FAQ

Q: Does the backend support the scanner buttons?

A: Yes, the Avision backend was the first one introducing such a functionality. I implemented a tiny demo daemon and there is a graphical KDE systray program available as well.

Q: The backend report a wrong sheet size?

A: Some Avision scanners report no (AV 630) or a wrong scan-area. Use the "option force-a4" option in your sane config file (e.g. /usr/etc/sane.d/avision).

Q: Do the HP (53xx and 74xx series) or other Avision OEM scanner (such as the Minolta Dimage dia/film scanner or Xeros, Kodak, ... document scanner) work?

A: Yes. They should all work now. Only the 5370 has some image-corruption problems and the 7400 needs to be some tweaking for ADF. Please try the latest source available.

You also no longer need Oliver Neukum's hpusbscsi (SCSI emulation) kernel module. The backend now accesses the USB devices via the SANEi/USB and so via libusb.

Q: Does the Avision parallel scanners work?

A: No. I do not own a parallel-port-scanner and at this day of age they are not really important for us. I got private eMails from other people who try to log and "decrypt" the parallel-port-traffic, but there is no useable code, yet.
