Brother HL-2460 Toner Cartridges

Unfortunately, most printer manufacturers are known to regionalise their printers. This means that if you purchase a printer in the UK, and move to the US, the US inks will not work in your machine. A UK printer needs inks from the UK. Australian printers need Australian ink etc.

However, you can contact your manufacturer and ask them to change the regionalization of the printer so that it will accept UK sold cartridges.
When contacting them, you'll need a full new set of UK cartridges that are compatible with your printer, as shown above, and access to the Printer and the PC it is connected to.

I hope this is helpful to you.
