I have been trying to print from my laptop which my printer is connected with. However I am receiving some error messages, such as Canon Printer Error 6a80. What can be the reason behind the occurrence of such an error?
Canon Printer Error 6a80.
Is most likely a print head related hardware problem SO you need to go to the manufacturers own help site such as https://community.usa.canon.com/t5/Printer-Multifunction-Support/MX870-giving-error-msg-6A80/td-p/50929
Whatever model you own , this message is generally a physical print head issue and If you can not clear the fault yourself then you need an authorised repairer
