Before ordering a CIJ deflector plate, verify the exact installed reference, printhead revision, electrode geometry, mounting interface, electrical connection details and supplied hardware. A photo alone is not enough when several versions look similar.
What a CIJ deflector plate does
A deflector plate is part of the printhead assembly that helps direct charged droplets after the break-up point. Its physical geometry and electrical interface must match the installed printhead version. This article is procurement guidance, not an installation procedure.
Six checks before ordering
1. Exact installed reference
Record every part number, revision mark and stamped identifier visible on the removed part. Send clear photos of both faces and any attached label.
2. Printer and printhead revision
State the printer model and the printhead revision. A component intended for one revision should not be assumed to fit another.
3. Plate and electrode geometry
Compare the number of plates or electrodes, their spacing, length, profile and orientation. Do not decide from the general outline in a catalogue photo.
4. Mounting interface
Check fixing-hole positions, fastener type, locating features and the relationship to the surrounding printhead parts.
5. Electrical connection and insulation
Confirm terminal style, lead direction, connector details and any insulating pieces. Include a close photo of these details in the enquiry.
6. Supply scope
Confirm whether the offer covers one plate, a matched set, leads, insulation, seals or mounting hardware. Order the scope required for your planned service work.
Information to send for a compatibility check
| Item | Why it matters |
|---|---|
| Printer model and printhead revision | Helps narrow the applicable mechanical layout. |
| Installed reference and markings | Identifies the version more reliably than appearance alone. |
| Photos of both sides and connectors | Lets the supplier compare geometry and interfaces. |
| Required quantity and supply scope | Clarifies whether a single item or a complete set is needed. |
Receiving check before service work
- Compare the received reference and visible geometry with the existing part.
- Check the terminal and lead orientation before opening the printhead assembly.
- Confirm the supplied hardware and insulation pieces against the quoted scope.
- Keep the packaging label and receiving photos with the maintenance record.
For a broader checklist, see our CIJ spare-part compatibility guide and the compatibility and ordering guide.
Frequently asked questions
Can I order from a photo of the deflector plate?
A photo is useful, but it should be paired with the installed reference, printer model, printhead revision and connector views before compatibility is checked.
Should I order one plate or a set?
Confirm the planned service scope and the seller’s supply description. Do not assume that a listing for a plate includes matching parts or hardware.
What should I include in an enquiry?
Send the printer model, printhead revision, installed reference, clear photos of both sides, quantity and delivery country. This gives the supplier the details needed to check the proposed item.
