I guess I assumed that by giving you a link to a page that says you have to call the parts department, you'd understand that you, well, have to speak with someone in the parts department. Sorry for the misunderstanding.
In case you couldn't find the information I referenced above, here it is:
Service Parts
Genuine Canon replacement service parts, including inkjet printer print heads, are available for purchase by calling the Canon Parts Order Desk at (866) 481-2569. If you require information regarding self-service repair, please call (877) 982-2666. Please note that for both product safety and optimal product operation, Canon recommends that most repairs be performed by a Canon authorized service technician.
