Check that the machine is connected to the network using the proper cable, then restart the machine. (See "Set up Network Connection.")
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.
Confirm that the IPv4 addresses are properly set up. If the IPv4 addresses were set using DHCP, BOOTP, or RARP, confirm that they are operating.
Confirm that the IPv6 addresses are properly set up. After checking the settings of the router, set Use Stateless Address to [On] to confirm whether you can obtain an address. If the IPv6 addresses were set using DHCPv6, confirm that DHCPv6 is operating. Your computer may not be able to recognize the machine even though the IP address settings are appropriate. This problem may be resolved by delaying the startup of network communications for the machine. (See "Setting Startup Time.")
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) 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.
Is the IP address of the computer from which data (print/fax/I-fax job) is to be sent to the machine not permitted by the IP Address Range Settings on the IPv4 or IPv6 Settings screen?
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 have 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 <IP Address Range Settings> correct?
Are the settings for <Receiving MAC Address> correct?
If the MAC address of a computer specified in <Receiving MAC Address> is not correct, you cannot set the machine setting items or browse information on the machine. Check the settings for <Receive MAC Address Set.>. (See "Limiting the Machine Access to a Certain MAC Address.")
Is <Use SNMP> or <Dedicated Port Settings> is to <Off>?
Set <Use SNMP> and <Dedicated Port Settings> to <On>. (See "Setting SNMP.")
Does the SNMP community name match?
If an SNMP community name different from the one stored in the machine is used to access the machine from a utility, the utility will not detect the machine. If this happens, check the SNMP community name. (See "Setting SNMP.")
Unable to send data/share files (FTP).
Is the FTP server set correctly?
Check the following (if you are using Windows, perform these from the MS-DOS prompt):
Example using UNIX, where the FTP server has the IP address:
U:>ftp 192.168.1.195 *Connect to server Connected to 192.168.37.195.220 canmfs FTP server (UNIX(r) System V Release 4.0) ready.
User (192.168.37.195:(none)): user_name *User login
331 Password required for user_name.
Password: *Enter password
230 User user_name logged in.
ftp> cd /export/share *Move to data destination directory
250 CWD command successful.
ftp> bin *Set data transfer type (binary)
200 Type set to I.
ftp> put sample.tif *Set transfer file name for verification
ftp> bye *Cut off server connection
If, after checking the above, the file sharing still does not operate normally, consult the network administrator for the environment you are using.
Is the machine's address [User] setting correct?
Ensure that the machine's address [User] setting does
not contain spaces after the user name.
Was the machine turned OFF while sending data to the FTP server (if a Windows 2000/XP/Server 2003/Vista FTP server is being used)?
If power to the machine is turned OFF while data is being sent to the FTP server, the FTP server may hold the data in a writing-in-progress state. Therefore, this data cannot be overwritten even when the machine reconnects and sends the same data again. Stop the FTP server temporarily and delete the held data, so that it can be sent again.
Unable to send data/share files (Windows File Sharing).
Are the 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, double-click its icon to see whether the shared name of the folder you want to share is listed.
If the name of the shared folder does not appear, see "Setting Shared Folder" and check the shared folder settings.
Is an error message or code displayed on the display of the machine?
After confirming the error message, see "Error Messages" and perform the necessary operations according to the error message displayed.
