Step 1
Make sure your Canon printer is turned on.
-
Step 2
Lift up on the front edge of the scanning unit. It will swing up and back. Make sure the scanning unit support, a plastic bar, swings down and into the obvious notch in the base of the unit. This will hold the scanning unit open while you work.
-
Step 3
Apply gentle downward pressure on the leading edge of the ink cartridge you intend to replace until you can slide it carefully toward you, out of the cartridge holder. Take care not to touch anything inside the printer--you may damage sensitive parts--and handle the spent cartridge carefully to keep from getting ink on yourself.
-
Step 4
Remove a new ink cartridge from its plastic packaging and gently pull the thin protruding slip of protective tape away from its terminals and nozzles. Make sure not to touch any terminals or nozzles protected by the tape.
-
Step 5
Slide the new ink cartridge into place. Black ink usually goes into the left-hand cartridge holder, and colored ink will typically go into the right-hand cartridge holder. Lift the leading edge of the cartridge gently until you hear it snap into place.
-
Step 6
Lift the scanning unit enough to remove the scanning unit support from its notch, then fold the support flat against the scanning unit again. Lower the scanning unit back into place.
