[sane-devel] Detect scan button on ScanSnap S1500 (sane-fujitsu backend)

[Mikael Nordenberg]

Hi list.

I've tried really hard to find information about how to detect if the button
on my scanner is pressed.
I've got a ScanSnap S1500, which is supported by the fujitsu backend, and
works as expected using for example scanimage.

The scanner itself only has one backlit button titled scan. If I press it,
it starts to blink for a couple of seconds and then goes back to normal
(which is constant lit).

If I type scanimage --help I'm presented with numerous sensor options,
including the following:
--scan[=(yes|no)] [no] [hardware]
Scan button

Typing scanimage --scan results in:
scanimage: unrecognized option '--scan'

(None of the other sensor options is recognised either.)

I've tried to access the scanner via saned using the network protocol, but
the scan-option (#83) always responds false, even if I press and hold the
scan button.

Is this model not supported when detecting buttons, or am I doing something
completely wrong?

Best regards,
Mikael

Fortunately, it's the latter. Scanimage is not smart enough to monitor
the buttons exposed by the driver and perform an action when they are
pressed. Instead, you need a daemon which does this. There are a
couple of them in our old 'experimental' cvs tree, but they are not
widely used. One of these days someone will come forward with enough
time to make one of these a more permanent addition to the
sane-backends package.
