HP printer cannot scan to network folder after upgrading to OS 5

After upgrading my PR4100 from OS 3 to OS 5, my HP LaserJet 400 MFP M425dn can no longer scan documents to a network folder on the PR4100.

When I entered into the LaserJet Scan configuration GUI page and selected the Test option, the response was “The test was unsuccessful. Try again.”

On the configuration page, the network address is \nas1\cds\scanned\Scanned PDF

I am able to access this network folder from Windows 10, macOS 10.15 and Ubuntu 18.04 but not from the HP printer.

The network path hasn’t changed. Any ideas on a solution?

Same here, just upgraded to OS 5, can’t scan to network folder on my EX4100 from HP Color LaserJet MFP M477fdw. Please help!

Hi, try to change smb version in network settings to SMB1, SMB2, SMB3.

Thanks Corwin!

Your suggestion to change the SMB Protocol settings to “SMB 1, SMB 2, SMB 3” (it was SMB 3 after OS 5 upgrade) resolved the HP printer issue of not being able to scan to the network folder.

Very much appreciate your and the WD communities help!

Hi Larry, just checked HP site (link below), M477fdw should support SMB2. If you are willing to try to change settings again try to set it to SMB2 SMB3 (hope this option is there, did not check), SMB1 has some security issues and should not be used unless neccessary.


Hi Corwin,

I was adventurous and changed the OS 5 SMB protocol settings to “SMB 2, SMB 3” and re-ran the HP Printer GUI network folder access test. It worked!

So I’m keeping the “SMB 2, SMB 3” setting for my WD file server.

Thanks for being curious and checking out the HP site.

Hi Corwin,

I did the same as Larryhuang, set to SMB 2, SMB3 and it worked for me. Wow, I spent few hours last night after the upgrade hacking shares, passwords, rebooting etc and could not fix it. You saved me!

Hello All,

I am a bit new to this level of networking, but I am trying to learn.
I have a printer on one interface that needs to be accessible from the other two.
My product is a FortiWiFi 60D, version 5.6.12.
My config is:
wan1 = connection between small office and internet
physical LAN = 10.10.79.X
wifi1 = device is located here 10.10.80.X
wifi2 = 10.10.180.X
wifi3 = 10.10.81.X (Guest)
I can ping the printer from LAN, wifi1, and wifi2, but it doesn’t show up in AirPrint like it used to (prior to FortiWifi 60D being installed) which makes it difficult for the Apple products to connect to it and print.
In ““Addresses”” under ““Policy & Objects”” I have it defined as:
““Canon Printer””, subnet,, interface = ““any””, Show in Address List = enabled, Static Route Configuration disabled.
In IP4Policy the very first policy I have is:
Name: Printer # 1 Policy
Incoming Interface: physical LAN, wifi1, and wifi2
Outgoing Interface: wifi1
Source: physical LAN, wifi1, and wifi2
Destination: ““Canon Printer””
Schedule: Always
Service: ALL
Action: Accept
NAT = Enabled
IP Pool Config: Use Outgoing Interface Address
None of the Security Profiles are Enabled
Log Allowed Traffic: Enabled with ““All Sessions””
The policy is Enabled.

Does anyone have any idea what I am missing? I have been messing around with this for a couple of days and the hair loss is getting to be a bit much.

Try adjusting the SMB & NTLM to older version and see if that’s the problem. Some older network devices (like Sonos below) may still require them. Could be the same problem.

Custom T-shirts are sometimes cheap and sometimes expensive, but they always make great gifts. They’re a fun way to extend your company’s reach, either because you bought the first run or they’re like-new, and you want to make sure they stay that way. My favorite method for purchasing custom t-shirts has always been through a website, which allows me to order print designs through them and have them printed on an actual shirt in minutes. This is why I think people should try to figure out how they can get a print on their shirts in an affordable fashion. It’s easily affordable for someone who isn’t sure if they want to pay for the image itself or if they want it printed on something else (such as an airfare invitation or a coffee cup). You may follow the official website.
