$1,486.00
Original Kyocera KJ4B-0300 aqueous piezo inkjet printhead designed as a dual-color unit for high-speed industrial textile and single-pass applications. Features 300 × 600 dpi resolution, 2,656 nozzles (1,328 × 2 channels) across a 112.35 mm effective print width, variable drop volumes of 5–18 pL, maximum drive frequency of 30 kHz and print speeds up to 76.2 m/min (higher in optimized single-pass configurations), ideal for textile, document and industrial aqueous printing systems.
The Kyocera KJ4B-0300 is an original genuine industrial piezo inkjet printhead from the KJ4B series. It is a dual-color (two-channel) model engineered for high-speed printing with water-based (aqueous) inks. The head integrates two independent ink channels within a single unit, enabling efficient multi-color configurations while reducing the total number of printheads required in industrial systems. It is widely used in both single-pass and multi-pass textile, document and industrial printing applications.
The printhead delivers a native resolution of 300 × 600 dpi across an effective print width of 112.35 mm. It utilises 2,656 nozzles arranged as 1,328 nozzles per channel. Maximum drive frequency is 30 kHz. Official maximum print speed is 76.2 m/min; certain single-pass configurations report higher linear speeds up to approximately 120–152 m/min depending on system design and waveform. Drop volumes are selectable at 5 pL, 7 pL, 12 pL and 18 pL (18 pL limited to drive frequencies of 20 kHz or lower). Recommended ink viscosity range is 5.0–6.0 mPa·s. Physical dimensions are 200 × 36 × 68.5 mm (W × D × H) with a dry weight of approximately 540 g. The head does not incorporate nozzle recirculation and is typically equipped with internal filters and temperature control features consistent with the KJ4B series.
Variant Note
The KJ4B-0300 is available in multiple hardware variants (Standard, MS-specific, DGI-specific and others). These variants differ in electrical interface and cable configuration and are not interchangeable. Confirm the exact variant required by your printer system before ordering. Replacement of the associated flexible head cables is strongly recommended when installing a new printhead.

Applications
High-speed single-pass and multi-pass aqueous printing for industrial textile production, document printing, transaction printing and other industrial systems requiring dual-color 300 dpi performance with high productivity.
Compatibility Notes
Used in selected industrial systems designed for the KJ4B-0300 (examples include certain MS Italy, Printerevolution, FabriVu, Hanway, EFI Reggiani BLAZE, HOMER and other OEM platforms). Exact variant matching is critical. Full system-level compatibility (head interface board, waveform, drive voltage, cables, firmware and ink delivery system) must be confirmed with the printer manufacturer or system integrator prior to installation. Physical dimensions alone do not guarantee electrical or fluidic compatibility.
Operational Recommendations
- Always handle the printhead while wearing a grounded anti-static ESD wrist strap.
- Power down the complete system before connecting or disconnecting any flexible cables.
- Thoroughly flush both ink channels with an approved cleaning solution before first use or after prolonged storage.
- Use only aqueous inks within the recommended viscosity range of 5.0–6.0 mPa·s.
- Replace the associated head cables at the same time as the printhead to minimise connection-related issues.
Warranty
Store Warranty: 30 Business Days After Delivery. Eligible claims for damage on arrival, defective product, non-functioning product, incorrect item or missing components require: (1) a continuous uninterrupted unboxing video, (2) clear evidence of the shipping package and shipping label, (3) clear evidence of the product condition, and (4) for functionality claims, a video showing initial installation and operation performed by a qualified technician. All claims remain subject to verification. When approved, a 100% money-back refund without deduction is provided. Manufacturer Warranty: Not publicly specified by Kyocera in available documentation. Warranty expressly excludes defects related to the use of non-original inks, clogged/missing/deviated nozzles, misuse, abuse, neglect, improper storage, lack of prescribed maintenance, operation for unintended purposes, third-party applications/software/parts/components or bulk ink systems, and purely cosmetic issues.
This is a genuine original Kyocera OEM dual-color printhead. Proper variant selection, system integration, approved aqueous inks and correct handling procedures are essential for optimal performance and service life.
