Hi Sebastien,<br clear="none">

to this one.</i><br clear="none">

ADF has a bug recognising empty document feeder. A work around can
be scanning exact page count.<br clear="none">
<br clear="none">
If you like, we can try to debug this issue. I have no ADF scanner,
so I cannot do this by myself.<br clear="none">
<br clear="none">
On the other hand, does your MX510 scan all resolutions up to
1200dpi in flatbed mode without errors?<br clear="none">
<br clear="none">
Many thanks for your help.<br clear="none">

Cheers,<br clear="none">
