Abstract: A printing fluid cartridge (104) for a pumped printing fluid system containing a pump (110) is described, the printing fluid cartridge (104) comprising a housing (120) defining an interior chamber (122); a collapsible bag (124) within the chamber for holding a supply of printing fluid (126); and a fluid connection member (106) for forming a fluid connection between the collapsible bag (124) and an upstream side of the pump (110). The housing (120) includes a structure allowing the application of manual pressure to the collapsible bag (124) to urge printing fluid out of the collapsible bag through the fluid connection member (106) to the upstream side of the pump (110) to displace air (130) in the fluid connection member (106) and the pump (110).
