one of three factors determining maximum print speed — alongside carriage speed and resolution mode. At 30.4 kHz with the KM512i's 72.2mm print width, the head can sustain significantly higher linear print speeds than the original KM512 series before drop placement accuracy degrades. In practice, the printer OEM determines actual achievable print speeds based on their carriage mechanics, media handling, and RIP processing. The 30.4 kHz figure means the KM512i LNB-30 is not the bottleneck in high-speed solvent printing systems — unlike the original KM512 heads where the 7.6–10 kHz frequency is often the limiting factor at high carriage speeds.
Do you ship the Konica Minolta KM512i LNB-30 to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse before 2PM EST. Our Miami location is ideal for Latin American Allwin, Sinocolor, and MeiTu wide-format solvent production shops using freight forwarders in the Doral area.
