Can't find scanner after update

[Helder Terra]

It was only yesterday that I updated my Kubuntu Maverick to Natty, and 
despite some issues it was working fine.

But today I've tried to scan a page and the system simpkyc cannot find 
the scanner (it's a Lexamark all in one printer x1195). The printing is 
working normally and the lsusb finds the printer/scanner as it used to, 
but skan lite, or simple scan, fail to notice the scanner.

You guys have any idea of what's happening?

Thank you all.
