Start exposure with the settings from the scanner entry. CIS
Calibration and exposure uses a broader spectrum now. Expsoure limit is increased to 50 loops. Genius Vivid 4x is reported to work so the UNTESTED label is removed now. Visioneer 7300 is reported to work so the UNTESTED label is removed now. Genius ColorPage Vivid 1200XE: Removed UNTESTED label. Fixed resolutions. Adjusted margins. Fixed color order. Fixed linedistance. Adjusted AFE. Mustek ScanExpress 1248 UB: Fixed margins. Adjusted AFE. Adjusted exposure. Adjusted gamma. Changed status to "complete". Mustek BearPaw 2400 CU Plus: Adsusted exposure and AFE parameters. Hopefully stripes and similar trouble are gone now. Mustek BearPaw 1200 CU: Increased exposure to avoid vertical lines. Updated manual page.merge-requests/1/head
