The scans from my Canoscan N650U USB scanner are too light. I have tried various settings for brightness and contrast but these have been ignored. I used to have an HP ScanJet 4C SCSI scanner that worked great and I could adjust the brightness & contrast to my hearts's content. The HP's power supply has died however, leaving me with just the Canon.

I can adjust the brightness and contrast fine using xsane.

I was using Simple Scan 3.22.0. I then built and installed 3.23.3 where I am now.

Thanks for any help.
