	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.		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~~==		==Background==
	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.

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" />		This issue does not affect OEM Brother cartridges, as they use a different chip design that does not require a battery.
