Abstract: A print head priming system comprises a vent closure section to close a vent, where the vent is to compensate backpressure in a print head. An inlet to receive pressurized gas from a source of pressurized gas is to provide the pressurized gas to the print head. A pressure relief valve is to open in response to pressure in the print head reaching or exceeding a predetermined value by the provision of gas to the print head by the source of pressurized gas.

Abstract: A print head priming system comprises a vent closure section to close a vent, where the vent is to compensate backpressure in a print head. An inlet to receive pressurized gas from a source of pressurised gas is to provide the pressurized gas to the print head. A pressure relief valve is to open in response to pressure in the print head reaching or exceeding a predetermined value by the provision of gas to the print head by the source of pressurised gas.
