Abstract
The present invention provides a printing apparatus that can circulate ink stably regardless of the condition of the ink supply source, thereby effectively preventing ink sedimentation and separation within the supply channel. [Solution] The printing apparatus 100 includes a plurality of cartridges 12A, 12B, an ink ejection unit 40, supply valves 20A, 20B, a supply channel 30 piped to combine the ink Q supplied from each of the plurality of cartridges 12A, 12B via the supply valves 20A, 20B and supply it to the ink ejection unit 40, a circulation mechanism 50 that performs a circulation operation to return the ink Q supplied to the ink ejection unit 40 to the upstream of the supply channel 30, and a control unit 60 that controls the opening and closing of the supply valves 20A, 20B and the circulation operation of the circulation mechanism 50. The control unit 60 controls the supply valve corresponding to at least one of the plurality of cartridges 12A, 12B to be in an open state while the circulation operation of the circulation mechanism 50 is performed.
