Abstract: A printhead reservoir has an input ink port (12) and a chamber (16) to receive ink from an ink source through the input ink port. The reservoir (16) also has a filter (14) 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 (28) 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. The reservoir has a filter (14) 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.

Abstract: PROBLEM TO BE SOLVED: To prevent ink suction into a jet part from being interrupted caused by a pressure decrease due to filter resistance, and to reduce cost for a filter.SOLUTION: A filter 14 prevents the clogging of a jet part or a nozzle 28 is arranged on a flow path or an ink injection path 22 from an ink injection port 12 through which ink supplied from an ink supply source passes to a chamber 16 for storing the ink by preventing particulates. The ink is stored in the chamber 16 between the filter 14 and the nozzle 28, so even if a pressure decrease before and after the filter 14 is generated, the nozzle 28 can normally suck ink. The filter 14 may be compact and inexpensive so that it can be mounted to the ink injection port 12. A vent path 26 is formed with a vent hole 18 in a top part of the chamber 16, so an internal pressure of the chamber 16 is automatically adjusted. It is preferable that a filter for preventing foreign matters is arranged in the vent hole 18.
