    Scanner not detected


    I'm having trouble detecting my scanner (CanoScan FB 320P).

    According to the sane documentation this scanner is supported by xsane and its backend can be edited in canon_pp.conf.
    However, when trying to detect it, i get nothing.
    Code:
    [root@localhost jeremie]# sane-find-scanner
    
      # No SCSI scanners found. If you expected something different, make sure that
      # you have loaded a SCSI driver for your SCSI adapter.
    
      # No USB scanners found. If you expected something different, make sure that
      # you have loaded a driver for your USB host controller and have installed a
      # kernel scanner module.
    
      # Not checking for parallel port scanners.
    
      # Most Scanners connected to the parallel port or other proprietary ports
      # can't be detected by this program.
    Code:
    [root@localhost jeremie]# sane-find-scanner -v

    Update

    ok, just noticed that parallel port scanners are not detected automatically by sane-find-scanner.

    I have nothing else connected to the parallel port. The scanner works fine under Windows 98.

    I have updated the sane-backends which include sane-canon_pp which supports the FB320P.

    I uncommented the canon_pp line in /etc/sane.d/dll.conf.

    In /etc/sane.d/canon_pp.conf, the following are set:

    Code:
    ieee1284 parport0 
    calibrate ~/.sane/canon_pp-calibration-pp0 parport0 
    init_mode FB620P parport0
    (I've also tries init_mode AUTO, same results)


    After all that, when I run xsane, either in my account or as root, nothing is detected.

    help, anyone that got a scanner to work on PP...

    In the configuration files sane sets a model as default . This is the model which it keeps detecting until you comment it out and uncomment your model . Then select it manually.

    They could explain this a bit better couldn't they?

    hi,

    I have tried in that way also, which u have specified for me..
    Still it is not working, my model is CanonN640P...
    Here in my office this for the first time we are performing few
    test cases on scanner, which is connected to parallel port...
    I have modified the file canon_pp.conf in the sane.d directory as
    u said, still i am unable to brope the device(I use sane-find-scanner).

    Chidrup_n try using MLCC config......computer->hardware->scanner
    to find scanner but certainly if it keeps finding the same wrong one then you must find the wrong one and comment it out.
    It was tricky
