SANE - Scanner Access Now Easy

• xsane
• xscanimage - simple GUI, scans directly to file, not possible to view scanned image
• simple-scan - perfect to fast scanning of books, etc ,very simple GUI (photo/text) to create multi-pages documents (view of live scan)
  • project page
  • [-] brightness/contasrt adjustments doesn't work
• skanlite - works slowly, performs some USB polling
• gscan2pdf

apt-get install sane xsane sane-utils
usermod -aG scanner user
usermod -aG lp saned

Prepare udev rules to give access permission to USB:

• Download and extract udev rules from: ScanGear MP package
  • rules are inside `CONTENTS.cpio` file
  • or here: 80-canon_mfp2.rules.gz

• sudo udevadm control --reload-rules

• sudo udevadm trigger --action=add --subsystem-match=usb

List scanners:

scanimage -L

Bus 001 Device 003: ID 04a9:1912 Canon, Inc.

Download and install Canon's ScanGear debian package. This package provides no compatibility with sane, it provides own tool scangearmp2

From sane list, it should be supported by sane-pixma driver: Backend: pixma (0.23.0)

sane-pixma.5

Move all .conf files from /etc/sane.d to speedup autodetection.

mkdir /etc/sane.d/OFF
mv /etc/sane.d/*.conf /etc/sane.d/OFF

Create new config:

/etc/sane.d/canon_lide400.conf

# Autodetect the Canon CanoScan LiDE 400
usb 0x04a9 0x1912

apt-get install build-essential fakeroot devscripts

Download source package from https://packages.debian.org/unstable/source/sane-backends:

• sane-backends_1.0.31-4.dsc
• sane-backends_1.0.31.orig.tar.gz
• sane-backends_1.0.31-4.debian.tar.xz

dpkg-source -x sane-backends_1.0.31-4.dsc
cd sane-backends-1.0.31
dpkg-checkbuilddeps
sudo mk-build-deps -i
# sudo apt-get install libcurl4-gnutls-dev
dpkg -i ../sane-backends.deb

apt-get source sane-backends
cd sane-backends-1.0.27

apt-get build-dep sane-backends
debuild -b -uc -us
dpkg -i ../sane-backends.deb

Remove files installed by distribution:

sudo apt-get purge libsane-extras

apt-get install libjpeg-dev libpng-dev libpoppler-glib-dev
git clone https://gitlab.com/sane-project/backends.git

read INSTALL.linux how to install

libsane.so: undefined reference to `libusb_set_option' Solution: check for old libusb in /usr/local/lib. Mine was from microchip IDE.

Download daily snapshoot from: http://www.sane-project.org/snapshots/

apt-get install libjpeg-dev libpng-dev libpoppler-glib-dev libglib2.0-dev
./configure
make
sudo make install
sudo ldconfig

Now it works:

$ scanimage -L
device `pixma:04A91912_413B3B' is a CANON CanoScan LiDE 400 multi-function peripheral
device `pixma:04A91912' is a CANON CanoScan LiDE 400 multi-function peripheral

Scanner backends supports custom gamma table of size 1024 (10bits). Color range is from 0 to 65535. To get raw color scan from scanner:

scanimage --custom-gamma=yes --gamma-table `gamma4scanimage 1.0 0 1023 1023 65535`  >image.pnm

Options are described here: gamma4scanimage.1

To get white paper scans:

scanimage -p --resolution=150 --custom-gamma=yes --gamma-table `gamma4scanimage 1.0 0 700 1023 65535`  >image.pnm

After restart of computer scanner stops working.

$ scanimage -L

$ scanimage
Output format is not set, using pnm as a default.

Download latest backend snapshot, compile and reinstall - doesn't help.

strace:

openat(AT_FDCWD, "/dev/bus/usb/001/007", O_RDWR|O_CLOEXEC) = 9
ioctl(9, USBDEVFS_GET_CAPABILITIES, 0x56212f5f4098) = 0
ioctl(9, USBDEVFS_CLAIMINTERFACE, 0x7ffff58ba40c) = -1 EBUSY (Device or resource busy)
close(9)                                = 0

SOLUTION:

sudo apt-get remove scanbd
