Hi again, sorry I was busy those last few days. Here is the result of your suggest command : "scanimage --all-options"
scanimage --all-options All options specific to device `hpaio:/usb/Officejet_6300_series?serial=CN86AFV38X04J5': Scan mode: --mode Lineart|Gray|Color [Color] Selects the scan mode (e.g., lineart, monochrome, or color). --resolution 75|100|150|200|300|600dpi [75] Sets the resolution of the scanned image. Advanced: --contrast -127..127 [0] Controls the contrast of the acquired image. --brightness -127..127 [0] Controls the brightness of the acquired image. --compression None|JPEG [JPEG] Selects the scanner compression method for faster scans, possibly at the expense of image quality. --jpeg-quality 0..100 [10] Sets the scanner JPEG compression factor. Larger numbers mean better compression, and smaller numbers mean better image quality. --batch-scan[=(yes|no)] [no] Enables continuous scanning with automatic document feeder (ADF). --source Auto|Flatbed|ADF [Auto] Selects the scan source (such as a document-feeder). --duplex[=(yes|no)] [no] Enables scanning on both sides of the page. Geometry: --length-measurement Unknown|Approximate|Padded [Padded] Selects how the scanned image length is measured and reported, which is impossible to know in advance for scrollfed scans. -l 0..215.9mm [0] Top-left x position of scan area. -t 0..381mm [0] Top-left y position of scan area. -x 0..215.9mm [215.9] Width of scan-area. -y 0..381mm [381] Height of scan-area. I will now work on getting the source code, trying to run it, and trying to disable options one after the other to see if any is causing issues. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1266310 Title: impossible to scan all pages from feeder with HP OfficeJet 6310 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/simple-scan/+bug/1266310/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
