hey simon

have you read the manpage sane-avision.5?

i don't have an avision scanner so i'm only guessing at the specific
options for your 'elderly ScanJet 5300C'.  the output from

  $ scanimage -n -A -d avision:libusb:003:005

would be helpful ...

where is your avision.conf file installed?

what happens if you un-comment these lines in your avision.conf file?
#option disable-gamma-table
#option disable-calibration

and run [hopefully you compiled with debug support enabled]
  $ SANE_DEBUG_AVISION=7    scanimage -v -v -v  \
    -d avision:libusb:003:005  --format=png \
    -x216  -y100  -res 200  --mode=gray \
    2> /tmp/default_5300.log  >/tmp/default_5300.png

forward all output files if you want ...
