So i don't know what's wrong with my printer. It's an HP deskjet 3650. Until yesterday it was working fine, but then I turned it on and the power light keeps blinking the cartridge cart keeps moving one way to the other making really loud noises as if something was stuck but it has no paper stuck. I dont know what to do. I tried unplugging it but when I connect it back it starts soing the same things. There is no message error in Windows... Help needed !!!
