Xaar Irix Core 40W Printhead - XP12800072

    The Xaar Irix Core 40W (XP12800072) is a 128‑nozzle, 40 pL drop-volume industrial inkjet printhead designed for solvent/oil/water-based inks and intended as a compact, high‑speed replacement head for many wide‑format and industrial printers.

Technical summary for quick evaluation

•     Nozzles and resolution: 128 active nozzles, nozzle density 185 npi (≈360 dpi physical sampling).
•     Drop volume and velocity: nominal drop size 40 pL, drop velocity ≈6 m/s with drop velocity variation ±0.50 m/s (3σ).
•     Frequency and speed: maximum firing frequency up to ~8.3 kHz and linear print speed about 1.17 m/s at 180 dpi (depends on integration).
•     Physical dimensions and weight: 37.2 × 11.3 × 40.8 mm, weight ≈15.5 g; typical print swathe ≈17 mm; recommended print distance <5 mm.
•     Ink compatibility: compatible with a wide range of oil, solvent and many water‑based ink systems (suitable for coding/marking and functional fluids uses).
•     Reliability / integration notes: marketed as robust and low‑maintenance; typically a direct replacement for discontinued Xaar XP12800007/0009 without firmware changes for many controllers (confirm with your printer vendor).

Buyer comparison checklist (vs common alternatives)

•     Drop size / application: 40 pL is good for moderate detail, text and graphics with reasonable laydown; choose 80 pL/other heads if you need heavier laydown or thicker inks.
•     Speed vs grey control: Irix Core 40W is binary-mode focused with high firing frequency; for more greyscale control or finer photo-like gradients consider greyscale heads (different Xaar families).
•     Ink type: confirm your exact ink chemistry and viscosity (Irix Core works with many solvent/oil inks; check viscosity range and vendor compatibility).
•     Physical fit and electronics: dimensions and connector/pinout must match your carriage and controller; the XP12800072 is often listed as a drop-in for many DGI, Gongzheng, Wit-Color and other machines but verify electrical/mechanical compatibility before purchase.
•     Warranty and exclusions: Manufacture warranties (exclude damage from non‑original inks, clogging from poor maintenance, misuse, or third‑party modifications - factor this into procurement and maintenance plans).

Compatibility examples (common printers listed)

    Reported compatible/practical replacements include models from DGI (XP-2506 series), Gongzheng (GZC/GZY series), Wit‑Color Ultra/3320 series, DGS Color Xpress, and other large‑format/flatbed integrators; always confirm with the printer manufacturer or supplier that XP12800072 is supported for your specific firmware and carriage.

Practical purchasing recommendations

•     Confirm exact part number and insulator color where suppliers differ (some listings note light‑grey or purple insulator variants) and match to your printer’s expected variant.
•     Ask the seller for a compatibility/fit guarantee and a return or DOA policy; request data on nozzle test results and whether the head is new, reconditioned, or compatible clone (many listings show “100% new Original”).
•     If you use non‑original inks or a bulk ink system, confirm that the supplier’s warranty covers your intended use or plan for a preventive maintenance schedule to avoid nozzle clogging (warranty exclusions commonly apply).

One-line purchase decision aid

    Choose XP12800072 (Irix Core 40W) if you need a lightweight, 128‑nozzle, 40 pL head for solvent/oil/water inks with high firing frequency and broad printer compatibility; choose an 80 pL or greyscale head instead when you need heavier ink laydown or finer tonal control
