Scanner can't access a shared folder on 10.11.5

I shared out a folder on OSX 10.11.5. The permissions are correct. I can access the share from a Windows machine (it asks for credentials and is REALLY slow to show files) but when I try to scan a document to the share it errors out every time. This worked until recently. I am 100% sure the credentials on the scanner are correct.


Just so there's no confusion I set up an account on my networked scanner (which is on the same subnet) with the same credentials as those of a user on the OSX machine. The share is visible and writable from a Windows machine. When I scan from the scanner (A Konika Minolta Bizhub) it says "Error: cannot connect to server." This is not a login/permissions issue as when I change the credentials I get a different error message.


Any ideas?

iMac, OS X El Capitan (10.11.5)

So you are probably aware that Apple changed the version of SMB being used back in 10.7 and later and this resulted in many MFDs no longer being able to scan to a share on the Mac using SMB. I know that KM released a patch for some of their machines that allowed this to work again. Since you mention it working recently, I have assumed that this was to a Mac running OS X 10.11.x. Is this correct?


If yes, then on the KM, do you have the ability to browse to the Mac share rather than use the address book entry? If you can, then using that function you should see the Mac and when you select it you should get a prompt to authenticate. If you then enter the account name set on the Mac, which has to be enabled via System Preferences > Sharing > File Sharing > Options > Windows File Sharing, and then the password, is the shared folder displayed? Or do you get an error at this point, or when you first select the Mac?

Hi PAHU


I was not aware that Apple changed SMB in 10.7. Thanks for letting me know. To answer one of your questions, yes this is to a Mac running 10.11.5.


Browsing to a Mac share on the KM. I'm not sure what you mean by that but I think you mean Direct Input instead of using the Address Book. When I use Direct Input I enter the name of the server and tap Check Connection. I get SMB Host Confirmed. See Image

I then enter the folder it's scanning to and click Check Connection. Again, I get the same SMB Host Confirmed message. So I enter the username of an administrator on the Mac and tap Check Connection. Same message, all is good. I enter the password for that user and I get "Error, Cannot connect to network"


I do have the Windows File Sharing option selected for the user and I unchecked it, entered the password, checked it and entered the password again just to be sure. It seems like the scanner is not passing the credentials in the way that the Mac wants them.


And for good measure here's the Job Error. Notice the Error Dets on the upper right.

In you opening post you stated that this was working until recently. What changed to the Mac in that time? For example, was the Mac running 10.11.4 and the scanning was working and then you updated to 10.11.5 and it stopped scanning?

Pretty much what I meant. On the Canon MFDs that I support there is a feature that lets you browse the local network and select the desired computer from a list. When you select that computer, you are then prompted to authenticate before you see the share. In the case of the Canon MFDs that no longer support SMB scanning to OS X, selecting a Mac running 10.7 or later just results in an error after you enter the Mac account/password.

This would suggest that the KM cannot authenticate to OS X, the same issue as some Canon's. But if this was recently working to the Mac running OS X 10.11.5 then it's not the same limitation as the Canon, which has not worked since 10.7, and something else has changed, most likely in the copier since the Windows PC can connect to the share.


For your information, for Canon MFD owners that want to scan to a shared folder on a Mac, we enable FTP on the Mac and then use that as the communication protocol instead of SMB. If the KM Bizhub can do the same and you would like to try it, the instructions are below.


Since the FTP service is not a user selectable option in the System Preferences > Sharing > File Sharing pane of 10.11 you have to enable FTP via Terminal. You can type (or copy and paste) the following into Terminal;


sudo -s launchctl load -w /System/Library/LaunchDaemons/ftp.plist


Then press Return. You then need to enter the Mac's admin password and press Return again.


With FTP enabled on the Mac, you can then create an address book entry in the MFD using the following settings;


Protocol: FTP

Hostname: IP address of Mac

File Path: path to folder from Home folder

User Name: Full user name of the account owner of the destination folder

Password: Password for the account above


An example of the copier address book configuration to a Mac with an IP address of 172.17.4.33 and a user of Peter Hall and a folder called Scans located on his Desktop would be;


Protocol: FTP

Hostname: 172.17.4.33

File Path: Desktop/Scans

User name: Peter Hall

Password: password

Where and how can your mfc browse the network? On mine i never have seen such a feature.

It is a mfc j 5910 dw, firmware release says j

The Canon MFD's I am referring to are large office devices known as imageRUNNER ADVANCE. Via the touch panel you can select to Scan To File and this menu provides a browse function, that lets you select the Workgroup/Domain and then the computer. Here is a link to the online user guide that shows that function.

Ahh yes, I am quite familiar with the IRC5045. Unfortunately I don't believe this function exists in the Bizhub.

I wish I could tell you what changed. It's a customer's Mac, not my own. I'm totally guessing here but I think he was on 10.11.something previously and updated to 10.11.5 either on purpose or automagically. As you stated this is the same authentication issue as with your Canon machines. I'm calling this as an Apple issue which there's no current fix for. I'll try contacting KM to see if they have any ideas but I'm not hopeful.


In regards to a fix. Thanks for the FTP idea. I'm going to keep that handy for the future. While I'm certain that would work I've implemented another workaround. Since there are multiple Windows machines in the environment I've shared out a folder on one of them and set the scanner to send to that folder. I set up a smb:// alias on the user's Mac to point to this folder. So far so good however it kinda stinks he can't scan to his machine anymore.

I looked up the manual for your Brother MFC. It looks like your device supports scanning to FTP. http://www.manualslib.com/manual/457835/Brother-Mfc-J425w.html?page=226#manual


Maybe setting up FTP on the Mac like PAHU suggested would solve your issue.I know the URL says MFC J425w but if you look at the manual on that page it's definitely for a MFC-J5910DW.

FTP is the way to go.

Some updates will close FTP services. To re-enable FTP run:

sudo -s launchctl load -w /System/Library/LaunchDaemons/ftp.plist


Once FTP is up and running you will have the possibility of two errors.

Path or authentication. For this reason I always create the share on the mac hd IE /Sharename
