Hello! When using my HP 4400c with xsane and 150 dpi, the outcome is just a grey/blue picture, not real content of the page. Other DPI settings like 300 produce a normal scan.
I also noticed that the scanner moved forward, stops, then moves a bit backwards and then forward again. This happens multiple times until the page is scanned. How can I further diagnose that and create a useful bugreport? -- kind regards Marco
