20080218566 | Metallized print head container and method - Various embodiments of a metallized print head container and method are disclosed. | 09-11-2008 |
20080266370 | Compact Ink Delivery In An Ink Pen - In one embodiment an ink pen for an inkjet printer includes: an ink filter chamber; a pressure regulator chamber downstream from the ink filter chamber along a path of ink flow through the pen; a pressure regulator in the pressure regulator chamber; a filter in the ink filter chamber; an inlet to the ink filter chamber upstream from the filter along the ink flow path; and an outlet from the ink filter chamber to the pressure regulator chamber downstream from the filter along the ink flow path such that ink flowing from the inlet to the outlet passes through the filter. In another embodiment a method implemented in an ink delivery system for an inkjet ink pen includes: chambering ink in the pen; filtering the chambered ink; and then regulating the pressure of filtered ink. | 10-30-2008 |
20090091606 | Flow Control In An Ink Pen - In one embodiment a pressure regulator for an ink pen includes: a diaphragm between a lower pressure region and a higher pressure region, the diaphragm movable toward the lower pressure region in response to an increase in a pressure difference across the diaphragm; a valve operative between an open position in which ink may flow into the lower pressure region and a closed position in which ink may not flow into the lower pressure region; a first lever rotatable on a first fulcrum in response to movement of the diaphragm toward the lower pressure region; and a second lever connected to the valve, the second lever rotatable on a second fulcrum in response to rotation of the first lever to move the valve from the closed position to an open position. | 04-09-2009 |
20110120572 | FLUID SUPPLY - A fluid supply includes a container ( | 05-26-2011 |
20110197991 | FLUID SUPPLY CAP - A fluid supply includes a container, a bag within the container and a cap. The cap provides a fluid interface in communication with an interior of the bag and a pressurization interface in communication with an interior of the container adjacent an exterior of the bag. The pressurization interface has a channel that concentrically extends about the fluid interface. | 08-18-2011 |
20120008882 | FLUID HANDLING SYSTEM - A fluid handling system includes a valve assembly within a needle that is movable from a closed state to an open state against a bias while engaging and moving a valve stem of a fluid supply from a closed state to an open state. | 01-12-2012 |
20120162324 | COMBINATION INK STATUS AND KEY ARRANGEMENT FOR INK SUPPLY - A removable ink supply comprises an ink container including a coupler configured to removably engage a receiver of an ink supply station of an image forming apparatus. The coupler includes an end portion including an array of key holes with each key hole configured to removably receive a respective one key of an array of at least partially conductive keys of the receiver of the ink supply station. A conductive component of the coupler is positioned within the coupler and spaced apart from the end portion. The conductive component is in axial alignment with at least some of the respective key holes to be positioned for selective, removable contact with at least some of the respective keys of the receiver. An absence or a presence of removable contact between the conductive component and the key indicates an out-of-ink status of the image forming apparatus. | 06-28-2012 |
20130088552 | METALLIZED PRINT HEAD CONTAINER AND METHOD - An ink container for an inkjet print head includes a substantially rigid body of polymer material, the body including a base and a side wall integrally formed with the base at a perimeter of the base, the body containing ink in a low pressure chamber, and the polymer material having moderate to high air permeability. A flexible film is sealed over the low pressure chamber, inwardly flexible in response to a decrease in pressure and ink volume in the low pressure chamber, and outwardly flexible in response to an increase in pressure and ink volume in the low pressure chamber. A metal is coated on a perimeter of the polymer body and on an outer exposed surface of the flexible film, the metal to form a metal coating configured to decrease the air permeability of the polymer body, the metal coating being formed from at least copper. | 04-11-2013 |
