I used the calibration sheet that came in the box with the used scanner. (Found at a charity thrift store for $3USD :-) )
It's a white bar with three black arrows indicating direction, a big white space, followed by a black space. The whole thing is approx. half of a US letter-sized sheet. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to simple-scan in Ubuntu. https://bugs.launchpad.net/bugs/1712663 Title: Visioneer RoadWarrior Scanner [Sane] Status in simple-scan package in Ubuntu: Incomplete Bug description: I just picked up one of these portable scanners, it works well in Windows. In Linux and either xsane or simple-scan however it always scans a completely black page. Thinking it was a calibration issue I ran:- SANE_DEBUG_GENESYS=255 scanimage -d genesys --calibrate 2>calibrate.log Which at first reported it couldn't find the correct sheet. I made one using: http://www.fixya.com/support/t17003105-calibration_sheet_visioneer_roadwarrior and the errors went away This is resolved. The calibration value "01 e8 00 00 00" is written. There is still an error in the log but it appears to be OK. I'm unsure if it's calibration anyhow as it worked OK-ish in Windows (washed out, but had an image). Scans are still completely black.
