    Canon MultiPass MP730

    I have one item left that is preventing me from removing my windows partition. Ubuntu Hardy 8.04 managed to recognize my Canon MultiPass MP730 without a problem. The one remaining cheviot I have is getting the scanning function to work on this multifunction printer. Every time I try to scan something I receive the message of:
    Unknown message: scanimage: sane_read: Error during device I/O

    Unknown message: Scanned page 1. (scanner status = 9)
    I have tried scanning through multiple programs such as:


    I am not sure what my next step should be.

    I'm in the same boat. Some more info:

    $ scanimage --list-devices
    device `pixma:04A9262F_000000014BD3' is a CANON Canon MultiPASS MP730 multi-function peripheral
    Okay, so the scanner is there...

    $ sane-find-scanner
      # sane-find-scanner will now attempt to detect your scanner. If the
      # result is different from what you expected, first make sure your
      # scanner is powered up and properly connected to your computer.
      # No SCSI scanners found. If you expected something different, make sure that
      # you have loaded a kernel SCSI driver for your SCSI adapter.
    found USB scanner (vendor=0x04a9 [Canon Inc.], product=0x262f [MP730]) at libusb:002:004
      # Your USB scanner was (probably) detected. It may or may not be supported by
      # SANE. Try scanimage -L and read the backend's manpage.
      # Not checking for parallel port scanners.
      # Most Scanners connected to the parallel port or other proprietary ports
      # can't be detected by this program.
      # You may want to run this program as root to find all devices. Once you
      # found the scanner devices, be sure to adjust access permissions as
      # necessary.
    Showing USB location....

    $ scanimage -d pixma:04A9262F_000000014BD3
    # SANE data follows
    637 868
    scanimage: sane_read: Error during device I/O

    $ scanimage -T
    scanimage: scanning image of size 637x868 pixels at 24 bits/pixel
    scanimage: acquiring RGB frame, 8 bits/sample
    scanimage: reading one scanline, 1911 bytes...	FAIL Error: Error during device I/O
    again, wtf. The MP730's all-in-one printer works fine (shot out a test page), but scanning doesn't. It's not a faulty USB cable either. Anyone have a clue what's going on? I get the same message outputted via GUI when i use XSane as well.

    I have been spending a lot of time working through the problems in the MP730 driver. Please take a look at my page at

    Unfortunately, most of the fixes will probably not make it into CVS before S.A.N.E 1.0.20 is released so you will need to apply the patches yourself.
