$1,726.00
Original Kyocera KJ4B-QA06NTB aqueous piezo inkjet printhead for high-speed water-based ink applications. Features native 600 × 600 dpi resolution, 2,656 nozzles across a 108.25 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, suitable for industrial textile, document, commercial and high-speed aqueous printing systems.
The Kyocera KJ4B-QA06NTB is an original genuine industrial piezo inkjet printhead belonging to the KJ4B-QA series. It is engineered for high-speed printing with water-based (aqueous) inks, including dye, pigment and specialised formulations such as MICR. The printhead incorporates internal filters that prevent foreign particles from reaching the nozzle plate and an integrated reservoir heater with thermistor for precise temperature control and stable jetting performance under varying environmental conditions.
This model delivers native 600 × 600 dpi resolution across an effective print width of 108.25 mm. It utilises 2,656 nozzles (approximately 2,558 active within the effective print area) arranged at a nozzle pitch of 0.042 mm. Maximum drive frequency is 30 kHz, supporting a maximum print speed of 76.2 m/min (commonly stated as 75 m/min). Drop volumes are selectable at 5 pL, 7 pL, 12 pL and 18 pL (18 pL limited to lower drive frequencies). Recommended ink viscosity range is 5.0–6.0 mPa·s. Typical physical dimensions are 200 × 25 × 57.9–59.3 mm (W × D × H) with a dry weight of approximately 420 g. The head does not incorporate nozzle recirculation.
Variant Note
The KJ4B-QA06NTB designation covers a family of hardware variants distinguished by additional suffixes (e.g., -HZ5V-4A, -MS6V-4B, -STDC-4B). These variants differ in electrical interface, connector or OEM-specific configuration and are not interchangeable. Confirm the exact full part number 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 and transactional printing, commercial printing, MICR security printing and other industrial systems requiring reliable 600 dpi performance.
Compatibility Notes
Used in selected industrial systems designed for the KJ4B-QA06NTB family (examples include certain EFI Reggiani, MS Italy, Xerox Rialto 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 the 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 printhead. Proper system integration, approved aqueous inks and correct handling procedures are essential for optimal performance and service life.
