<p class="MsoNormal">I am head of development at Ambir, the
manufacturer of this scanner. That model has been out of
production for over a decade. It’s likely the unit is EOL
and that clicking you are hearing is coming from the motor.
There are no belts, only gears in the unit and sure it’s
possible the gears could be broken(not sure we’ve ever seen
this failure mode) but more likely the motor is EOL.</p>

<p class="MsoNormal">If the SANE driver worked for it in the
past and it’s not working now, it’s an EOL unit. The control
board is over a decade old and the SANE code is likely to be
the same or older.

<p class="MsoNormal">Also note that the SANE code did not come
from Ambir nor do we endorse or support SANE development on
those models. I know that we have had discussions in the
past about supporting SANE with the current models and may do
so in the future.

<p class="MsoNormal">I am supplying the above information so
that you do not continue to put effort into the codebase for
that model. Also, if you want to check if the unit is EOL you
are free to download the Windows drivers from docketport.com.</p>
