What are firmware updates?
Firmware updates are updates put through your printer by the manufacturer. Sometimes these updates can include changes that prevent third-party cartridges from working. In most cases you can’t undo an update, but you can often switch automatic updates off to help prevent this.
Will the cartridges display toner levels?
In most cases, yes. These cartridges are designed to work like originals so the same functions should be available. If your printer firmware changes how it reports levels, the cartridges will still print normally.
The cartridges look different to the originals — will they fit?
Compatible cartridges may look slightly different due to legal design requirements, but they are made to fit your printer and are tested rigorously to ensure compatibility and performance.
Troubleshooting: “Cartridge not recognised” or colour issues
Install one cartridge at a time, ensure all protective seals have been removed, and power the printer off/on. Allow calibration to complete. If issues started after a firmware update, contact us for help or a quick replacement.
