scanimage on ADF not working with --batch

I want to scan multiple file with an ADF. This is my device: luca@luca-server:~$ sudo scanimage -L device `xerox_mfp:libusb:001:006' is a Samsung SCX-3400 Series multi-function peripheral If I run this command: luca@luca-server:~$ sudo scanimage --batch --format=tiff It scans correctly the first page on the ADF. But then it flushes all the other pages! This is the output on a test with three pages on the ADF: luca@luca-server:~$ sudo scanimage --batch --format=tiff Scanning -1 pages, incrementing by 1, numbering from 1 Scanning page 1 Scanned page 1. (scanner status = 5) Scanning page 2 scanim
