摘要： In the particular embodiment of a device for removing dissolved gas from ink described in the specification, an elongated ink path leading to an ink jet head is formed between two permeable fluorine-containing membranes. The membranes are backed by air plenums which contain support members to hold the membranes in position. Reduced pressure is applied to the plenums to extract dissolved gas from the ink in the ink path without accumulating scum on the membrane surfaces. Increased pressure can also be applied to the plenums to eject ink from the ink jet head for purging. Within the ink jet head, ink is circulated convectively from the orifice to the deaerating path even when the jet is not jetting ink.

摘要： In the ink jet head described in the specification, a reservoir body contains three ink reservoirs and a vacuum reservoir and a cover plate at the front of the reservoir body provides passages to supply ink from the ink reservoirs to an ink jet array from which ink is selectively ejected in response to electrical signals. Air-permeable, ink-impermeable membranes in a lung plate adjacent to the cover plate provide one wall of the ink passages, and the opposite sides of the membranes communicate with the vacuum reservoir. The reservoir body is made of a heat-conductive material and is removably received in an insulating housing containing a cartridge heater which supplies heat to the bottom of the reservoir body.

摘要： An ink jet head has a reservoir containing hot melt ink and an orifice plate with orifices, along with passages leading from the reservoir to the orifices to conduct ink thereto. The ink jet head includes a heater to melt the ink in the reservoir, along with a further heater to heat air in the airspace above the ink in the reservoir, and the reservoir has a sealable vent which is sealed by a sealing element at a maintenance station so that heating of the air increases the pressure in the reservoir to cause purging, an absorbent member being provided at the maintenance station adjacent to the orifice plate to trap ink ejected during purging.
