I have a Canon ImageClass FM8080cw that has started printing thick horizontal black bars on the first few prints of the day. After the first couple prints it works great until it sits overnight until the next workday. Ran all the cleaning/maintenance tasks on the printer and replaced the black toner (which indicated it was low) and the issue still persists. Wishful thinking that the back toner cartridge was just acting up.
Beside the toner there are no other user replaceable parts on this printer.
Any ideas what the issue could be? Thanks for any insight you might provide.
