Overview

The SMB Send is a function that transmits original data scanned on this machine to a shared folder in a specified computer. The shared folder is shared using the SMB (Server Message Block) protocol.

If the WINS server is installed to resolve the name, register it.

Enabling the direct hosting SMB service allows communications using the IP address (IPv4/IPv6) or host name. Enabling this service allows you to use the SMB Send function even in the IPv6 environment.

Using LLMNR (Link-local Multicast Name Resolution) enables you to resolve the name even in an environment with no DNS server. This function is supported by the computer loaded with Windows Vista or later (Windows Vista/7/8.1/10/Server 2008/Server 2008 R2/Server 2012/Server 2012 R2). It is useful to resolve the name in the IPv6 environment.

When using the SMB Send function, follow the below procedure to configure the settings.

Configure settings for connecting to the network such as setting of the IP address of this machine
For details on configuring the setting, refer to [Configuring network environment settings] .
Configure basic settings for the SMB transmission
For details on configuring the setting, refer to [Configuring basic settings for the SMB transmission] .

Set the following options according to your environment

Reference

If user authentication by Active Directory is installed, the Scan to Home function is available, which you can easily send data to a shared folder on the server or that on the login user's computer. For details, refer to [Sending to Your Computer (Scan to Home)] .
If the user authentication is installed, using the user authentication information (login name and password) as SMB destination authentication information (host name and password) avoids the problem of having to specify SMB destination authentication information, allowing construction of a single sign-on environment for SMB transmission. For details, refer to [Constructing a single sign-on environment for the SMB transmission] .

Tips

To use the SMB transmission function in IPv6 environment, you need to enable the direct hosting SMB service.
In the IPv4 environment, the SMB transmission function can be used regardless of whether or not the direct hosting SMB service is enabled.
If the direct hosting SMB service is enabled, the system operates as shown below (common to IPv4 and IPv6 environments).
A destination computer can be specified using the IP address (IPv4 or IPv6).
If a destination computer is specified using the host name or computer name (NetBIOS name), name resolution is performed in the order of DNS, LLMNR, and NetBIOS (port 137 of a destination computer).
Connection is attempted to port 445 and port 139 of a destination computer in that order, and transmission is carried out.
If the direct hosting SMB service is disabled, the system operates as shown below.
A destination computer can be specified using the IP address (IPv4 only).
If a destination computer is specified using the computer name (NetBIOS name) or host name, name resolution is performed in the order of NetBIOS (port 137 of a destination computer) and DNS.
A connection with port 139 of a destination computer is established, and a transmission is carried out.
To specify a destination computer using the host name, configure the appropriate machine settings and prepare the appropriate environment so that name resolution can be performed with DNS or LLMNR.
To perform name resolution with DNS, a destination computer can be specified with "Host Name (example: host1)" or "FQDN (example: host1.test.local)".
To perform name resolution with LLMNR, a destination computer can be specified only with "Host Name (example: host1)".

Configuring basic settings for the SMB transmission

Enable the SMB Send function. Also, specify the authentication method for SMB transmission, and select whether to enable the SMB signature.

In the administrator mode, select [Network] - [SMB Setting] - [Client Setting], then configure the following settings.

Settings	Description
[SMB TX Setting]	Select [ON] to use the SMB transmission function. [ON] is specified by default.
[SMB Authentication Setting]	Select an authentication method for SMB transmission according to your environment. [NTLM v1]/[NTLM v2]/[NTLM v1/v2]: Select this to use the function in the NT domain environment. If you select [NTLM v1/v2], NTLMv1 authentication is performed when NTLMv2 authentication fails. [Kerberos]: Select this to use the function in the Active Directory domain environment. [Kerberos/NTLM v1/v2]: Select this to use the function in an environment both the Active Directory domain and NT domain exist in. NTLMv2 authentication is performed when Kerberos authentication fails, and NTLMv1 authentication is performed when NTLMv2 authentication fails. [NTLM v1] is specified by default.
[SMB security Signature Setting]	Select whether to enable the SMB signature of this machine to suit your environment. [Disable]: Disables the SMB signature of this machine. [When Requested]: Enables the SMB signature of this machine (client) only when the SMB signature is requested from the server side. If the SMB signature is not requested from the server side, operations are performed while the SMB signature of this machine (client) remains disabled, and a connection is possible even when the SMB signature in the server side is disabled. [Required]: Enables the SMB signature of this machine. To establish a connection, the SMB signature is also required in the server side. If the SMB signature in the server side is disabled, it will not be possible to make a connection. [When Requested] is specified by default.

Settings

Description

[SMB TX Setting]

Select [ON] to use the SMB transmission function.

[ON] is specified by default.

[SMB Authentication Setting]

Select an authentication method for SMB transmission according to your environment.

[NTLM v1]/[NTLM v2]/[NTLM v1/v2]: Select this to use the function in the NT domain environment. If you select [NTLM v1/v2], NTLMv1 authentication is performed when NTLMv2 authentication fails.
[Kerberos]: Select this to use the function in the Active Directory domain environment.
[Kerberos/NTLM v1/v2]: Select this to use the function in an environment both the Active Directory domain and NT domain exist in. NTLMv2 authentication is performed when Kerberos authentication fails, and NTLMv1 authentication is performed when NTLMv2 authentication fails.

[NTLM v1] is specified by default.

[SMB security Signature Setting]

Select whether to enable the SMB signature of this machine to suit your environment.

[Disable]: Disables the SMB signature of this machine.
[When Requested]: Enables the SMB signature of this machine (client) only when the SMB signature is requested from the server side. If the SMB signature is not requested from the server side, operations are performed while the SMB signature of this machine (client) remains disabled, and a connection is possible even when the SMB signature in the server side is disabled.
[Required]: Enables the SMB signature of this machine. To establish a connection, the SMB signature is also required in the server side. If the SMB signature in the server side is disabled, it will not be possible to make a connection.

Tips

In Mac OS, set [SMB Authentication Setting] to [NTLM v1/v2].
In Mac OS, the direct hosting SMB service must be enabled (default: [ON]). For details, refer to [Using the direct hosting SMB service] .

[WINS Server Address1] to [WINS Server Address2]	Enter the WINS server address. This item is necessary when you do not automatically obtain the WINS server address using the DHCP. Use the following entry formats. Example of entry: "192.168.1.1"
[Node Type Setting]	Select the name resolution method. [B Node]: Query by broadcast [P Node]: Query the WINS server [M Node]: Query by broadcast, and then query the WINS server [H Node]: Query the WINS server, and then query by broadcast [H Node] is specified by default.

Using the direct hosting SMB service

Enabling the direct hosting SMB service allows you to specify the destination using the IP address (IPv4/IPv6) or host name.
