The use of the transparency unit in Canon 9000F Mark II requires to take the regular white background away from the covering lid, beneath with the actual backlight of the transparency unit resides.
Any scanning attempt with the transparency unit as source while the backlight is hidden by the white background yields the error described above – which is, sadly, not very descriptly. After taking way the background the transparency unit works like a charm. @Jelle you might try whether this works for you. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1744775 Title: "Operation was cancelled" when trying to use Transparency Unit in Canon 9000F Mark II Status in sane-backends package in Ubuntu: Confirmed Bug description: I'm trying to scan foto negatives using this command (that used to work in previous Ubuntu versions): scanimage --device-name pixma:04A9190D --source "Transparency Unit" --resolution "2400" --format "tiff" --mode Color -l 76 -x 66 > test.tiff But I get this error: scanimage: sane_read: Operation was cancelled Note: scanning regular images (using the Flatbed source) works fine.
