Hi; I have a MX300 Cannon printer which all of a sudden is giving me a "paper jam" error with no paper jam that I can see. Just before the error comes up there is a rotating sound within the machine as if it is looking for paper to put into position, but doesn't find it. There IS paper where it usually goes. DOes anyone have an idea what is happening? Thank you. I can say that just before this started the paper started to be inserted at a slight angle. Also once in a while I can do a printout but it sounds awfully wrong, noise wise. Thank you for your help. mrdibs.
