The [[Brother Industries, Ltd.|'''Brother''']] DCP-L3550CDW printer requires toner cartridges with embedded chips for authentication. Some '''aftermarket (non-OEM) cartridges''' include '''battery-powered chips''', which can lead to recognition failures if the battery depletes. However, '''genuine Brother cartridges do not contain a battery''', and the battery issue is not caused by the printer itself.

==Issue Description==

Aftermarket toner manufacturers use '''battery-powered chips''' to bypass Brother’s authentication system. When the '''1.5V battery inside these third-party chips depletes''', the printer fails to recognize the cartridge, displaying a misleading "No Toner" error message, even if toner remains in the cartridge.

This issue '''does not affect OEM Brother cartridges''', as they use '''a different chip design that does not require a battery'''. Brother’s chip system is primarily used for '''tracking toner levels and verifying cartridge authenticity''', which can restrict third-party toner compatibility but is not responsible for battery failures in non-OEM cartridges.<ref name="printerforums1" />

==User-Discovered Solutions==

Users on Printer Forums reported success with '''replacing the battery or swapping the chip''' from a recognized cartridge.<ref name="printerforums2" /> Others have noted that pressing the '''red X and back arrow on the printer control panel''' allows access to toner status and may temporarily resolve the issue.<ref name="printerforums3" />

==Firmware-Related Issues==

Firmware updates have been linked to preventing the use of third-party toner chips. Several users reported that after updating their printer to '''firmware version 1.59''', previously working third-party cartridges were no longer recognized, triggering the "No Toner" error.<ref name="printerforums1" /> This is '''separate''' from the issue of dead batteries on aftermarket cartridges.  

==Consumer Impact Summary==

While Brother's chip-based authentication system '''restricts the use of non-OEM toner cartridges''', the '''battery issue is caused by third-party cartridge manufacturers, not Brother'''. The chip requirement itself can be seen as a method to enforce '''a closed ecosystem''', potentially increasing costs for consumers. However, the '''battery-powered chip design is an independent choice made by aftermarket manufacturers''', not a function of the Brother printer or its OEM cartridges.<ref name="printerforums2" />

==Related Incidents==

This issue primarily affects '''aftermarket toner cartridges''' used in multiple Brother printer models:
