InkBags provides independent printhead repair for the Trimatt ColourStar AQ. Australian-built short-run packaging press family — the ColourStar AQ V and AQ LT run the HP FI-1000 engine, printing boxes, kraft bags and cotton totes 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.
Trimatt ColourStar AQ printhead specification
Parts and recovery procedures do not transfer between printhead families, even when both are HP thermal inkjet — so the engine inside the machine is the first thing to establish.

What printhead failure looks like on a ColourStar AQ
- A white stripe down every box or bag in the run — the dead-sector signature of a fixed page-wide head.
- Nozzle dropout that starts after a job on cotton totes — textile lint settling on the nozzle plate and bridging nozzles.
- Fresh scoring on the nozzle plate after a run on tall or lifting packaging — the head was set too low and made contact with the substrate.
- A colour missing after the machine has stood between short runs — dried ink in a shop that prints on demand rather than continuously.
- Density falling off across the width on long kraft or corrugated runs — paper dust loading the wiper and capping station.
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.
How we approach a ColourStar AQ printhead
The ColourStar is bought for short-run, on-demand work, so the machine stands still more than it runs. That shifts the failure profile: dried ink and cap-down discipline matter more here than wear, and a large share of “dead head” calls on this class of machine turn out to be recoverable blockage.
Head clearance is adjustable because the machine prints on three-dimensional packaging. That same flexibility is the main source of physical head damage we see — a strike on a tall or lifting pack scores the nozzle plate, and scoring is the one failure mode that nothing recovers. If the fault appeared right after a job on a new pack format, say so when you send the nozzle test.
Cotton tote printing puts textile lint into the head area, and lint behaves differently from paper dust — it bridges nozzles rather than abrading the plate. On a machine that runs cotton, service covers the capping and wiping station, not just a flush.
Trimatt publishes the HP FI-1000 engine for the ColourStar AQ V and AQ LT. It has not published the engine for the ultrawide BoxPro, so we identify the head from the machine before quoting rather than assuming the family carries across.
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, matched to the failure mode.
Ink system service
Capping, wiping and supply-side inspection — the parts that usually caused the failure in the first place.
Replacement printheads are available where recovery is not viable, along with original and compatible ink, so a machine that cannot be recovered does not sit idle waiting on a separate supplier.
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.
Trimatt ColourStar AQ printhead repair FAQ
Does the Trimatt ColourStar use an HP printhead?
Yes. HP itself lists Trimatt Systems among the machine builders using the FI-1000 print engine, and Trimatt states the HP Fi1000 engine for the ColourStar AQ V and the entry-level AQ LT — the same 297 mm fixed page-wide head used by other single-pass packaging presses. FI-1000 repair procedures, replacement heads and pigment ink apply to them directly.
Is the ColourStar BoxPro the same printhead?
Trimatt has not published the engine for the ultrawide BoxPro, and its quoted print width is far wider than a single FI-1000 swath, so we do not assume it is the same. Send a photo of the head assembly or the part number and we confirm what is inside before quoting.
We print cotton tote bags and keep losing nozzles. Is the head failing?
Usually not. Textile lint settles on the nozzle plate and bridges nozzles, and it comes straight back if only the head is flushed. On a machine running cotton, the capping and wiping station is part of the job.
We are in Australia — can InkBags still help?
Yes. In most cases only the printhead assembly ships, not the machine. Tell us the model and we confirm what has to come out and how to pack it so the head is not damaged in transit.
Can InkBags supply ink for a ColourStar?
Yes — original HP pigment ink and our own compatible pigment equivalent for FI-1000 based machines. Pricing is quoted per request through the ink page.
Can the Trimatt ColourStar AQ printhead be repaired or does it need replacing?
Both happen. Blockage, dried ink, contamination and air-lock recover in a large share of cases; electrical or physical damage to the die does not. The nozzle test print tells the two apart before any money is spent.
How much does Trimatt ColourStar AQ printhead repair cost?
It is quoted per case, because the cost depends on the failure mode and on whether the ink delivery system also needs service. Send the nozzle test and you get a scope and a price up front.
