I have a Brother MFC-J630W all-in-one printer-scanner-fax.  I have the sane software installed, along with the sane driver provided by Brother.  The scanner has a document feeder.I'm using this command: scanimage --device-name $device --resolution 300 > $output_fileEverything was working well until I used the document feeder to scan a legal-sized page.  Now, if I put any letter-sized page into the document feeder, I end up with a legal-sized scan.The biggest problem is, I don't (yet) know if this is a problem on the scanner side, or on the software side.  All I know for certain is that the pnm file created by scanimage is legal-sized.Does anybody have any ideas for troubleshooting and/or fixing this problem?
Scanner assumes document feeder is legal-sized

I have Brother A3 (MFC 6490CW) scanner and to scan A4 on that I use:scanimage -x 209.981 -y 296.973 -l 43.496 --format=tiff \    --batch=xx_00%03d.tif --batch-start=0I had to experiment a bit to get the '-l' value right, my feeder is centered.It takes a while before scanimage connect to the scanner and starts.
