Hi Alan,

This time with one 'l'.

'scanimage -h' shows all options of your scanner, if you scanner has
been switched to "Remote Scanner" mode before. Some options come from
the backend and are not described in the doc of scanimage. Please read
the manpage of the Pixma backend: 'man sane-pixma' and note that button
scan isn't supported for your scanner.

Alternatively to scanimage I'm using xsane as gui frontend.

Hope this helps.
