What to know about compatible cartridges
Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Choosing compatible W1143A reload kits substantially reduces printing costs per page while maintaining smooth toner injection into your Neverstop printer. Read our guide comparing genuine vs compatible cartridges to evaluate performance and savings for your office setup.

Pro Tip
Always check that your Neverstop printer toner indicator shows fewer than two bars before attempting to inject a 143A reload kit; the mechanical reload port locks automatically until the internal reservoir has sufficient capacity to take a full 2,500-page payload.
Frequently Asked Questions
Can I inject a 143A reload kit when the printer shows half full?
No, the physical reload plunger on HP Neverstop printers is mechanically locked until the internal toner memory drops below a specific threshold (typically 1 bar remaining) to prevent overfilling and spillage.
Does the 143A kit replace the imaging drum assembly?
No, the 143A W1143A is a toner reload kit that injects raw toner into the permanent internal drum unit (HP 144A), which typically lasts up to 20,000 pages before needing replacement.
Why does the dual pack (W1143AD) require two separate injection steps?
The W1143AD dual pack contains two individual 2,500-page plunger barrels. You must inject one full barrel, wait for the printer to process the level change, and inject the second barrel only when the reservoir capacity allows.
