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.
