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 "Connect the Machine to a Network (Set the Machine for Network Usage).")

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 "Installing Software.")

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) 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.

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 "Connect the Machine to a Network (Set the Machine for Network Usage).")

Is the computer that is printing properly set up?

Does the dial-up router send packets via broadcast?

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

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 "IP Address Range Settings (IPv4 Settings)" or "IP Address Range Settings (IPv6 Settings).")

Are the settings for <PERMIT RX MAC ADD> correct?

If the MAC address of a computer specified in <PERMIT RX MAC ADD> is not correct, you cannot set the machine setting items or browse information on the machine. Check the settings for <PERMIT RX MAC ADD>. (See "RX MAC Address Settings.")

Is <USE SNMP> or <DEDICATED PORT> is to <OFF>?

Set <USE SNMP> and <DEDICATED PORT> to <ON>. (See "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 "SNMP.")

Are File sharing settings for the shared folder correct?

Check the following settings:

• On the computer you are using, go into Windows Explorer → double-click [Entire Network] → check that the computer you want to share is listed there. You can also check for the computer as follows: On the [Start] menu, point to [Find] → [Computer] → enter the name of the computer you want to share → check that the computer is on the network.

• If the computer you want to share is listed, doubleclick its icon to see whether the shared name of the folder you want to share is listed.

• If the shared name does not appear, see "Configuring a Shared Folder." and then check the shared folder settings.

Is an error message or code displayed on the LCD of the machine?
