Your scanner has a DIN A3 ADF and you use those plastic bars (how are they called?) to center your letter sized paper. The origin of the scanning area (-x -y -l -t) is 0/0 in the picture below if you use --papersize Letter, not the left side of the A3 ADF. | <----------- DIN A3 ---------->| | | 0/0 | | | | <- Letter -> | | | | | | | | | | | | If you put mixed-size paper in the adf with different paper width (e.g letter and A5) you'll more likely get a paper jam and the A5 paper will probably be skewed. The resulting image of the A5 paper will have letter size if -x and -y are set to letter size. I think this subject is better described in one of that guides of your scanner (have a look at the fujitsu home page). -- Oliver
