The cartridge is number 33 or 33 XL.
2025-11: moved it around an lost charger cable. Bought new cable www.amazon.co.uk/dp/B08YDJ9N6W "USB 2.0 Type A Male to B" but not turning on using chargers that work for cell phone, so I'm not sure if a charger problem, or if it printer was broken while deplacing it...
