}Konica KM512 LH 42PL Printhead
Brand: Konica Minolta
Tax excluded. Shipping calculated at checkout
Availability: In stock
The Konica Minolta KM512 LH is a genuine original shear-mode piezo on-demand printhead — the heated large-drop variant of the KM512 series, engineered for oil-based, UV-curable, and solvent ink wide-format printing. With 512 nozzles in 2 rows of 256 at 70.5 µm nozzle spacing, a 36.1 mm print width at 360 dpi native resolution, a fixed 42 pl drop at 7.6 kHz in binary mode, and an integrated heater rated to 55°C — the LH is the correct choice where the printer's ink supply system requires head-level thermal control for UV and oil-based ink viscosity management. Also known as the KM512 LHX. Includes waveform information. Head cable replacement is recommended at installation. Every KM512 LH we sell at Digiprint USA is 100% genuine original Konica Minolta — manufactured in Japan.

Frequently Asked Questions
What is the difference between the KM512 LH and KM512 LN — and how do I know which my printer uses?
The KM512 LH and KM512 LN are both 42 pl, 360 dpi, 512-nozzle binary-mode heads with the same core jetting architecture. The only difference is the integrated heater: the LH has a built-in heater rated to 55°C; the LN does not. The heater allows the LH to bring UV and oil-based inks to their optimal viscosity range directly at the printhead, independent of any external ink temperature system. Printers designed around the LH route ink to the head expecting it to handle thermal management; replacing an LH with an LN in such a system will result in under-heated, overly viscous ink and jetting failure. Check your printer's service manual or contact our team — we confirm LH vs LN from your printer model before shipping.
Why does the KM512 LH have a lower firing frequency (7.6 kHz) than the KM512 LNX-35 (10 kHz)?
The integrated heater in the LH adds thermal mass to the printhead and requires the ink channel to recover slightly longer between firings to maintain stable jetting conditions at elevated temperature. This results in a lower maximum firing frequency of 7.6 kHz versus 10 kHz for the unheated LNX-35. In practical production terms, the difference is modest and is offset by the LH's ability to jet higher-viscosity UV and oil-based inks that the unheated LNX-35 cannot reliably handle without external thermal management. The correct head is determined by your printer's ink type and heating architecture — not by frequency alone.
Is the KM512 LH the same as the KM512 LHX?
Yes — the KM512 LHX is simply an updated designation for the same printhead previously identified as KM512 LH. The core specifications — 512 nozzles, 42 pl, 360 dpi, 7.6 kHz, heater to 55°C — remain identical. Some printer manuals and service documentation continue to reference the original LH designation while newer Konica Minolta documentation uses LHX. At Digiprint USA we ship whichever current designation Konica Minolta ships in genuine OEM packaging.
Do you ship the Konica Minolta KM512 LH to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse before 2PM EST. Our Miami location is ideal for Latin American Gerber Solara, Docan UV, Flora, and Grapo wide-format production shops using freight forwarders in the Doral area.
