Usage: scanimage [OPTION]...

Start image acquisition on a scanner device and write PNM image data to standard output.

-d, --device-name=DEVICE   use a given scanner device (e.g. hp:/dev/scanner)
    --format=pnm|tiff      file format of output file
-i, --icc-profile=PROFILE  include this ICC profile into TIFF file
-L, --list-devices         show available scanner devices
-f, --formatted-device-list=FORMAT similar to -L, but the FORMAT of the output
                           can be specified: %d (device name), %v (vendor),
                           %m (model), %t (type), and %i (index number)
-b, --batch[=FORMAT]       working in batch mode, FORMAT is `out%d.pnm' or
                           `out%d.tif' by default depending on --format
    --batch-start=#        page number to start naming files with
    --batch-count=#        how many pages to scan in batch mode
    --batch-increment=#    increase number in filename by an amount of #
    --batch-double         increment page number by two for 2sided originals
                           being scanned in a single sided scanner
    --batch-prompt         ask for pressing a key before scanning a page
    --accept-md5-only      only accept authorization requests using md5
-p, --progress             print progress messages
-n, --dont-scan            only set options, don't actually scan
-T, --test                 test backend thoroughly
-h, --help                 display this help message and exit
-v, --verbose              give even more status messages
-B, --buffer-size          change default input buffersize
-V, --version              print version information

Options specific to device `hpaio:/usb/hp_LaserJet_3020?serial=00CNBM044295':
  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 0..100 [50]
        Controls the contrast 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|ADF [Auto]
        Selects the scan source (such as a document-feeder).
    --duplex[=(yes|no)] [inactive]
        Enables scanning on both sides of the page.
  Geometry:
    --length-measurement Unknown|Unlimited|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..228.6mm [0]
        Top-left x position of scan area.
    -t 0..381mm [0]
        Top-left y position of scan area.
    -x 0..228.6mm [228.6]
        Width of scan-area.
    -y 0..381mm [381]
        Height of scan-area.

Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.
