Canon PIXMA MP640 Paper Jam Error

"Error: Paper output slot. The paper is jammed. Clear the paper and press OK." Message won't clear even though all paper was cleared. Shut off for a couple of days. Finally got the Canon intro message on the LCD instead of error message. Thought making a copy (instead of printing) might "reset" the error. Error message on LCD again and won't clear. The manual does not have a graphic showing where paper sensor is located so I can check to see if "stuck". Any ideas where I the sensor is located? Any other ideas re error message? Thanks.
