Serial Number Format
Changes to Xerox products are made to accommodate improved components as they become
available. It is important when ordering parts to include the following information:
• Component's part number
• Product type or model number
• Serial number of the printer
The serial number is found on a label located on the rear frame of the printer just inside Door

The nine-digit serial number has the following format:
