Before getting deep into the troubleshooting solutions you must understand what this error is all about and why it occurs. The Canon printer uses the number of pages to print to calculate if the ink cartridges need to be refilled or not. However, the Canon Printer Error E13 occurs when the Canon printer is unable to recognize the ink cartridges that have been installed.
So, you will see the error E13 on the display of the printer when the ink cartridge runs out. So, this means that the E13 error occurs when there is something wrong in the ink cartridge.
