Epson DS-70 batch-problem

Hallo,

the Epson DS-70 has a manual single sheet “ADF”. Trying to batch-scan
with scanimage

  scanimage -d epsonds --batch="/tmp/A%3d.png" --batch-prompt --format=png

does not work, because on scanning the second page, scanimage fails
with “Document feeder out of documents” even there is a page in the
scanner.

The ADF seems to be recognised correctly:
┌──────────
