I have recently bought the canon iP7260 printer to use as an edible printer.

I am having trouble with the set up of the edible ink cartridges as the lamps do not want to stay lit when inserting the colours. They click in fine. Four stayed lit and then when inserting the last colour they all went off. Next time I try one goes ok then when inserting the next they go off.

Frustrating!!

Can anyone suggest how I can rectify this?

Thanks
