My Canon Pixma MP530 prints just fine, but it makes a horrendous noise every time it boots up, and at other times such as preceding a print job. It sounds like a machine gun - a very loud rat-a-tat clicking noise. I'm at a loss as to what is causing this.![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
