Hello, I have a Canon MG5270 and had a pretty bad paper jam the other day. Now every time I print something, anything that has bold print is smudged and there is a half-circle of black ink at the edge of the page. I have run every cleaning function at least twice and taken some q-tips to most of the internal parts that I can see and reach that look like they might have ink on them. I have attached a picture to illustrate what I am talking about. Any advice on what area I need to clean/replace to get rid of this?
