Abstract: A replaceable printing fluid supply carrier for a continuous ink supply system of a printer is described in some examples. The printing fluid supply carrier comprises a printing fluid container carrier and a cover part connected to the printing fluid container carrier. When the printing fluid supply carrier is installed to the printer with a supply door opening an opening to a printing fluid supply area the cover part covers the opening to the printing fluid supply area.

Abstract: Examples include printing devices configured for use with a plurality of replaceable supplies. A remaining amount of printing material may be monitored for each replaceable supply. A set of one or more replaceable supplies to be replaced may be determined based at least in part on the remaining amount of printing material for each replaceable supply and an amount of printing material corresponding to performing a service routine for supply replacement.

Abstract: In one example of the disclosure, environmental data indicative of an environmental factor measured at a printer is received via a network. The receipt of the environmental data is via an authorized non-anonymous data flow from the printer. Instructions for a service event to occur at the printer are determined based upon the environmental data. The service event instructions are sent, via the network, to the printer to cause the printer to perform the service event.

Abstract: A structure comprises inlets through which respective liquids are to be introduced and multiple unique vent paths each corresponding to one of the inlets.

Abstract: The invention relates to an ink cartridge comprising a liquid ink, an extraction system for the liquid ink and a container for the liquid ink, the container having a non zero water vapor transmission rate, the liquid ink occupying a first region 411 of the container, the ink cartridge further comprising a second liquid, the second liquid occupying a second region 421 of the container, whereby the first and the second region are separated, and whereby the extraction system is in communication with the first region but is not in communication with the second region.

Abstract: A fluid container ship cap seals a plurality of fluid interconnects of a fluid container during one or both of shipping and storage. The fluid container ship cap includes an elastomeric seal having a plurality of fluidic sealing members to seal a corresponding plurality of fluid interconnects. The fluid container ship cap further includes a rigid shell to rotate the fluid container ship cap about an axis of rotation at a fulcrum provided by a first fluidic sealing member of the plurality of fluidic sealing members. The elastomeric seal is affixed to the rigid shell.

Abstract: A printer credit management method is disclosed, the method includes receiving a code at a printer. From the code, a printer identifier and a credit value are discerned. It is determined if the printer identifier corresponds to a unique identifier assigned to the printer. Only upon a positive determination, a credit balance maintained by the printer is updated to include the credit value.

Abstract: A fluid cartridge sub-assembly comprising a first vent bore, an elongate air channel, a cover extending over the first vent bore and the air channel, and a second vent bore connected to the air channel.

Abstract: In one example, a fluid cartridge for an inkjet type liquid dispensing device includes a housing having a chamber therein for holding a liquid, a vent through which air may enter the chamber, and an outlet through which liquid may pass from the chamber out of the housing. A capillary material is disposed in the chamber between the vent and the outlet so that, when the capillary material is sufficiently depleted of liquid, the capillary material forms an airway from the vent to the outlet. The outlet configured to cause an abrupt break in a liquid connection in the outlet as air enters the outlet through the capillary material.
