Brother printers using the LC123 range of cartridges have already received a number of firmware updates in recent years. Firmware updates are released in order to disable the use of third party or compatible cartridges that may have previously been recognised successfully by the printer.
Our compatible LC123 cartridges currently use a 3rd generation chip. If you still have cartridges containing 1st or 2nd generation chips, it is likely your printer will not recognise them and display a message such as 'Please re-install slowly'.
Although some firmware updates are delivered in other ways, we recommend switching off automatic updates through your printer dashboard or printer properties on your PC in order to minimise the risk of receiving them.
Printers potentially affected by firmware updates are as follows:
Please contact Customer Services for further advice if you think your cartridges have been affected by any past updates.
