摘要： An inkjet printer comprises an inkjet printhead and an ink reservoir contained in a pressurizable chamber, with an ink conduit interconnecting the ink reservoir and the printhead. An air compressor is in fluid communication with the chamber and a valve is positioned between the air compressor and the chamber. A first air conduit interconnects an outlet of the air compressor and the valve, while a second air conduit interconnects an inlet of the air compressor and the valve. The valve is switchable between a first configuration in which the valve interconnects the outlet and the chamber via the first air conduit, and a second configuration in which the valve interconnects the inlet and the chamber via the second air conduit.

摘要： A method of maintaining an ink ejection face of an inkjet printhead. The method comprises the steps of: (i) flooding the ink ejection face with ink from nozzles in the printhead; and (ii) rotating a roller adjacent the face, such that flooded ink is transferred from the face onto an outer surface of the roller. The outer surface of the roller does not contact the face during rotation of the roller.

摘要： An inkjet printer comprises a printhead having an ink ejection face and an ink supply system including a face flooding system. A sheet feed arrangement feeds a disposable sheet past the printhead and through a maintenance zone spaced apart from the face, and a print media feed arrangement feeds print media past the printhead and through a print zone. The maintenance zone is nearer the face than the print zone, and no part of the disposable sheet makes contact with the printhead.

摘要： An inkjet printer includes an inkjet printhead and an ink pressure regulator in fluid communication with the printhead via an ink line. The regulator includes an ink chamber having an ink outlet connected to the ink line; an air inlet; a regulator channel having a first end communicating with the air inlet and a second end defining a bubble outlet; and a wetting system for maintaining liquid in the regulator channel. The regulator channel is dimensioned to control a Laplace pressure of air bubbles drawn from the bubble outlet as result of supplying ink to the printhead, thereby regulating a hydrostatic pressure of the ink.

摘要： The invention relates to a maintenance station for an inkjet printhead assembly. The printhead assembly includes a carrier frame operatively supporting an ink supply manifold and a pagewidth printhead supplied with ink from said manifold. The station is moveable between a cleaning position and a printing position, and includes a drive motor, and a number of rollers of which at least one is operatively actuated by the drive motor. The station also includes a film wound in a loop around said rollers, so that actuation of the rollers by the motor produces a laminar ink flow in a cavity defined by the maintenance station and printhead assembly when in the cleaning position. This enables an ejection surface of the printhead to be cleaned without the film physically contacting said ejection surface.
摘要翻译：本发明涉及一种用于喷墨打印头组件的维护站。打印头组件包括可操作地支撑供墨歧管的载体框架和从所述歧管供应墨水的页宽打印头。车站可在清洁位置和打印位置之间移动，并且包括驱动马达，以及至少一个由驱动马达可操作地致动的多个滚轮。该站还包括围绕所述辊缠绕的膜，使得当处于清洁位置时，由马达产生的辊子由维护站和打印头组件限定的空腔中产生层流墨水流。这使得能够清洁打印头的喷射表面而不使膜物理接触所述喷射表面。

摘要： A inkjet printer that has an ink supply (112), a printhead integrated circuit (IC) (74) in fluid communication with the ink supply via an upstream ink line (67), the printhead IC (74), a waste ink outlet in fluid communication with the printhead IC (74) via a downstream ink line (106), an upstream shut off valve (138) in the upstream ink line (67), and, a downstream pump mechanism (114) in the downstream ink line. With a valve upstream of the printhead and a pump downstream of the printhead, the user has active control of the ink flow upstream, downstream or in the printhead IC. In the event that problems such as ink flooding, color mixing or printhead depriming occur, the user can follow simple troubleshooting protocols to rectify the situation.
