The Canon MP 470 is an all-in-one printer that can print, copy and scan. If you are attempting to replace the ink cartridge and repeatedly get a message on the LCD screen that says "Ink has run out," then you need to reset the printer by overriding the ink counter. Each Canon printer is equipped with a special ink chip that recognises when the ink has run low. However, if you are using generic or refilled cartridges, the printer might get confused.
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 recognise the cartridges before trying to print.
