[sane-devel] AV122 vertical strips...can you assist?

[Michael Ole Olsen]

That is weird, I have a canon LIDE scanner that makes vertical stripes too

but not in windows, so I dont think its the CCD here?

anyone know what might be causing it then or does the windows driver
compensate for this somehow?

it happens most with reflective surfaces it will not scan them at all.
