A method of manufacturing a flexible circuit, including forming a first set of traces, forming a second set of traces, and cutting a gap between the first and second set of traces.

Method of manufacturing flexible circuit substracts

A print head has an ink reservoir to hold ink, the reservoir having protrusions, an external manifold coupled to the ink reservoir, the ink manifold having channels on a first surface that match the protrusions, and an adhesive in the channels to contact the protrusions. A method of assembling a print head includes mounting a jet stack to a flat plate of a merge fixture, dispensing adhesive on an external manifold attached to the jet stack, placing a reservoir in the merge fixture above the external manifold such that the reservoir does not contact the adhesive, attaching an upper plate to the reservoir to set a depth, pressing the reservoir into the adhesive, and curing the adhesive.

The disclosed print head has a two-chamber main reservoir that decouples wasted ink and purge volume in print heads. The two-chamber structure of the print head allows for varying flow of ink through the print head's internal manifolds without varying the wasted ink out of the jet stack. The main reservoir of the print head includes a recirculation chamber and an incoming ink chamber. A vacuum is applied to a vent in the recirculation chamber and a pressure can also be applied to a vent in the incoming ink chamber to cause bubbles in the jet stack to move into the recirculation chamber and be removed through the recirculation chamber vent.

A filter plate has an interior cavity, at least one filter contained in the interior cavity, a first port on a first side of the plate, at least one second port on a second side of the plate, forming a flow path with the first port through the filter, wherein the second port is positioned higher on the plate than the first port. A print head has an ink reservoir having an ink supply port connected to an ink supply, and a filter plate attached to the reservoir and positioned between the ink supply port and the ink reservoir, the filter plate including an interior cavity, at least one filter contained in the interior cavity, a first filter port on a first side of the filter plate in contact with the ink supply port, and at least one second filter port on a second side of the filter plate facing the ink reservoir, wherein the second port is positioned higher on the filter plate than the first port.

An ink collecting system has been developed to direct ink purged from a printhead positioned above an ink collecting tray along a stepped flow path into the ink collecting tray. The stepped flow path enables the purged ink to flow from a faceplate on the jet stack, around a junction, onto a lower surface of the jet stack, and to a curved lower flange of a reservoir housing, which directs the ink away from the faceplate before the ink drops into the ink collecting tray for disposal or reuse.

A flexible circuit substrate has an integrated circuit mounted on the substrate, a first set of traces arranged to connect between a first voltage source and a first set of connectors on the integrated circuit, a second set of traces arranged to connect between a second voltage source and a second set of connectors on the integrated circuit, and a gap in the flexible circuit substrate between the first and second set of traces, the gap of sufficient width to stop an electrical arc-tracking between the first set of traces and the second set of traces. The substrate may have a second gap between the first gap and other traces.

An insulation container has an insulation material, a filter arranged to encase the insulation material, the filter of a material that prevents escape of the insulation material while allowing air to pass through, and a container arranged to encase the filter, the container being heat sealable. A printer has an ink supply, a print head arranged to receive ink from the ink supply and configured to receive electrical signals from a controller and to dispense ink in accordance with the electrical signals onto a print substrate, and an insulator to absorb heat from the print head. A method of manufacturing an insulator includes forming a filter container of a filter material, the filter material having openings small enough to prevent escape of the filter material and large enough to allow air to pass through, filling, at least partially, the filter container with an insulating material, sealing the filter container, inserting the filter container into a sealable container, applying a vacuum to the sealable container such that the vacuum is applied to the filter container as well, and sealing the sealable container.

A volumetric container for storing phase-change ink includes a housing that is comprised primarily of a thermally insulating material and a heater element positioned within the housing. The heater element is positioned in the container to melt solid ink quickly to enable printing operations.
