NAME

6       sane-hp5400 - SANE backend for Hewlett-Packard 54XX scanners
7

DESCRIPTION

9       The  sane-hp5400  library  implements  a SANE (Scanner Access Now Easy)
10       backend that provides  access  to  the  following  Hewlett-Packard  USB
11       flatbed scanners:
12
13              ScanJet 5400C
14              ScanJet 5470C
15              ScanJet 5490C
16
17       More   details   can   be   found   on   the  hp5400  backend  homepage
18       http://hp5400backend.sourceforge.net/.
19
20       This is ALPHA software. Keep your hand at the scanner's plug and unplug
21       it,  if  the  head bumps at the end of the scan area. See also the BUGS
22       section.
23
24       If you own a scanner other than the ones listed above that  works  with
25       this  backend,  please  let us know this by sending the scanner's exact
26       model  name  and  the  USB   vendor   and   device   ids   (e.g.   from
27       /proc/bus/usb/devices,  sane-find-scanner(1)  or syslog) to us. Even if
28       the scanner's name is only slightly different from the models mentioned
29       above, please let us know.

CONFIGURATION

32       The  contents of the hp5400.conf file is a list of usb lines containing
33       vendor and product ids that correspond to USB scanners.  The  file  can
34       also  contain  the  names of device files that correspond to an HP 54XX
35       scanner.  Empty lines and lines starting with a hash mark (#)  are  ig‐
36       nored.   The  scanners  are  autodetected  by  usb vendor_id product_id
37       statements which are already included  into  hp5400.conf.   "vendor_id"
38       and  "product_id" are hexadecimal numbers that identify the scanner. If
39       autodetection does not work, add the device name of your scanner to the
40       configuration file, e.g.  /dev/usb/scanner0.
41

FILES

43       /etc/sane.d/hp5400.conf
44              The   backend   configuration  file  (see  also  description  of
45              SANE_CONFIG_DIR below).
46
47       /usr/lib64/sane/libsane-hp5400.a
48              The static library implementing this backend.
49
50       /usr/lib64/sane/libsane-hp5400.so
51              The shared library implementing this backend (present on systems
52              that support dynamic loading).
53

ENVIRONMENT

55       SANE_CONFIG_DIR
56              This environment variable specifies the list of directories that
57              may contain the configuration file.  On *NIX systems, the direc‐
58              tories are separated by a colon (`:'), under OS/2, they are sep‐
59              arated by a semi-colon (`;').  If this variable is not set,  the
60              configuration  file  is  searched  in  two  default directories:
61              first,  the  current  working  directory  (.)    and   then   in
62              /etc/sane.d.  If the value of the environment variable ends with
63              the directory separator character, then the default  directories
64              are  searched  after  the explicitly specified directories.  For
65              example, setting SANE_CONFIG_DIR to "/tmp/config:" would  result
66              in directories tmp/config, ., and /etc/sane.d being searched (in
67              this order).
68
69       SANE_DEBUG_HP5400
70              If the library was compiled with debug support enabled, this en‐
71              vironment  variable  controls  the debug level for this backend.
72              Higher debug levels increase the verbosity of the output.
73
74              Example: export SANE_DEBUG_HP5400=4

BUGS

89       Scanning is only tested with Linux/ix86/gcc. Be careful when testing on
90       other  operating  systems  and  especially on big-endian platforms. The
91       scanner may get wrong data.
