[sane-devel] CANON Pixma MX 510

[sebastien]

Hi Rolf,
I confirm that I have succeed to scan all resolutions up to 1200dpi.

I would like to help you to debug the ADF. What do you need?

Hi Sebastien,

Sorry, I used the wrong email address for SANE ml. Please answer to this one.

ADF has a bug recognising empty document feeder. A work around can
    be scanning exact page count.

If you like, we can try to debug this issue. I have no ADF scanner,
    so I cannot do this by myself.

On the other hand, does your MX510 scan all resolutions up to
    1200dpi in flatbed mode without errors?

Many thanks for your help.

Cheers,
Rolf
