Cannot connect to the email server
●
Make sure the SMTP or LDAP server name is correct. Check this setting with your system administrator
or Internet Service Provider.
●
If the printer cannot establish a secure connection to the SMTP or LDAP server, try without the secure
connection or try a dierent server or port. Check this setting with your system administrator or Internet
Service Provider.
●
If the SMTP or LDAP server requires authentication, make sure a valid user name and password are used.
●
If the SMTP or LDAP server uses an authentication method that is not supported, try a dierent server.
Check this setting with your system administrator or Internet Service Provider.
Validate the SMTP gateway (Windows)
1. Open an MS-DOS command prompt: click Start, click Run, type cmd, and then press the Enter key.
2. In the command prompt window, type telnet followed by the SMTP gateway address and then the
number 25, which is the port over which the printer is communicating. For example, type telnet
123.123.123.123 25 where "123.123.123.123" represents the SMTP gateway address.
3. Press the Enter key. If the SMTP gateway address is not valid, the response contains the message Could
not open connection to the host on port 25: Connect Failed.
4. If the SMTP gateway address is not valid, contact the network administrator.
Validate the LDAP gateway (Windows)
1. Open Windows Explorer. In the address bar, type LDAP:// immediately followed by the LDAP gateway
address. For example, type LDAP://12.12.12.12 where "12.12.12.12" represents the LDAP
gateway address.
2. Press the Enter key. If the LDAP gateway address is valid, the Find People dialog box opens.
3. If the LDAP gateway address is not valid, contact the network administrator.
