Chips and Firmware: Why Some Printers Reject Third-Party Cartridges

Almost every modern toner and ink cartridge carries a small chip. It tells the printer what the cartridge is — its colour and its rated yield — and lets the machine estimate remaining levels. That is genuinely useful. But the chip is also a gate: the printer’s firmware reads it and decides whether to accept the cartridge. When a manufacturer ships a firmware update that tightens those checks, a consumable the printer happily used yesterday can suddenly return a “non-genuine” or “cartridge problem” warning. This is not a myth. HP’s “Dynamic Security”, introduced in 2016, is the most documented example; in March 2025 HP settled a US class action over firmware that had rendered third-party cartridges incompatible, agreeing to keep giving users the option to install or decline updates that include Dynamic Security.

It is worth being precise about what “chip compatibility” means, because two very different things get confused. A legitimate compatible or remanufactured cartridge uses its own, independently produced chip that communicates with the printer correctly and reports honestly the cartridge it is actually fitted to. That is lawful, and it is what Ergonet supplies. It is a completely separate matter from illegal “clones” that copy a manufacturer’s patented design — the goods that are seized at EU borders. Buying first-quality compatibles from a serious supplier and buying an infringing counterfeit are not the same act, even if both sit in a printer’s cartridge bay.

So how does a serious supplier keep compatibles working? By treating the chip as an engineering problem, not an afterthought: sourcing consumables whose chips are kept current against new firmware, tracking which printer models and firmware revisions have changed behaviour, and advising customers plainly — for instance, that automatic firmware updates can be reviewed rather than blindly accepted on fleets that run compatibles. As both an authorised reseller of OEM brands and a supplier of first-quality compatible and remanufactured consumables, Ergonet’s role is to give you an informed choice and the after-sales service to back it, on original and compatible alike — not to pretend the firmware question does not exist.
