Hi CSmith.
I will be able to assist you.
Please verify that printer is sitting on a level surface, and also check that the paper guides inside the cassette tray are flush against the paper. If this issue persists, we will have to recommend that you call us at 1-800-OK-CANON (1-800-652-2666), for further assistance.
I understand that the forum may be your preferred method of communication; however, the next steps must be performed with a telephone support representative assisting you.
