Twin dos cartridge not recognised

[Paul2101]

I can’t engage twin dos as each time I try I get the message replace cartridge 2. However that cartridge is full. Have tried reinserting several times, turned machine off and on , all with no luck. Tried to run maintenance programme but get same problem when told to insert cartridge into compartment 2 - it doesn’t recognise that the cartridge is inserted.

any ideas gratefully received.

Sorry, never seen one of those. Have you tried different cartridges in case it's a faulty cartridge?
