How do i put in ink carttriges for a canon ip1700 please help?

I've had the same problem with the Canon MP160. The book fails to mention that the cartridges go into a carriage which is usually on the right side of the machine. To get the carriage over to the left side, first turn on the power, then open the machine top, and the carriage will move over to the left side. Now you can install the cartridges as per the instructions and pictures.
