Genuine OEM Lexmark Optra T612 Toners

The Optra T612 uses black toner with a choice of cartridge capacities. The smaller 12A5840 is a Return Program cartridge. So is high-yield 12A5845 toner, which gives you more printing between changes. Either choice includes sending the empty cartridge back to Lexmark.

Toner Buzz carries genuine Lexmark toner for the T612, including high-yield 12A5745 toner outside the Return Program and 12A5849 toner intended for label printing. A separate 99A1017 charge roller is also part of the selection; that is a maintenance item rather than another toner option.
