I've checked the example of a long Marriage Certificate on my Canon GX5060 by scanning from the AFD onto a local USB stick. It scans the whole certificate perfectly into a pdf on the stick. Thus, I conclude that it should be possible to connect via network via a sane module version that supports scanning long documents. Any chance to get that implemented?
