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.

Boxmaking Machinery BM300 printhead repair & nozzle recovery
InkBags repairs the printhead in the Boxmaking Machinery BM300. Single-pass packaging press built directly around the HP FI-1000, printing bags, boxes, mailers and envelopes at up to 27 m/min. 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.
Boxmaking Machinery BM300 — 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 BM300
- White stripe down the length of a run of bags or boxes — the classic dead-sector signature on a fixed head.
- Paper dust and fibre from cardboard substrates loading the wiper and capping station, then transferring back onto the nozzle plate.
- Density loss on one channel after the machine has stood over a weekend without a proper cap-down.
- Ink starvation when running long, heavy-coverage jobs on absorbent kraft board.
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 BM300 printhead
Note 01
The BM300 runs uncoated, dusty substrates — kraft board and paper bags — so the dominant failure driver on this machine is abrasive fibre contamination of the nozzle plate, not ink chemistry. Service therefore always includes the wiper and cap assembly, not just the head.
Note 02
Because the BM300 prints the full 297 mm in one pass at up to 27 m/min, a partially blocked die shows up as a visible defect on every single piece — there is no second pass to mask it.
Note 03
We check the ink supply path end to end on this machine: on heavy-coverage packaging work, starvation at speed damages heads that were otherwise healthy.
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.
Boxmaking Machinery BM300 printhead repair FAQ
My BM300 prints a white line down every bag. Is the head dead?
Not necessarily. On the BM300 the most common cause is fibre and paper dust contamination on the nozzle plate plus a wiper that is no longer cleaning properly — that is recoverable. A genuinely dead die segment is also possible. A nozzle test print tells the two apart.
Do you service the BM300 ink system as well as the printhead?
Yes. On a dusty-substrate machine like the BM300, servicing the head without servicing the capping, wiping and ink supply usually means the same fault returns within weeks.
Can InkBags supply ink for the BM300?
Yes — both original HP pigment ink and our compatible pigment ink for FI-1000 based machines. See the ink page for the request form.
