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
36       ignored.   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.  Under UNIX, the directories
58              are  separated  by a colon (`:'), under OS/2, they are separated
59              by a semi-colon (`;').  If this variable is not set, the config‐
60              uration  file is searched in two default directories: first, the
61              current working directory (.)  and then in /etc/sane.d.  If  the
62              value  of the environment variable ends with the directory sepa‐
63              rator character, then the default directories are searched after
64              the  explicitly  specified  directories.   For  example, setting
65              SANE_CONFIG_DIR to "/tmp/config:" would  result  in  directories
66              tmp/config, ., and /etc/sane.d being searched (in this order).
67
68       SANE_DEBUG_HP5400
69              If  the  library  was  compiled with debug support enabled, this
70              environment variable controls the debug level for this  backend.
71              Higher debug levels increase the verbosity of the output.
72
73              Example: export SANE_DEBUG_HP5400=4

BUGS

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