Canon Pixma MX850: can print but can't scan from it

[atlanticza]

Have a networked Pixma which scanned fine with my old Mac Pro but this new iMac doesn't. (See attached pic) Downloaded lastest driver. And checked firewall settings Other iMacs here have no problems. Any here with a solution? Thanks in advance.

Do the Macs working with the scanner/printer don't run Mac OS X 10.7 Lion?

Scans fine with the other Macs running Lion.

Deleting the appropriate Canon apps, reinstalled... works.
