Konica KM1024i SAE-C Printhead

The Konica KM1024i SAE-C Printhead is a high-speed piezo drop-on-demand inkjet printhead designed for water-based inks. It features 1024 nozzles arranged in 4 lines of 256 nozzles each, with a resolution of 360 npi (90 npi x 4 lines). The droplet size is 6 picoliters, and it can operate at a maximum firing frequency of 43-45 kHz. The print width is 72 mm.

Konica KM1024i SAE-C Printhead - Quick Facts

•     Core purpose: 1024-nozzle piezoelectric printhead designed for water-based inks in industrial and wide-format printing applications.
•     Configuration: 4 rows of 256 nozzles (1024 total); 72 mm print width; four-line arrangement for high nozzle density and improved alignment.
•     Drop size option: typically offered in the 6 pL category (SHE/SAE-C variants commonly use 6 pL); check exact model labeling to confirm drop volume.
•     Drive system: independent drive system; all nozzles fire simultaneously, enabling consistent footprint and faster data processing.
•     Firing frequency: around mid-40 kHz range (e.g., ~43–56 kHz depending on variant); confirm the exact specification for your chosen SKU.
•     Ink compatibility: designed for water-based inks; some KM1024i variants may also support UV/solvent in specific configurations, so verify ink compatibility with your intended chemistry.
•     Integrated heater: many KM1024i variants include an internal heater; essential for maintaining ink viscosity and ensuring consistent droplet formation in varying ambient conditions.
•     Grey-scale: typically 8 levels; affects tonal range and color gradation.
•     Physical footprint: compact printhead housing suitable for compact printhead assemblies; confirm connector type and cable length for your printer.
•     Replacement and maintenance: routine cleaning (self-checks, factory cleaning fluids, ultrasonic cleaners) recommended; follow vendor-approved maintenance intervals to sustain performance.
•     Typical applications: signage, posters, packaging prototypes, textiles (with appropriate inks), and any aqueous-print workflows requiring high nozzle density.
•     Compatibility checks: verify exact model tag (KM1024i SAE-C vs MAE-C vs SHE variants) to ensure:

        Drop size and nozzle arrangement align with your printer’s drive electronics and firmware

        Ink compatibility matches your ink system (water-based only or others)

        Mechanical fit (nozzle pitch, connector type, mounting) with your printhead carrier

•     Electrical and data: ensure your controller’s waveform, current drive, and timing can drive 1024-nozzle heads; improper drive parameters can degrade print quality or damage the head.
•     Warranty and sourcing: new vs refurbished options available; warranty terms vary by seller; verify return policy, supported ink chemistries, and compatibility with your printer model.
•     Training and support: We often provide installation guides, waveform templates, and cleaning solution recommendations; consider including technical support or service contracts in your purchase.

Evaluation checklist (quick decision guide)

•     Are you using water-based inks? If yes, KM1024i SAE-C is generally suitable; confirm exact compatibility with your ink supplier.
•     Do you require 6 pl droplets with 4×256 nozzle banks? This aligns with SAE-C/SHE-type variants; confirm the exact variant in your quote.
•     Is 72 mm print width acceptable for your print engine geometry? Ensure your carriage and media path can accommodate this width.
•     Do you have compatible drive electronics and firmware? Independent drive systems require matching waveform and timing; confirm with your printer manufacturer or integrator.
•     What’s the total cost of ownership? Include head price, potential mounting hardware, cables, cleaning supplies, and any required service contracts.

Illustrative considerations

•     If upgrading from 512-nozzle or older KM1024 variants, expect improved print quality at high speed due to simultaneous firing and higher nozzle density.
•     For textile or signage lines that demand sharp edges, ensure your printhead alignment and calibration routines are compatible with the 4-line, 256-nozzle per line arrangement.
