Direct answer: Before ordering a CIJ nozzle solenoid-valve assembly, verify the printer family, printhead revision, installed part reference, nozzle specification, valve body, electrical connector, tube routing, fittings and supplied components. A visually similar assembly may not fit or operate correctly.
Why the complete assembly must be identified
A nozzle solenoid-valve assembly combines several interfaces: nozzle, valve, cable, tubing, fittings and mounting points. Compatibility depends on the complete configuration. Stop and isolate the printer according to the manufacturer’s service and safety instructions before inspecting powered, pressurized or ink-wetted parts.
Pre-order verification checklist
| Check | What to record | Why it matters |
|---|---|---|
| Printer and printhead | Manufacturer, full model, series and printhead revision | Assemblies can differ within one family. |
| Installed reference | All readable part numbers and revision markings | The full reference is stronger evidence than appearance. |
| Nozzle specification | The value stated on the installed part or applicable documentation | Do not infer nozzle size from photographs. |
| Electrical interface | Connector, pins, cable length and coil markings | A mechanical match does not confirm electrical compatibility. |
| Fluid interface | Tube count, routing, fittings, ports and tube size | The fluid path must match the installed assembly. |
| Mechanical interface | Bracket, fasteners, orientation and critical dimensions | Small differences may prevent installation. |
| Supplied scope | Nozzle, valve, cable, tubing, fittings and seals included | Listings may include different component sets. |
Photographs to prepare
- Overall installed printhead view
- Close-ups of all labels and references
- Nozzle and valve body from multiple angles
- Connector face and cable exit
- Tube routing, fittings and ports
- Ruler or caliper views for critical dimensions
Use the compatibility and ordering guide. If any reference is incomplete, contact CIJ Printer Parts before ordering.
Real catalog example
The store’s real listing for a compatible 40 µm nozzle solenoid-valve assembly for specified Domino Ax-Series applications shows the interfaces that should be compared. This is an identification example only; appearance does not prove compatibility. Browse Domino-compatible spare parts for related components.
Receiving checks before installation
- Compare the delivered reference and included items with the order.
- Inspect the nozzle, valve, tubing, fittings and connector for transit damage.
- Compare routing, orientation and dimensions with the removed assembly.
- Keep protective caps in place until the approved procedure requires removal.
- Report discrepancies before modifying or installing the part.
Frequently asked questions
Can the printer model alone identify the assembly?
No. Also verify the printhead revision, installed reference, nozzle specification, electrical interface and fluid connections.
Can nozzle size be confirmed from a photograph?
No. Use the installed marking or applicable printer documentation.
Does a print-quality fault prove the assembly is defective?
No. Ink condition, cleaning, pressure, alignment, electronics and other fluid-system components can cause related symptoms. Follow the approved diagnostic procedure.
Are the listed products genuine OEM parts?
Unless explicitly stated otherwise, products are compatible or replacement parts. Manufacturer names identify intended compatibility and do not imply OEM authorization. Visit the CIJ Printer Parts Guides for more guidance.
