Epson WF7710 supports A3 scanning, and this may be the cause of the problem.
scanimage --help gives Options specific to device `escl:https://192.168.1.73:443': Scan mode: --mode Lineart|Gray|Color [Lineart] Selects the scan mode (e.g., lineart, monochrome, or color). --resolution 100|200|300|600|1200dpi [100] Sets the resolution of the scanned image. --source Flatbed|ADF|ADF Duplex [Flatbed] Selects the scan source (such as a document-feeder). Geometry: -l 0..289.052mm [0] Top-left x position of scan area. -t 0..423.672mm [0] Top-left y position of scan area. -x 8.12799..297.18mm [297.18] Width of scan-area. -y 8.12799..431.8mm [431.8] Height of scan-area. Enhancement: --preview[=(yes|no)] [no] Request a preview-quality scan. --preview-in-gray[=(yes|no)] [no] Request that all previews are done in monochrome mode. On a three-pass scanner this cuts down the number of passes to one and on a one-pass scanner, it reduces the memory requirements and scan-time of the preview. --brightness -100..100 (in steps of 1) [inactive] Controls the brightness of the acquired image. --contrast -100..100 (in steps of 1) [inactive] Controls the contrast of the acquired image. --sharpen 0..3 (in steps of 1) [inactive] Set sharpen value. --threshold 0..255 (in steps of 1) [-1226889112] Select minimum-brightness to get a white point Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.

The scan is physically started before the segmentation fault occurs. Giving "-l N" seems to be the way to fix the left-offset, and autochanges br-x. A value of about 67 would seem right - but we can't get to that point. I have got the Epson proprietary linux scan utility to work; and (apart from single-sided scan seeming to scan only the reverse side of the paper!) it scans correctly. -- 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/2048433 Title: scanning from ADF on Epson WF-7710 has page offset Status in simple-scan package in Ubuntu: New Bug description: Scanning from the ADF on my Epson WF-7710 produces images with a left margin about 4 times as large as when scanning from the flatbed, so that the right-hand side of the page is lost. Top and bottom margins are handled correctly. The scanner is connected via the local ethernet.
