[sane-devel] ScanJet 4400c 150 dpi only grey, other DPI settings work

[Marco Moock]

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?
