There is no reason to think that any particular scanner will support that capability. Many of them get information about the total length of the scan before they start, and there is a firmware limit to that value. You will need a simplistic scanner that just streams data of an indeterminate

The DR-G2140 is not yet supported by sane-backends. Perhaps you can get a log and we can try to figure out what it needs. Many times, this does not give us enough info, so we need to get a log of the Windows driver in action instead. But for now, lets try sane. Please run the following as root:
