Printhead reservoir
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.
