Network Problems

Return to Overview


Unable to print from a TCP/IP network.

The printer port name is not displayed in [Print to the following port(s)].

The machine automatically connects to a destination other than the intended destination via its dial-up access (when a dial-up router is connected to the network).

Detailed information concerning the machine cannot be set or browsed using the Remote UI or utility.

Unable to print from a TCP/IP network.

Are the machine and cable properly connected?

Check that the machine is connected to the network using the proper cable, then restart the machine. (See "Set Up Network Connection," in the Starter Guide.)

Is the TCP/IP network properly set up?

Make sure the IP addresses are properly set up. If the IP addresses are set using DHCP, BOOTP, or RARP, make sure they are operating.

Is the computer that is printing properly set up?

Make sure the proper printer driver is installed. (See "Set Up Computers and Software," in the Starter Guide.)

Make sure the correct machine is set as the output destination for the computer that is printing in [Printers and Faxes] or Print Manager.

Is the name of the file being printed too long?

Rename the file with a shorter name. Normally LPR (or the Microsoft TCP/IP Printer, if you are using Windows 2000/XP/Vista/7/Server 2003/Server 2008) sends jobs either under the name of the application software used for printing or the file name. However, a job name longer than 255 bytes cannot be sent to the machine.

The printer port name is not displayed in [Print to the following port(s)].

Are the machine and cable properly connected?

Check that the machine is connected to the network using the proper cable, then restart the machine. (See "Set Up Network Connection," in the Starter Guide.)

Is the computer that is printing properly set up?

Make sure the proper printer driver is installed. (See "Set Up Computers and Software," in the Starter Guide.)

Make sure the correct machine is set as the output destination for the computer that is printing in [Printers and Faxes] or [Printers].

The machine automatically connects to a destination other than the intended destination via its dial-up access (when a dial-up router is connected to the network).

Does the dial-up router send packets via broadcast?

If the dial-up router does not need to send packets via broadcast, change the router settings to ensure that it sends packets via a method other than broadcast. If the dial-up router has to send packets via broadcast, check that the settings are correct.

Dose the file or mail server's host name or IP address set on the machine exist on the network?

Check that the file or mail server's host name or IP address set on the machine is correct.

Does the DNS server exist on an external network?

If you attempt to access a device on the network to which the machine is connected, with the DNS server on an external network, set the destination using an IP address, not a host name.

Is the device's information set on the DNS server on the network to which the machine is connected correct?

If information about a device on an external network is set on the DNS server on the network to which the machine is connected, check the settings.

Detailed information concerning the machine cannot be set or browsed using the Remote UI or utility.

Are the settings for <SET IP ADD RANGE> correct?

If the settings for [IP Address Range Settings] do not permit the IP address of a computer on which the Remote UI or utility is used, you cannot set the machine setting items or browse information on the machine. Check the settings for <SET IP ADD RANGE>. (See "Controlling Machine Access Using IPv4 addresses" or "Controlling Machine Access Using IPv6 addresses.")

Is <USE SNMP> is set to <OFF>?

Set <USE SNMP> to <ON>. (See "Setting SNMP.")

Does the SNMP community name match?

If you use an SNMP community name different from the one stored in the machine to access the machine from a utility, the utility will not detect the machine. In this case, check the SNMP community name. (See "Setting SNMP.")
