[sane-devel] Problems with Canon MX715

[Rolf Bensch]

Hello,

please note that MX710 is experimental in 1.0.23. You need to set the
environment variable PIXMA_EXPERIMENT to non-zero, e.g.
export PIXMA_EXPERIMENT=1.

You will get a corresponding hint after enabling debug outputs on the
command line, e.g. with
export SANE_DEBUG_PIXMA=1

Alternatively you can use 1.0.24git. Then you don't need to use
PIXMA_EXPERIMENT.

Cheers,
Rolf
