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.

Printing fluid supply carrier

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.

Service routine based supply replacement determination

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.

Printer servicing

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

Structure for printhead having multiple air channels

A liquid permeable interconnect membrane for a liquid supply outlet, and a void between the interconnect membranes and an opposite void wall, the interconnect membrane being stiff enough to avoid unwanted pore deformation or contact with the opposite void wall.

Interconnect membrane

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.

Fluid cartridge

An ink supply container includes a first portion and a second portion. The first portion is configured to hold a first volume of ink and is configured to be releasably connectable to a printhead. The second portion is configured to hold a second volume of ink and is in communication with the first portion. The second portion is configured to extend over a top of at least one other ink supply container upon releasable connection of the first portion of the container to a printhead assembly.
