Hello fonseca,
I found this article for when you get replace toner message after replacing the toner cartridge. If you are still having issues after trying these steps, I suggest that you call into our support department for assistance @ 1-800-821-2797.
Bom dia, tenho uma xerox workcentre 7225i que está com a mensagem para trocar toner preto (k) mas o toner nao esta vazio.
Alguma dica.
