Uma ótima impressora, porém sem suporte e suprimentos. Estou a mais de 6 meses tentando comprar um novo toner e não consigo nem com os fornecedores do próprio site da Lexmark.

Impresora fácil de instalar y vincular al equipo.

Double sided printing works reasonably effectively. Haven’t used the auto feed yet. Set up was a pain. Had to get in touch with CS as there is no specific driver update provided for the MX431 on the site but we figured out a solution. Connecting wifi was a problem so connected via cable.

other than a small paper tray the unit is excellent much faster but smaller and lighter than my older Lexmark, which is going on for over 20 years. I simply trust lexmark, and their customer support is excellent
