Configuring the WSD scan environment

Setting flow

WSD (Web Service for Device) is a function to search for a WSD-compatible device on the network.

WSD Scan enables you to instruct scanning from a computer and import the original data without configuring tiresome environmental settings. This option is only compatible with Windows computers.

HTTP is used for communication between this machine and the computer. Use SSL to encrypt a communication between the this machine and the computer; you can send a file more securely.

When using the WSD scan, follow the below procedure to configure the settings.

  1. Configuring network settings of this machine ( [Network Settings] )

  2. Configuring basic settings for WSD Scan ( [Configuring basic settings for WSD Scan] )

  3. Configuring settings to suit your environment

Configuring basic settings for WSD Scan

Configure the settings to use the WSD Scan function.

  1. Select [Network] - [DPWS Settings] - [DPWS Common Settings] in administrator mode of Web Connection (or in [Utility] - [Administrator] of this machine), and configure the following settings.

    Setting

    Description

    [Friendly Name]

    Enter the name of this machine to be displayed when being searched using the Web service from the computer (using up to 62 characters).

    [Publication Service]

    When using this machine in either one of the following environments, set this option to ON (default: ON).

    • Environment where NetBIOS is disabled on Windows computer

    • Environment constructed so that only communications using IPv6 are allowed

    Up to 512 destinations can be detected in Publication Service (including detection counts by NetBIOS).

  2. Select [Network] - [DPWS Settings] - [Scanner Settings] in administrator mode of Web Connection (or in [Utility] - [Administrator] of this machine), and configure the following settings.

    Setting

    Description

    [Scan Function]

    When using the WSD scan function, set this option to ON (default: OFF).

    [Scanner Name]

    Enter the name of this machine when using it as the WSD scanner (using up to 63 characters).

    [Scanner Location]

    Enter a scanner location if necessary (using up to 63 characters).

    [Scanner Information]

    Enter scanner information if necessary (using up to 63 characters).

    [Connection Timeout]

    If necessary, change the time-out time to limit a communication with the computer (default: [120] sec.).

Using a proxy server

Configure settings to establish communications in the environment where the multicast communication is restricted using the discovery proxy defined by WS-Discovery. Configure the setting if your environment requires the discovery proxy server.

In normal circumstances, the computer must be connected at a location where multicast communication is available for this machine. However, installing the discovery proxy server at a location where unicast communication is available for this machine enables communications even in environment with multicast communication restricted.

Select [Network] - [DPWS Settings] - [DPWS Extension Settings] in administrator mode of Web Connection (or in [Utility] - [Administrator] of this machine), and configure the following settings.

Setting

Description

[Enable Proxy]

When using discovery proxy, set this option to ON (default: OFF).

[Proxy1] to [Proxy3]

Register the discovery proxy server.

  • [Proxy Server Address]: Enter the discovery proxy server address. Use one of the following formats.
    Example to enter the host name: "host.example.com"
    Example to enter the IP address (IPv4): "192.168.1.1"
    Example to enter the IP address (IPv6): "fe80::220:6bff:fe10:2f16"

  • [File Path]: Enter the service name at the path of the URL where the WS-Discovery service is published in the discovery proxy server (using up to 255 characters).

  • [Enable SSL]: When using SSL communications, set this option to ON (default: OFF).

  • [Proxy Server Port Number]: If necessary, change the port number of the discovery proxy server (default: [80]/[443] (in use of SSL)).

Using SSL communication

Configure settings to encrypt communications between this machine and the computer using SSL.

To encrypt SSL communication between this machine and the computer, you must set the bidirectional SSL communication between them. Before starting this procedure, confirm the following.

  • Name resolution must have been performed in the DNS server.

  • If the certificate of this machine is not the one issued by the Certificate Authority (CA), you must register the certificate of this machine in [Trusted Root Certification Authorities] of the computer.

  • Create a certificate in the computer side in advance, and associate it with the TCP/IP communication port (default port number: 5358).

Select [Network] - [DPWS Settings] - [DPWS Common Settings] in administrator mode of Web Connection (or in [Utility] - [Administrator] of this machine), and configure the following settings.

Setting

Description

[SSL Setting]

When using SSL communications, set this option to ON (default: OFF).

[Certificate Verification Level Settings]

To validate the certificate during SSL communication, select items to be verified.

  • [Expiration Date]: Confirm whether the certificate is within the validity period (default: ON).

  • [Key Usage]: Confirm whether the certificate is used according to the intended purpose approved by the certificate issuer (default: OFF).

  • [Chain]: Confirm whether there is a problem in the certificate chain (certificate path) (default: OFF). The chain is validated by referencing the external certificates managed on this machine.

  • [Expiration Date Confirmation]: Confirm whether the certificate has expired (default: OFF). The expiration date confirmation is performed in the order of OCSP (Online Certificate Status Protocol) service, and CRL (Certificate Revocation List).

Tips

  • In Windows 8.1/10, a communication using the Web service cannot be encrypted using SSL.
