Xerox AltaLink C8170 003-754 Error: Solution

The Xerox AltaLink C8170 error 003-754 signals a failure in the authentication process against a directory server (LDAP) or email server. This prevents users from signing into the device or using centralized authentication services. It is commonly triggered by security policy changes in the network or expiration of the service account's credentials in the central server.

  • 2Expired LDAP server SSL/TLS certificates.
  • 3Time skew between the directory server and the printer.
  • 4Changes in LDAP server security levels.

Solutions

Quick Diagnosis

The error occurs when scanning or logging into the printer. If persistent, check if the LDAP server recently required a security update, such as a new SSL certificate.

Step-by-Step Solution

  1. Network Verification: Confirm the LDAP server is reachable from the printer's subnet.
  2. Credential Validation: Verify in the Xerox web interface that the service user account is currently active.
  3. SSL/TLS Setup: Ensure the Xerox unit trusts the LDAP server's root certificate.
  4. Reboot: Apply changes and restart network services on the printer.

Prevention and Maintenance

Keep device firmware updated to ensure compatibility with modern LDAP encryption standards. Use robust service accounts with no password expiration to prevent downtime.

When to Call a Technician

If the LDAP server is functional and credentials are verified valid, but the printer still displays 003-754, advanced routing settings or controller firmware may need specialist attention.
