Toshiba TEC CA4 Original Industrial Inkjet Printhead 6-90pL 16-Level Greyscale

The Toshiba TEC CA4 is an original industrial inkjet printhead based on multi-drop grayscale micro-piezo (drop-on-demand piezoelectric) technology, engineered for high-quality industrial printing applications. This printhead belongs to the earlier generation of the Toshiba TEC CA series and shares the nozzle-row architecture of the Xaar 318 heritage platform, delivering 318 active nozzles in a single-row configuration.

With multi-drop jetting capability, each dot can be formed from a minimum drop volume of 6 picolitres up to a maximum of 90 picolitres (up to 15 drops), enabling 16 levels of greyscale. This technology produces smoother colour gradation compared with conventional binary printheads, making it well suited for signage, UV flatbed, and industrial graphics applications that demand high visual quality.

The CA4 is compatible with oil-based pigment inks and UV-curable pigment inks. Thermal control via water circulation (on related variants) helps maintain consistent ink viscosity during extended print runs. This printhead is widely used as a genuine OEM replacement spare part on entry- to mid-level UV flatbed systems, particularly the Océ Arizona 300/350 series and Fujifilm Acuity Advance range.

As an official replacement component, the Toshiba TEC CA4 ensures physical, electrical, and jetting-performance compatibility with the printer manufacturer’s specifications, making it the standard choice for technicians and purchasing departments in B2B industrial printing environments.

Note: CA4, CA4W and CA4NW are functionally equivalent for most Arizona 300/350 applications. The main differences concern water-channel configuration and sealing revisions. Values unavailable after research are marked “Not publicly specified”.

Technical Precision & Operational Advisory

• ESD Protection: Always use a grounded wrist strap and anti-static surface when opening the packaging and handling the printhead. Piezo printheads are highly sensitive to electrostatic discharge.
• Power Isolation: Completely power down and isolate the printer before removing or installing the printhead. Do not hot-swap.
• Ink Compatibility: Use only oil-based pigment or UV-curable pigment inks that have been verified for compatibility. Incompatible inks can damage nozzles and internal channels.
• Filtration & Contamination: Ensure the ink filtration system is functional and free of contaminants before installation. Particle contamination is a primary cause of nozzle dropout.
• Meniscus & Pressure: Set meniscus pressure and sub-atmospheric pressure according to the printer specifications. Incorrect pressure leads to misfiring or air ingestion.
• Thermal Control: On systems that support water circulation, ensure the cooling circuit is connected and flow is stable to maintain ink viscosity.
• Orientation & Mounting: Install the printhead with the correct orientation and alignment using the recommended jig tool (e.g. PPHDI11519 for Océ brackets). The original bracket can normally be reused.
• Handling Factory-Sealed Unit: Do not break the seal until ready for installation. Once the printhead has been exposed to ink or installed, it is considered used and cannot be returned.
• Drive Electronics: Confirm that the waveform and drive voltage (14–31 V) match the printer configuration. Operation outside the specified voltage range can shorten printhead life.

Compatible Models & Systems

The list below is compiled from cross-verified industrial sources. Only models with credible evidence are included.

Note: Exact compatibility must be confirmed against the printer part number and carriage configuration before ordering. Some sources mention Arizona 200/250 GT models; independent evidence for those models is limited and they are therefore not listed as confirmed.

Terms, Warranty & Customer Protection

Pre-Installation Guarantee: 100% brand-new, factory-original product. Each unit is inspected and sealed before shipment. We guarantee authenticity and factory condition upon arrival.

Store Warranty Policy: 30 working days warranty covering manufacturing defects. Warranty claims require complete unboxing video and professional installation video performed by an experienced technician following standard recommended procedures.

Final Sale Conditions: Once the printhead has been exposed to ink or installed into a printer, it is considered used and cannot be returned or exchanged. Please verify compatibility and installation readiness before opening the sealed packaging.
