HP FI-1000 printhead repair
The 297 mm HP Fixed Imager 1000 printhead itself — the part that fails in every FI-1000 based machine, whatever badge is on the front.

Printware iJetColor Pro PXG printhead repair & nozzle recovery
InkBags repairs the printhead in the Printware iJetColor Pro PXG. Packaging-oriented member of the iJetColor Pro series using the HP FI-1000 fixed imager, launched at PackExpo 2021. Recovery is realistic when the fault is dried ink, blockage, contamination or air-lock; it is not when a die segment is electrically dead or the nozzle plate is damaged. Send a nozzle test print and we tell you which one you have — before quoting.
Printware iJetColor Pro PXG — engine and printhead specification
The engine inside the machine is the first thing to establish: parts and recovery procedures do not transfer between printhead families, even when both are HP thermal inkjet.

What printhead failure looks like on a iJetColor Pro PXG
- Sector loss showing on every piece across a packaging run.
- Nozzle plate contamination from coated and specialty packaging substrates.
- Colour drift on a single channel after a substrate change.
- Recovery cycles restoring nozzles only briefly before they drop out again.
Photograph the nozzle test print before running any more recovery cycles. Repeated aggressive purging on a head that has already dried out can turn a recoverable fault into a replacement.
Symptom, cause, and whether it recovers
The pattern on the nozzle test print is what separates a cleanable head from a dead one. This is the table we work from — the same one for every HP FI-1000 machine.
| What you see | What it usually means | Outcome |
|---|---|---|
| A solid white band down the web, in the same place on every copy | A whole die segment has stopped firing | Sometimes recoverable — recovers if the cause is dried ink or blockage, not if the segment is electrically dead |
| Fine missing lines that partly return after a purge | Nozzles blocked by dried ink after idle time | Recoverable |
| Nozzles recover, then drop out again within a short run | Restriction upstream of the head — filter, line or supply pressure | Recoverable — replacing the head would not have fixed it |
| One colour channel weak or missing | Blocked feed or partially blocked die area on that channel | Recoverable |
| Density falling off across the width after long production | Nozzle plate contamination, worn wiper or failing capping | Recoverable — the capping and wiping station has to be serviced too |
| Head errors or refusal to come ready after running dry | Air drawn into the head during an ink starvation event | Recoverable — controlled purging and re-priming |
| Scratches or visible damage on the nozzle plate | Physical contact damage | Replacement head |
How we approach a iJetColor Pro PXG printhead
Note 01
The PXG runs a wider variety of substrates than the envelope-focused 1175P, so we ask what was on the machine when the fault appeared — coating transfer from specialty stock is a distinct failure mode from ordinary drying.
Note 02
Nozzles that recover after a purge and then drop out again within a short run point at a supply-side restriction rather than at the head, and we test the ink path accordingly before quoting head work.
Note 03
Because the PXG shares the FI-1000 engine with the rest of the family, parts and recovery procedures are common — what differs is the contamination profile from packaging substrates.
How a repair job runs
Send a nozzle test print
Photograph or scan the nozzle test and describe what the machine was doing when the fault appeared. Do not keep running recovery cycles first — repeated aggressive purging on a head that has already dried out can turn a recoverable fault into a replacement.
Get a diagnosis
We identify the failure pattern — sector, row or random dropout — and tell you whether recovery is realistic, before anything is dismantled.
Approve scope and price
You get the work scope and the price up front, including whether the ink delivery system needs service as well. No open-ended billing.
Service, or replace
We recover the head where it can be recovered and supply a replacement where it cannot. Either way the machine goes back into production.
Pricing and turnaround are quoted per case, because both depend on the failure mode and on whether the ink delivery system needs work as well. Replacement heads and original or compatible ink are available where recovery is not viable, so a machine that cannot be recovered does not sit idle waiting on a second supplier.
Printware iJetColor Pro PXG printhead repair FAQ
Nozzles come back after a purge and then fail again. Is the head faulty?
Often not. Nozzles that recover and then re-fail within a short run usually indicate a restriction upstream of the head — a filter, a line, or a supply pressure problem — rather than head damage. Replacing the head in that situation does not fix the fault.
Do you also supply pigment ink for the PXG?
Yes, both original HP and our compatible pigment ink for FI-1000 machines. Volumes and pricing on request.
