Solutions

Quick Diagnosis

Code 016-781 appears upon attempting to finalize the scan. It indicates the printer could not 'write' to the selected network destination.

Step-by-Step Solution

  1. Verify that the IP address of the destination server or computer is correct in the Xerox address book.
  2. Ensure that the credentials (username/password) configured for scanning have not expired.
  3. Check if the network folder still has active 'Write' permissions for the configured user.
  4. Try restarting the device and performing a test scan to a different IP address to rule out local network failures.

Prevention and Maintenance

Use a dedicated service account solely for printer scanning. Avoid frequent changes in domain security policies that may affect SMB connectivity.

When to Call a Technician

If the network is operational and permissions are correct, but the printer continues to reject the upload, the device might need an SMB protocol update (firmware).
