Konica KM1280iMHH Printhead

Konica Minolta KM1280iMHH is a 450 npi industrial piezo printhead with 1280 nozzles, 10 pl drop size, up to 45 kHz max frequency, 72 mm print width, and support for solvent, UV, and oil inks. It’s positioned as a compact, high-productivity head for industrial single-pass systems, so the buyer decision mainly comes down to ink compatibility, controller compatibility, and maintenance requirements rather than just raw resolution alone.

Buyer FAQ

What is it best for?

The KM1280iMHH is best for industrial printing where you want a compact head, fine drop control, and compatibility with common industrial inks. It is a good fit for coding and marking, packaging, security printing, direct-to-shape, and printed electronics use cases.

What are the key specs?

• The main published specs are 450 npi resolution, 1280 nozzles, 10 pl drop size, 45 kHz max frequency, 72 mm print width, grey scale up to 16 levels, and dimensions of 131 mm x 18 mm x 105 mm with about 185 g weight.
• A third-party product listing also describes it as a 450 dpi, 72.25 mm swathe head with 10 pl drops and 45 kHz max frequency.

What inks does it support?

Konica Minolta lists solvent, UV, and oil inks for the KM1280iMHH. Water-based ink is not listed for this model.

Is it easy to integrate?

It is designed as an industrial piezo head with an independent drive system and a compact body, which helps integration into narrow print modules. Konica Minolta also notes the KM1280i series can support upgrades from KM1024i-based designs with minimal mechanical changes in some cases.

How does it compare with the KM1280iLHH?

The KM1280iMHH uses a 10 pl drop size and higher jetting frequency than the KM1280iLHH, which uses a 19 pl drop size and lower max frequency. In practice, the MHH is the better pick when you want finer detail, while the LHH is the more productivity-oriented option for heavier coverage.

What should I check before buying?

You should verify ink chemistry, required voltage/drive electronics, whether your system is recirculating, your target resolution, and the available maintenance setup. Also confirm the controller and waveform support for this exact head, because industrial heads are sensitive to drive conditions.

What affects head life most?

Konica Minolta says lifetime depends heavily on usage, with nozzle damage from media strike, clogging, and system handling being major factors. Good wiping, capping, and purge maintenance are important for keeping performance stable.

Is there a recommended evaluation path?

Yes. Konica Minolta says the fastest and most efficient way to start is through a head evaluation system, which is the safest way to validate ink, waveform, and print quality before committing to production.

Is there warranty for this products?

Yes. We have manufactured warranty for this printhead.

Purchase checklist

•     Confirm your ink set matches solvent, UV, or oil compatibility.
•     Confirm your controller can drive a piezo head with the required waveform and voltage.
•     Decide whether you need the finer 10 pl MHH or the larger-drop LHH variant.
•     Check available print width, head spacing, and carriage/module constraints.
•     Plan maintenance: wiping, capping, and purge routines.
•     Validate performance with an evaluation system before volume purchase.

Buying verdict

Choose the KM1280iMHH if you want a compact industrial head with finer drop control, moderate-to-high throughput, and broad compatibility with solvent, UV, or oil-based ink systems. Skip it if your application needs water-based ink or if your controller/integration stack is not already designed for industrial piezo printheads.
