There is disclosed a fluid containeruseable with print apparatus. The fluid container comprises a primary modulecomprising: a primary reservoirto contain print fluid and a regulated chamberto receive the print fluid from the primary reservoir. The regulated chambercomprises a regulator unitto actuate a gas control valveto control a flow of relief gas into the fluid containeras print fluid is discharged from the fluid container. The fluid container comprises a secondary modulecomprising a secondary reservoirto contain print fluid. The primary reservoiris to receive the print fluid from the secondary reservoirvia a re-supply conduitbetween the secondary reservoirand the primary reservoir. The secondary reservoiris to receive the relief gas via the gas control valve, and the primary reservoiris to receive the relief gas via the secondary reservoir

Fluid containers

A printing material supply may include a body to contain a printing material, a latch pivotably coupled to the body by a living hinge and a latch protector. The latch protector may include a structure coupled to and projecting from the body so as to contact a packaging surface of a package to inhibit creep of the latch about the living hinge when the printing material supply is contained within the packaging.

Latch protector

Liquid supply or reservoir therefore having multiple compartments, each compartment to hold a distinct liquid, comprising multiple liquid outlets, each fluidically connected to one of the compartments, multiple clearance cut outs disposed at a pitch equal to a pitch of the compartments to accommodate protrusions of a dispenser, and at least one latch protruding outwards from a supply wall.

Replaceable liquid supply having cut outs and latch

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

In one example, a structure for supporting a printhead includes: a substrate having a first side and a second side; an inlet tower through which liquid may be introduced into the structure; an opening through the substrate near the inlet tower; and an air channel along the substrate connecting the opening in the substrate to the atmosphere.

Vent through a printhead support structure

In one example, a structure for supporting a printhead includes: a substrate having a first side and a second side; multiple inlets each protruding from the first side of the substrate through which liquids may be introduced into the structure from the outlets of liquid containers that can be attached to the structure; multiple openings through the substrate from the first side to the second side, each opening positioned near one of the inlets at a location exposed to the outlet of a corresponding one of the containers when the container is attached to the structure; and an air channel on the second side of the substrate connecting each of one or more of the openings to another opening.

Vent path for a liquid container

A method of manufacturing an electronic component comprising at least one n- or p-doped portion, comprising the steps of: co-depositing inorganic semi-conducting nanoparticles and dopant on a substrate, the nanoparticles being a group four element such as silicon or germanium; fusing the nanoparticles by heating to form a continuous layer; and subsequently; and, recrystallising the layer.
