Abstract (en)
An ink jet apparatus utilises a bubble trap (20) in the supply line (22) from the reservoir (44) to the inlet (18) to the jet. The bubble trap (20) includes a screen (42) at the bottom of the bubble trap on the inlet side so as to block the flow of ink through the inlet (18) with an air bubble trapped at the screen (42). A valve (60) in the ink flow line (46) leading to the bubble trap (20) is spaced from a needle (48) which pierces the septum (50) of a cartridge (44). The valve (68) is located downstream from the needle (48) and septum (50).
