Attached patch should fix this. The patch is based on recent git code.

It's not stupid. Maybe you started the job and forgot to put the paper
into the ADF. Then the job should start scanning if you put the paper
into the ADF *before* timeout counted down to 0 and aborts the job.
Please test, if scanning starts if you put paper into the ADF during
timeout counts down.
