Network scanner pb with maya, works on isadora

[caramba]

Hello,
I'm using a network officejet HP6700 on MINT isadora and maya. Works 100% on isadora with hplip from HP. printer works on maya, but the scanner doesn't.
I get this message after launching xsane :
hpaio:/net/Officejet_6700?ip=192.168.0.12 operation non gérée
sorry for the french. It means that the address is found but something breaks down after that.
The printer/scanner works fine on isadora and on MINT debian, but with maya cinnamon I don't see what's happening.
Any idea ???

Sorry, a correction : the error message appears when clicking on scan in the HP Device Manager,
which is found in preference as HP Toolbox.
Xsane doesn't see the scanner

The question is specific to Mint 13 64
