### Tips
The default scanner device is set to `fujitsu`. If you have another scanner,
you will need to use the `-x`/`--device` argument to specify your scanner.
See below for how to get the list of available devices.
The scanners and scanner drivers vary in features they support. This script
provides several options to the underlying scanner driver by default, and
these options may not be supported by your scanner/scanner driver. If
you are receiving an error about `--page-width`/`--page-height` being
unrecognized options, try the `--no-default-size` option. If you receive an
error about the `--mode` value being invalid, try `--mode-hw-default`
