A printhead reservoir has an input ink port and a chamber to receive ink from an ink source through the input ink port. The reservoir also has a filter in a path between the input ink port and the chamber. A printhead includes a reservoir having an input ink port, a chamber to receive ink from an ink source through the input port and a filter in a path between the input port and the storage plate. The printhead also includes an array of jets to draw ink from the chamber and control circuitry to control the jets so as to selectively output ink through the jets onto a substrate. A reservoir has a filter to receive ink, a vented chamber to collect ink received from the filter and at least one jet to receive ink from the vented chamber. The vented chamber is between the ink filter and the fluid path to the jets in order to remove the filter portion of the pressure drop to the jets.

A reservoir assembly for use in an imaging device, the reservoir assembly includes an ink input port configured to receive liquid ink from an ink source and an ink tank configured to receive ink from the input port. A filter is positioned between the input port and the ink tank configured to filter ink received via the input port prior to reaching the ink tank. The reservoir assembly includes a foam reducing path configured to guide ink that passes through the filter to the ink tank, the foam reducing path having a varying cross-sectional size and/or shape configured to collapse, compress, stretch, and/or shear air bubbles in foam that passes through the filter prior to reaching the ink tank.

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 system and process enable a device to adjust the duration of various power modes based on usage of the device. The process includes operating a device at a fully operational power level, counting a first wait time, modifying a first wait time modifier in response to detection of image generating device use prior to expiration of the first wait time, and reducing power consumption from the fully operational level to a low power level in response to expiration of the first wait time.

A method for operating a printer having multiple printheads includes activating a heater that is operatively connected to a printhead that ejects ink having a single color in response to receiving a print job. The printer detects the presence of colors other than the single color in image data received in the print job, and activates heaters operatively coupled to printheads that eject ink drops that correspond to the detected colors.

An apparatus has a first plate having a first array of holes, with a first plate alignment hole having a smaller size than the other holes in the array, a second plate having a second array of holes to be alignable to the first array of holes, a second plate alignment hole having a smaller size than the other holes in the array, and the first plate alignment hole and the second plate alignment hole having different positions. A method of aligning plates provides a first plate having a top and bottom and first array of holes including a first plate alignment hole having a size smaller than the other holes in the first array, places a second plate having a second array of holes on the top of the first plate such that the first array of holes and the second array of holes align, directs light at the bottom of the first plate, locates a profile of the first plate alignment hole in the second array of holes to verify alignment.

A solid ink stick melting apparatus is incorporated in a phase change printer to provide melted ink under pressure to a print head. The solid ink stick melting apparatus includes an ink stick melt chamber having an enclosure with at least one heated wall, an inlet for receiving an ink stick, and an outlet for melted ink flow from the enclosure, and a seal mounted proximate the inlet to engage an ink stick passing through the seal so that the seal and the ink stick form a barrier and retain melted ink within the enclosure.

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 reservoir is provided for a printhead in an ink jet printing machine, the printhead having at least one printhead inlet at a rear face thereof for flow of ink from the reservoir into the printhead. The reservoir comprises a perimeter wall sealably mounted to the rear face of the printhead and defining a chamber in communication with the printhead inlet. The chamber is open at one face and the reservoir includes a resilient flexible membrane attached to the perimeter wall and covering the one face. An inlet is provided in communication with the chamber for passage of ink into the chamber. The resilient flexible membrane has an initial relaxed condition in a first state in which the reservoir is substantially full of ink, and a flexed condition in which the membrane is collapsed into the chamber.
