MX Navigator
My problem is slightly different.
I got a new 27" iMac (Yay!) The MX850 is connected via Ethernet, not USB. It's actually in a different room.
I "Migrated" all my software from my old 24" iMac, most worked but the Canon scanning did not. Looked at a lot of these threads, tried a lot of stuff, reinstalled the Canon drivers, and I got to this point:
1. If I scan from within MX Navigator, everything works including saving as a PDF file.
2. If I scan from the MX850 panel as a "document" (i.e. a JPG), it works fine, saves in MX Navigator as normal.
3. If I scan from the MX850 panel as a "PDF document" (i.e. a PDF), I then get the dialog box "Unable to save file. The system cannot find the path specified."
This appears to have something to do with PDF versus JPG.
I tried a lot of things, and got the new computer in a mess, and I wanted to reinitialize anyway, so I did an "archive and install" following these instructions:

I am slowly getting everything back to normal. First thing I tested/noticed was that the Canon print drivers where already installed and they worked fine. Also the Apple version of scanning worked fine: use the "Image Capture" application and I could scan just fine from the computer. The front panel buttons don't work, the scan button doesn't detect my Mac. I would like the front panel buttons to work - did I mention the MX850 is in a different room?
So I reinstalled these items from the Canon web site:
http://www.usa.canon.com/cusa/snow_...rinters/inkjet/pixma_mx850#DriversAndSoftware
1. MX Navigator (mpnexosx111ea8-2.dmg)
2. IJ Network Tool (ntosxm270ea8-2.dmg)
3. MP Drivers (mx850sosxns10ea7-3.dmg)
Note I did not install ALL the software from this site, as I am only interested in getting the front-panel scanning to work...
Also, I am confident that I did NOT need to install the IJ Network Tool as the MP Drivers include it, but I didn't know that at the time.
Rebooted and configured the scanner - this was a little confusing as right after the reboot the IJ Network tool wants to configure the PRINTER and the dialog looks quite a bit like the one to configure the SCANNER. Since I don't need to use the Canon software to configure the printer (the Mac software is working just fine) I cancelled it, then went to the right-hand menu bar and selected the "Open Settings..." from the Canon IJ menu. And once again, I am back to the point where everything works EXCEPT scanning to PDF from the front panel of the MX850. Naturally, this is the function that I want to work the most...
I hope this lengthy post helps someone else, and if anyone has any hints about what I should try next, I would greatly appreciate it!
