I'm not sure if I am posting to the correct board. I have an old Pixma MG7720 printer I am trying to recycle. I would like to delete any memory stored on it but when I google this question, the instructions point to start at a Settings/Registration button which I cannot find on this model. The only settings button I have is under the Setup tab and the Management Settings and Data Management tabs are the next steps after Settings/Registration are no where to be found. Of course it's out of warranty so I cannot get any help from Canon. Thanking anyone that can help me in advance.
