Stuck in Open Inkjet Door mode and won't print

“My Canon MG 3500 series printer keeps giving me the message that the ink cartridge door is open and it won't print. I've tried opening and closing it many times, as well as turning on and off the printer. I even tried unplugging it and moving the ink cartridges around a bit. No luck! This is quite a new printer and I hate to put it into electronic waste already. Any suggestions out there?”
