Xerox AltaLink C8170 047-749 Error: Solution

The Xerox AltaLink C8170 error 047-749 frequently occurs during scanning, specifically when the device cannot process the selected file format or when the resulting document size exceeds limits imposed by the SMTP mail server. This error can also trigger if the file generated is too complex for the device's image compression engine.

  • 2Incompatible file format selected for network settings.
  • 3Memory issues in the image processing engine for complex files.
  • 4SMTP server authentication failure during attachment transmission.

Solutions

Quick Diagnosis

If this error occurs consistently with large files, it is highly likely a size limitation imposed by the mail server or a conversion error for high-resolution PDFs.

Step-by-Step Solution

  1. Reduce quality: Lower scan resolution from 600 DPI to 300 DPI.
  2. Change format: Try sending as JPEG or simple PDF instead of searchable PDF.
  3. SMTP Verification: Check in CentreWare if the SMTP server has restrictive attachment size limits.
  4. Simple test: Scan a single page to rule out problems with overall document length.

Prevention and Maintenance

Configure the device to save auto-scans to a network folder instead of emailing them if the volume is high and the resolution needs to be maximum. This avoids the limitations of SMTP servers.

When to Call a Technician

If the 047-749 error persists even with simple single-page documents at minimum resolution, this may indicate a fault in the scanning control board or an internal image processing firmware error.
