Turn off the Canon MP 470 and unplug it from the outlet.
Press the 'On/Off' button while you plug the cable back in.
Hit the 'Stop/Reset' button two times while holding down the 'On/Off' button, then let go of the 'On/Off' button. This puts the printer into factory mode.
Hit the right arrow button until you see 'Shipping Mode 3' on the LCD display. Hit 'OK' to select it.
Hit the 'Stop/Reset' button when you see a message that says 'Without Cleaning.' This tells the Canon printer to print out a test page.
Lift up the Canon MP 470 printer cover and wait for the cartridges to move to the left. Then unplug the printer from the outlet.
Lift out both ink cartridges and close the cover.
Plug the power cable back in and hit the 'On/Off' button.
Place the ink cartridges back inside once you see a message that says 'Replace Cartridges.' Wait a few minutes for the printer to recognize the cartridges before trying to print.
