This may be related to the timing changes I made to the pixma network code earlier this week. I works ok on my MB5050 but may be the casue of your problems: please try to change the mimimum timing in backende/pixma_bjnp_private.h on line 83: #define BJNP_BC_RESPONSE_TIMEOUT 500 (500 msec) to a larger value, for example #define BJNP_BC_RESPONSE_TIMEOUT 1000 to make the timeout 1000 msec = 1 second This may solve your issue. You did not tell us what scanner model you are using, so there may be some other issues lurking in the backend proper (I had to fix the button detection for my MB5050 to make the backend recognize the buttons on that scanner). Please note that to fully automate button controlled scanning you will need scanbd as well. Scanbd is a nice tool that continuously monitors the buttons and starts a script to process and forward the scan result as required.
