If the Machine Cannot Be Operated

Cannot perform the following:

• Print with the printer driver

• Connect with the TWAIN driver

• Send or print with the LAN-Fax driver

User authentication has been refused.

Check the user name and login name with the administrator of the network in use if using Windows authentication or LDAP authentication.

Confirm with the user administrator if using Basic authentication.

Cannot perform the following:

• Print with the printer driver

• Connect with the TWAIN driver

• Send or print with the LAN-Fax driver

The encryption key specified in the driver does not match the machine's driver encryption key.

Specify the driver encryption key registered in the machine.

For details, see Specifying a Driver Encryption Key.

Cannot connect with the TWAIN driver.

The SNMPv3 account, password, and encryption algorithm do not match the settings specified on this machine.

Specify the account, password and the encryption algorithm of SNMPv3 registered in the machine using network connection tools.

Cannot perform authentication using the TWAIN driver.

Another user is logged in to the machine.

Wait for the user to log out.

Cannot perform authentication using the TWAIN driver.

Authentication is taking time because of the operating conditions.

Make sure the LDAP server setting is correct.

Make sure the network settings are correct.

Cannot perform authentication using the TWAIN driver.

Authentication is not possible while the machine is editing the Address Book data.

Wait until editing of the Address Book data is complete.

After starting "User Management Tool" or "Address Management Tool" in Device Manager NX and entering the correct login user name and password, a message that an incorrect password has been entered appears.

"Driver Encryption Key:Encryption Strength" is not set correctly. Alternatively, "SSL/TLS" has been enabled although the required certificate is not installed on the computer.

Set "Driver Encryption Key:Encryption Strength" to [Simple Encryption]. Alternatively, enable "SSL/TLS", install the server certificate in the machine, and then install the certificate in the computer.

For details, see Specifying the Extended Security Functions and Configuring SSL/TLS Settings.

Cannot log out when using the copying or scanner functions.

The original has not been scanned completely.

When the original has been scanned completely, press [], remove the original, and then log out.

"Prg. Dest." does not appear on the fax or scanner screen for specifying destinations.

"Restrict Adding of User Destinations (Fax)" and/or "Restrict Adding of User Destinations (Scanner)" is set to [On] under "Extended Security", so only the user administrator can register destinations in the Address Book on the fax or scanner screen.

Registration must be performed by the user administrator.

Cannot send e-mail from the scanner.

Similarly:

• Cannot select an address.

• Cannot specify a signature.

• Cannot store data in a media.

The following are possible causes:

• The validity period of the user certificate (destination certificate) has expired.

• The validity period of the device certificate (S/MIME) has expired.

• The device certificate (S/MIME) does not exist or is invalid.

• The validity period of the device certificate (PDF with digital signature or PDF/A with digital signature) has expired.

• The device certificate (PDF with digital signature or PDF/A with digital signature) does not exist or is invalid.

• The administrator's e-mail address is incorrect.

• Install a user certificate (destination certificate).

  You can install a user certificate (destination certificate) from the Web Image Monitor address book. The user certificate (destination certificate) itself must be prepared in advance.

• Install a device certificate for S/MIME.

• Install a device certificate for PDF with digital signature or PDF/A with digital signature.

  For details, see Protecting Communication Paths via a Device Certificate.

• Specify the administrator's e-mail address.

  For details, see "File Transfer", Connecting the Machine/System Settings.

Cannot transfer faxed documents.

Similarly:

• Cannot select an address.

• Cannot specify a signature.

The following are possible causes:

• The validity period of the user certificate (destination certificate) has expired.

• The validity period of the device certificate (S/MIME) has expired.

• The device certificate (S/MIME) does not exist or is invalid.

• The validity period of the device certificate (PDF with digital signature or PDF/A with digital signature) has expired.

• The device certificate (PDF with digital signature or PDF/A with digital signature) does not exist or is invalid.

• The administrator's e-mail address is incorrect.

• Install a user certificate (destination certificate).

  You can install a user certificate (destination certificate) from the Web Image Monitor address book. The user certificate (destination certificate) itself must be prepared in advance.

• Install a device certificate for PDF with digital signature or PDF/A with digital signature.

  For details, see Protecting Communication Paths via a Device Certificate.

• Specify the administrator's e-mail address.

User authentication is disabled, yet stored files do not appear.

User authentication might have been disabled without "All Users" being selected for user access to stored files.

Enable user authentication again, and select [All Users] as the access permission setting of the files you want to display.

For details, see Managing Stored Files.

User authentication is disabled, yet destinations specified using the machine do not appear.

User authentication might have been disabled without "All Users" being selected for "Protect Destination".

Enable user authentication again, and select [All Users] as the access permission setting of the destinations you want to display.

For details, see Protecting the Address Book.

Cannot print when user authentication has been enabled.

User authentication may not be specified in the printer driver.

Specify user authentication in the printer driver. For details, see the printer driver Help.

[Finish Job and Limit] is selected in "Machine action when limit is reached", but the current job is canceled before it is processed.

Depending on the application you are using, the machine might recognize a job as multiple jobs, canceling the job before it is processed.

Reset the print volume use setting for the user by, for example, clearing the print volume use counter, and then perform printing again.

For details, see Resetting Print Volume Use Counters.

If you try to interrupt a job while copying or scanning, an authentication screen appears.

With this machine, you can log out while copying or scanning. If you try to interrupt copying or scanning after logging out, an authentication screen appears.

Only the user who executed a copying or scanning job can interrupt it.

Wait until the job has completed or check with the user who executed the job.

The machine administrator can delete jobs.

After executing "Encrypt User Custom Settings & Address Book", the "Exit" message does not appear despite waiting a long time.

Authentication may be taking time because a large number of items are registered in the address book. Alternatively, a file may be corrupt or the hard disk may be faulty.

If the screen has still not updated even though the "File System Data Only" time specified in accordance with Encrypting Data on the Hard Disk has elapsed, contact your service representative.
