Check the following points

If the problem still persists, check each item in Before You Contact the Scanner Service Provider first, then contact the distributor/dealer where you purchased this product. Refer to the contact information in the Contact List if supplied with this product, or refer to the contact information in the Contact for Inquiries section if provided in Safety Precautions supplied with this product, and then make an inquiry.

Has the connection to the NTP server timed out?

Solution

The connection to the NTP server may time out due to heavy access to the server.

Wait a while, then try to connect to the NTP server again by following the below procedure:

  1. On the touch screen, press Settings → [Scanner Settings] → [Network] → [DirectScan] → [NTP Server].

  2. Press the [Sync Time] button

HINT

The IP address of the scanner can also be checked in fi Series Network Settings.

For details, refer to Network Settings (fi Series Network Settings).

Is the IP address of the scanner correct?

Solution

Check the IP address of the scanner in the following procedure:

  1. On the touch screen, press Settings → [Scanner Settings] → [Network] → [Wired LAN] → [IP Address (IPv4)] or [IP Address (IPv6)].

  2. On the [IP Address (IPv4)] or [IP Address (IPv6)] screen, check the setting items for the following.

    When specifying an IP address manually, specify the correct IP address.

    When setting the IP address automatically, check whether the DHCP server functions normally.

    Even when the DHCP server functions normally, an IP address may not be assigned correctly depending on the settings for the DHCP server. Check the operation status and the settings for the DHCP server.

HINT

The IP address of the scanner can also be checked in fi Series Network Settings.

For details, refer to Network Settings (fi Series Network Settings).

Is the IP address of the scanner used for other communication devices?

Solution

If there are multiple communication devices using the same IP address on the same network, communication may fail. Avoid duplicates in IP addresses.

HINT

If there is an IP address conflict, a notification appears on the touch screen.

Can the scanner and NTP server communicate with one another?

Solution

Start up the command prompt on a computer in the same subnetwork as the scanner, then specify the IP address of the NTP server using the tracert command to check communication between the scanner and NTP server.

If there is a communication issue, check the following:

  • Are the cables properly connected to the network device (switch, hub, router, etc.)?

  • When MAC address filtering is set for the network device (switch, hub, router, etc.), set the filter to approve the MAC address of the scanner.

    The MAC address of the scanner can be checked by following the below procedure:

    Settings → [Scanner Information] → [MAC Address] under [Network]

  • When the protocol filter function is set for the network device (switch, hub, router, etc.), enable the UDP protocol to be used for communication.

  • When communication between connected devices is prohibited by the network device (switch, hub, router, etc.) (for example, due to the network isolation function), enable the communication.

For the settings on the network device, refer to the manual of your network device.

Is the NTP server functioning normally?

Solution

In some cases, the NTP server will not respond.

When manually specifying the NTP server, check whether the NTP server is functioning normally.

Is there a firewall device between the scanner and the server?

Solution

Check that the access from the scanner is not prohibited by the firewall device.

Did you turn the scanner off then back on?

Solution

Turn the scanner off then back on.

Wait for at least 5 seconds after turning off the scanner before turning it back on.

For details, refer to How to Turn the Power ON.
