Serial Number Location for CP/ES Printers

The printer's serial number is located on the bottom of the printer. It is typically a set of 10 digits with no letters or special characters. 

For example: 8501234567 or 1121234567

If there is a bar code on the bottom of the printer, then the serial number is displayed below it.
For models without a bar code, the serial number will usually follow the abbreviation for number ("No.").
