scanning via scanimage
Brother has a broad variety of printer/scanner driver for linux. Also there are quite good installation instructions (step-by-step and images for the output). After installing the driver for scanning, you will need a utility to scan from the printer. scanimage is just the right program for that. With
# scanimage –format=tiff -v > ~/image.tiff
you will have an image named image.tiff in your home folder. If your scanner is not the default scanner you can work your device with
# scanimage -L
out, because it gives you a list of scanning devices. The option -d can specify another device, if you have more than one.
