[Impostazioni di default] Ricoh IS450d
 

Hello, I'd like to modify the default settings of my Ricoh IS450d, but
I cannot do it.
The scanner driver don't let me save settings.
Every time the scan window appears I read A3 - plain paper.
I'd like to have A4 and autofeed.
Perhaps can I find something in the registry?
Thank you very much.
Carlo.
