Your printer uses black and tricolour ink cartridges with combined sponges and print heads. These Canon cartridges are all the same design for different model numbers, only the capacitances vary.
Like on the printer models with separate ink tanks and print head, ink level monitoring can also be disabled to allow printing with refilled cartridges.
Here is a druckerchannel.de article about refilling these cartridges, and here is a Google translation to English.
If the nozzles are clogged in these pcartridges, they might be unclogged. Here is a description for an HP cartridge, which is similar in design to your cartridges. Instead of dish washing liquid and water, you can also use a window cleaner with ammonia.
