I'm having trouble with a Canon imageCLASS MF8450c printer/scanner/copier (it fails to save scans to SMB shares). I've eliminated the obvious problems, so now I am just looking to do a factory reset of the device and hope that resolves the issue.

I can't figure out how to do a hard reset, though. The manual and support site are not helpful, and hunting through the menu system is like exploring a labyrinth. Any ideas?

Since it is a business class Printer, that info will not be in any of the publicly available user manuals, only in the private Service manual. –  Moab Jan 18 '11 at 22:25

And to think I couldn't be more angry about this. –  benzado Jan 19 '11 at 19:24

Enter 'Menu' and then '#' - this gets you into Service Mode.

you can reset settings individually, but you should know what you are doing....

For example should you need to clear the password, you can do so by cycling to the PASSWORD CLEAR option under 6.CLEAR DATA....

You can only find this out from Canon service by faxing them a copy of your purchase receipt.....!! Canon is crazy for making it so difficult and no doubt have lost mucho dinero from professional IT managers who choose other products in Enterprise settings....

Called Canon support. After walking through all the network settings that I already checked myself, I was informed that to learn the secret incantation to reset the printer, you must fax proof of purchase to them.

But what if your fax machine is your malfunctioning Canon device?

So, did you finally manage to reset your imageCLASS? I have a MF4150 and the same issue. –  Nicolas Oct 10 '11 at 14:39
    
No. I forget the workaround, and I no longer work where the printer is. Sorry. –  benzado Oct 10 '11 at 21:08

I had the same issue with an imageCLASS 5950dw and jumped through their proof of purchase hoops.

To reset (the 5950 anyway), menu - 2 - 8 - menu gets you to the service menu, then do copier - function - clear - all to fully reset the machine.
