<div dir="ltr">Hi,<div><br></div><div>I acquired an used Canon Color ImageCLASS MF8350Cdn and it didn't work out of the box (Ubuntu 14.04.2), I made some changes to sane-backend master. patch is attached for you.</div><div><br></div><div>I can now scan from the feeder and and regular in both color and black and white.</div><div><br></div><div>Oddities:</div><div>* Simple Scan complains with "Error communicating with scanner" at the end when scanning from the feeder.</div><div>* Seems to make more noise than using the proprietary driver on OSX</div><div>* I need to run it as root, but I think that is an Ubuntu / install issue on my side</div><div><br></div><div>Notes:</div><div>You need to set the scanner to "Remote Scanner". There is also a "Computer" scan option, but that seems to tell the computer what to scan (e.g. PDF, email, save, ..) and that menu doesn't even come up using the sane backend.</div><div><br></div><div><br></div><div>Where I am unsure on the patch:</div><div><br></div><div>I followed the MF4100 and added the MF8350 to the same places in the code to use iclass_exec, not sure that was right/wrong.</div><div><br></div><div>The scanner is supposed to be 600x600 dpi, so not sure I defined that correctly with 600, 0</div><div><br></div><div>And the 640 / 1050 was also just copied from one of the similar printers.</div><div><br></div><div>Also I haven't tried network scanning yet.</div><div><br></div><div>Also in case you need it the lsusb output:</div><div><div>Device Descriptor:</div><div> bLength         18</div><div> bDescriptorType     1</div><div> bcdUSB        2.00</div><div> bDeviceClass       0 (Defined at Interface level)</div><div> bDeviceSubClass     0 </div><div> bDeviceProtocol     0 </div><div> bMaxPacketSize0     64</div><div> idVendor      0x04a9 Canon, Inc.</div><div> idProduct      0x2708 </div><div> bcdDevice       0.00</div><div> iManufacturer      1 Canon,Inc.</div><div> iProduct         2 MF8350</div><div> bNumConfigurations    1<br></div><div><br></div></div><div><br></div><div>Thank you and best regards,</div><div>Florian</div><div><br></div><div><br></div><div><br></div><div><br></div></div>
