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

Serial numbering. Particular fields in the serial number indicate the modification level of the printer, the date of its manufacture and the sequence number of the printer produced on that day.

The serial number is coded as follows:

  • The text "S/N" followed by the serial number in the barcode.
  • The barcode does not include a field identifier.
  • The nine digit serial number is based on the following format:

PPPRSSSSS

PPP = Three digit alphanumeric product code

Product Model Voltage Product Code
7750 B, DN, GX, DXF 110V RRW
7750V B, DN, GX, DXF 220V RTG

 

R - Single digit numeric revision digit. To be rolled when a major product change occurs. Initiated with a change request.

SSSSS - Five digit numeric serial number.

Serial Number Example:

RRW453072: RRW = Product code for the 110V Printer 4 = Revision level 53072 = Serial number

Using the Parts List

  1. No.: The callout number from the exploded part diagram.
  2. Part Number: The material part number used to order specific parts.
  3. Qty: This number represents the parts per printer, not the number of parts supplied in the actual part order.
  4. Name/Description: Details the name of the part to be ordered and the number of parts supplied per order.
  5. Parts identified throughout this manual are referenced PL#.#.#; For example, PL3.1.10 means the part is item 10 of Parts List 3.1.
  6. A black triangle preceding a number followed by a parenthetical statement in an illustrated parts list means the item is a parent assembly, made up of the individual parts called out in parentheses.
  7. The notation "with X~Y" following a part name indicates an assembly that is made up of components X through Y. For example, "1 (with 2~4)" means part 1 consists of part 2, part 3, and part 4.
  8. An asterisk (*) following a part name indicates the page contains a note about this part.
  9. The notation (NS) next to a part indicates that particular part is not spared, but contained in a kit or major assembly.
  10. The notation "1<>J2 and P2" is attached to a wire harness. It indicates that connector Jack 1 is attached to one end of the wire harness and connector J2 is attached to the other end that is plugged into P2.

Note

Only parts showing part numbers are available for support. Parts not showing part numbers are available on the parent assembly.
