Canon S9000 - purple band at end?
Had a similar problem with my S900. Seems that sometiimes the paper has a curl to it and will not feed properly at the end. Try taping an additional strip of paper to the end and see if there is an improvement. By curling my paper the problem stopped on my printer.
