Hallo!
I've installed linux some weeks agon and now tried to use my scanner.
I'm using sane 0.73 and when I enter "xerox" it says:
scanimage: open of device snapscan:/dev/scanner failed: Invalid argument
pgmtopbm: EOF / read error reading magic number
pbmtolj: EOF / read error reading magic number
lpr: stdin: empty input file
--------------------------------------------
xerox reads as follows:
#!/bin/sh
#
# This is a xerox script for Laserjet Printer.
# To get use of Postscript change the Printercommand and enable the
# command at the end of this File.
#
DEV=snapscan:/dev/scanner
RES=300
#PAPERTYPE=letter
PAPERTYPE=a4
#PRINTERTYPE=ps
PRINTERTYPE=lj
#
# Non-printable area (left, right, top, and bottom margins):
#
LMARGIN=0.0
RMARGIN=0.0
TMARGIN=0.25
BMARGIN=0.0
#
# Scanner-specific options:
#
DEVOPTS="--mode Gray"
#DEVOPTS="$DEVOPTS --custom-gamma=yes --gamma-table [0]0-[64]128-[255]255"
#DEVOPTS="$DEVOPTS --backtrack=yes" # needed for Mustek 12000SP
#
# Printer Command/Resolution
PRES=$RES # change this if other Res. is desired
#
# Papersize in inch
if [ "$PAPERTYPE" = "letter" ]; then
WIDTH=8; HEIGHT=10
else
# assume a4 paper
WIDTH=8.27; HEIGHT=11.69
fi

SCANWIDTH=`bc <<_EOF_
scale=3
$WIDTH-$LMARGIN-$RMARGIN
_EOF_`
SCANHEIGHT=`bc <<_EOF_
scale=3
$HEIGHT-$TMARGIN-$BMARGIN
_EOF_`
#
SCALE=`bc << _EOF_
scale=3
75/$RES
_EOF_`

if [ "$PRINTERTYPE" = "ps" ]; then
POST="pnmtops -rle -scale $SCALE -dpi $PRES | lpr"
else
POST="pgmtopbm | pbmtolj -resolution $PRES | lpr -Praw"
fi

scanimage -d $DEV \
-x $SCANWIDTH\" -y $SCANHEIGHT\" -l $LMARGIN\" -t $TMARGIN\" \
--resolution $RES $DEVOPTS | eval $POST
----------------------------------------------------------
Does anybody have an idea what's going wrong?
TIA Erwin.
