ipf 6300 squealling problem

I've been using the iPF6300 for about two years now, and I had a 6200 before that. I seldom, if ever, use Canon papers, and I've never heard my printers squeak or squeal, but then my hearing isn't as sharp as it used to be. I'll listen more closely next print job, but, in the meantime, I believe there is something wrong with your printer.
