If you want to open your printer for cleaning print heads then use following instructions otherwise check [https://guideusermanual.com/product-name-ip3600-manual&po=216892&lang=English|Canon Ip3600 Manual]. * Open the cover and wait until the carriage aligns itself to the "stop mode" * Remove the cartridges and then lift the lever to the side of the carriage. * The print head is all black and comes out by lifting the side. * There are five ports where the ink enters from the cartridges. On the bottom you will see a white plate where the nozzles are situated.One long and one square. * Do not separate any parts of the print head. This is critical. Do not remove the two screws that secures the white base. This base is where the nozzles are situated. Leave all parts intact. * The ink can become like sludge or can dry inside the print head. * This is my solution to clean the print head: * Run hot water over the entire set of ports. You will see the colours run. Let the hot water run over these ports for a few minutes * Turn the head over and run the hot water over the nozzles. You will see colours coming out from the nozzels.
