Hello, Sorry I have already sent this message to the sane-standard list but I have noticed that it was not the good one.
I have a CANON Pixma MX 510, am I am trying to use libsane. I? would like to use the automatic document feeder to aquire automatically all the documents available. I have tried several way and I have found problem with all of them to detect that there is no more document in the document feeder. - sane_start or sane_read never returns SANE_STATUS_NO_DOCS -in synchrone mode, sane_read is blocked, and if I call sane_cancel from another thread, this call is also definitly blocked -The asynchrone mode doen't seem to work. If I call sane_read when a document is available, it returns immediatly but read len =0 Do you have other suggestions? Or do you think that there is problems with the PIXMA implementation? Thank you?
