<div dir="ltr">Hello folks! A few years ago I posted about my Xerox DocuMate 510 and its strange colored bands when using Sane. Unfortunately back then, I didn't have time to dig deeper into the problem.<div><br></div>
<div>I tried this scanner again recently, and found similar results.<div><br></div><div>Xsane now crashes after init, probably due to my running two monitors. Simple Scan starts up fine and runs normally.</div><div><br></div>

<div><br></div><div>I'm looking for some help on getting started. I noticed many of the scanners defined have various flags, perhaps one of those flags should be set for the (Visioneer) Xerox DocuMate 510?</div><div>
