scanimage: scanning image of size 638x877 pixels at 24 bits/pixel

scanimage: acquiring RGB frame, 8 bits/sample

scanimage: reading one scanline, 1914 bytes...  FAIL Error: Error during device I/O

Usage: scanimage [OPTION]...



Start image acquisition on a scanner device and write image data to

standard output.



Parameters are separated by a blank from single-character options (e.g.

-d epson) and by a "=" from multi-character options (e.g. --device-name=epson).

-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), %i (index number), and

                           %n (newline)

-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 page number in filename by #

    --batch-double         increment page number by two, same as

                           --batch-increment=2

    --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

-A, --all-options          list all available backend options

-h, --help                 display this help message and exit

-v, --verbose              give even more status messages

-B, --buffer-size=#        change input buffer size (in kB, default 32)

-V, --version              print version information



Options specific to device `pixma:04A91716_000000':

  Scan mode:

    --resolution auto||75|150|300|600|1200dpi [75]

        Sets the resolution of the scanned image.

    --mode auto|Color|Gray [Color]

        Selects the scan mode (e.g., lineart, monochrome, or color).

    --source Flatbed [Flatbed]

        Selects the scan source (such as a document-feeder).

    --button-controlled[=(yes|no)] [no]

        When enabled, scan process will not start immediately. To proceed,

        press "SCAN" button (for MP150) or "COLOR" button (for other models).

        To cancel, press "GRAY" button.

  Gamma:

    --custom-gamma[=(auto|yes|no)] [yes]

        Determines whether a builtin or a custom gamma-table should be used.

    --gamma-table auto|0..255,...

        Gamma-correction table.  In color mode this option equally affects the

        red, green, and blue channels simultaneously (i.e., it is an intensity

        gamma table).

  Geometry:

    -l auto|0..216.069mm [0]

        Top-left x position of scan area.

    -t auto|0..297.011mm [0]

        Top-left y position of scan area.

    -x auto|0..216.069mm [216.069]

        Width of scan-area.

    -y auto|0..297.011mm [297.011]

        Height of scan-area.

  Buttons:

    --button-update

        Update button state

    --button-1  [0]

        Button 1

    --button-2  [0]
