Hello,
The lines look like there is something on the ITB or there is something wrong with magenta or cyan toner cartridge. You can reseat the color cartridges and check for any toner leaks. You can also check the inside of the printer for any loose toner powder that you can wipe up with a damp cloth. If that does not resolve the issue, you can try replacing the toner. If you continue to have issues, it looks like the printer needs service. You can check your available service options by logging into your MyCanon account or contact support over the phone at 1-800-652-2666. Our agents would be happy to help.
