Genuine OEM Lexmark T634 dtn Toners

The T634 dtn's 12A7362 black toner is high-yield, while 12A7365 is extra-high-yield. The latter lets you print more before another cartridge change. Choose between those capacities according to how much printing you want from each cartridge, not the presence of a Return Program label.

Toner Buzz carries genuine Lexmark black cartridges in these capacities, with Return Program choices alongside them. The return arrangement is a separate commitment to use a cartridge once and return it to Lexmark. Keep that condition distinct from your choice of toner capacity.
