Where can you find the serial number on a Canon printer?

Most Canon printer models have serial numbers located on the interiors of the printers on either the front or rear top plates, as of 2015. However, there are some exceptions to this rule, including some multifunction Canon printers and models from the CP and ES lines.

Canon places the serial numbers of Canon CP or ES series printers on the bottoms of the printers rather than on their interiors. While some Canon multifunction printers have serial numbers located on the top plates of their interiors, other models have serial number located on the back or inside the printers' front panels.
