[Ubuntu-BR] Scanner HP LaserJet M1212 MFP x Ubuntu 11.10

["André A. Kageyama"]

Tenho uma impressora Multifuncional Laser da HP modelo M1212. Essa 
impressora também manda e recebe faxes, escaneia e copia (xerox).
Eu tinha instalado o Ubuntu 10.04, e tudo na impressora tinha funcionado 
perfeitamente, inclusive a função de scanner. Mas, depois que eu 
atualizei o sistema pro 11.10, o scanner parou de funcionar e tá dando 
esse erro:

Já dei uma olhada nas portas, sendo que a porta que é apontada quando 
rodo o 'debug' como estando ocupada, está destinada exclusivamente pro 
scanner.
O que pode ter acontecido? Na minha leiga opinião, acredito que seja um 
conflito de portas. Mas como resolver/identificar isso? Valeu.
