Re: SANE with Samsung SCX-4x21F Getting IO Error

Hello,


Hope you are having a great day. The output from the command as follow:

 >  ➜ scanimage -L
 > device `xerox_mfp:libusb:003:023' is a SAMSUNG ORION multi-function 
peripheral
 > device `smfp:usb;04e8;3419;SERIALNUMBERREDACTED.' is a Samsung 
SCX-4x21 Series on USB Scanner


I have already tried both and both didn't scan. The result from the 
previous email is from the xerox_mfp one

Thank you very much.
