Thanks for your suggestion. I'm more than willing to do that. If you could kindly tell me where I can get it, I'll be right on it! Forgive my ignorance but I'm still quite new to Linux and SANE but I'm no stranger to C or C++ so happy to get stuck in. I just
need to know where to get the source code you are referring to. Thanks.</div>

> Thanks for your input. For my purposes I probably won't need to scan beyond 40 inches. I use the scanimage frontend on the command line. Where can I find information on how to modify the SANE backend for this model? If the value for document length is somehow
sent to the scanner before the scan then I would like to be able to put in my own values for this. I think this way I could discover what the firmware limit is. Do you know where can I find information on how to modify the Canoscan 9000F backend driver or
any information related to modifying/enhancing SANE scanner drivers? Thanks.<br>

and extend or replace the glass platter. I need help with modifying the sane backend driver. Does anyone know if this is possible? How would I go about doing this? I Any suggestions would be most welcome. Thanks.<br>
