Frequently Asked Questions
What is the difference between Toshiba CA4W and CE4M?
The CA4W has 318 nozzles at up to 1200 dpi with a 6–90 pl drop range — designed for high-resolution UV applications including Océ Arizona, Fujifilm Acuity, and EFI Rastek printers. The CE4M has 636 nozzles at up to 300 dpi with a 5–35 pl range — designed for Galaxy UD, HAE UV, and Icontek printers. Both support 16-level greyscale but are not interchangeable.
What is the dual ink inlet system on the CA4W?
The CA4W has two ink inlet ports, which can be configured for dual-channel ink supply or converted to a single inlet system depending on the printer's ink delivery design. The configuration required depends on your specific printer model — contact our team to confirm the correct setup before installation.
What does the integrated water channel do?
The CA4W includes an internal water channel for temperature regulation. UV and oil-based inks are viscosity-sensitive — maintaining consistent head temperature ensures stable drop formation and consistent output across long production runs. The complete sealing design prevents contamination from the cooling circuit.
Is the CA4W compatible with Océ Arizona series printers?
Yes — the CA4W is compatible with multiple Océ Arizona models including the 300 GT, 318 GL, 350 GT, 350 XT, 360 GT, and 360 XT. Contact our team with your specific Arizona serial number to confirm before ordering.
Do you ship Toshiba CA4W printheads to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Our Miami location is ideal for Latin American industrial UV print shops using freight forwarders in the Doral area.
