I believe the issue is with ADF only My option are set as A4 scanning, ADF.
Running de debug mode, i can see the requests for options : [+135,61s] DEBUG: scanner.vala:795: Option 6: name='tl-x' title='Top-left x' type=fixed size=4 unit=mm min=0,000000, max=215,899994, quant=0 cap=soft-select,soft-detect [+135,61s] DEBUG: scanner.vala:798: Description: Top-left x position of scan area.

Then it seems it issues a call for action : [+135,61s] DEBUG: scanner.vala:602: sane_control_option (4, SANE_ACTION_SET_VALUE, source="ADF Duplex") -> (SANE_STATUS_GOOD, "ADF Duplex") [+135,61s] DEBUG: scanner.vala:602: sane_control_option (3, SANE_ACTION_SET_VALUE, mode="Gray") -> (SANE_STATUS_GOOD, "Gray") [+135,61s] DEBUG: scanner.vala:514: sane_control_option (2, SANE_ACTION_SET_VALUE, resolution=200) -> (SANE_STATUS_GOOD, 200) [+135,61s] DEBUG: scanner.vala:554: sane_control_option (8, SANE_ACTION_SET_VALUE, br-x=210,000000) -> (SANE_STATUS_GOOD, 210,000000) [+135,61s] DEBUG: scanner.vala:554: sane_control_option (9, SANE_ACTION_SET_VALUE, br-y=297,000000) -> (SANE_STATUS_GOOD, 297,000000) This will work for flatbed, as the paper, whether A4 of Letter size, is left-aligned (it tl-x=0, which i guess is the default); however with ADF, Letter is centered while A4 paper is centered in he scanning area which is 21.6cm wide; hence there should be a margin of 0.3 cm on each side of the scanning aread that for a flatbed, the offset for top left X should be 0 while for ADF, the A4 page is centered in the scanner area total width, ie, the top left X should be 6/2 = 3mm Am I wrong, or, what is missing here, is a call to set "top left x" ie ,tl-x=3 to offset where the scan range should actually start when scanning A4 with ADF. -- 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/550856 Title: page size setting is broken, use it as default crop or fix it by other means Status in Simple Scan: Fix Released Status in Simple Scan 3.10 series: Fix Released Status in Simple Scan 3.11 series: Fix Released Status in simple-scan package in Ubuntu: Fix Released Status in simple-scan source package in Saucy: Fix Released Status in simple-scan source package in Trusty: Fix Released Bug description: For some SANE drivers simple scan always scans the largest scan area ignoring the "Page Size" setting in the preferences. To reproduce: 1. Open Simple Scan 2. Set page size in Document > Prefrences > Page Size, e.g. to "4x6" 3. Scan a document Expected result: The document is scanned at the requested size Observed result: The document is scanned at the maximum size Regression potential: Low. The fix was to set the page size using an alternative method for drivers that do not support the page-width, page-height options. There is a small chance that these settings might change behaviour / expose bugs on drivers that were previously working.
