Boxmaking Machinery GmbH BM300 printhead repair and nozzle recovery
Single-pass packaging press built directly around the HP FI-1000, printing bags, boxes, mailers and envelopes at up to 27 m/min.
Boxmaking Machinery GmbH BM300 — printhead and engine specification
Knowing exactly which engine is inside the machine matters: parts and recovery procedures do not transfer between printhead families, even when both are HP thermal inkjet.

What 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.
How we approach a BM300 printhead
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.
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.
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.
What the service covers
Diagnosis
Failure-mode identification from the nozzle test print, plus a straight answer on whether recovery is realistic.
Nozzle recovery
Deep flushing of the ink path and restoration of blocked nozzle areas, using procedures matched to the failure mode.
Ink system service
Capping, wiping and supply-side inspection — the parts that usually caused the head failure in the first place.
Parts and ink
Replacement printheads where recovery is not viable, plus original and compatible ink so the machine can go straight 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. Send the nozzle test and you get a scope and a price before anything is dismantled.
Boxmaking Machinery GmbH BM300 printhead 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.
