Abstract: A method for delivering a predetermined amount of fluid from a fluid ejection head. The method includes measuring one or more parameters selected from fluid flow parameters and electrical parameters for the fluid ejection head to provide one or more measured parameters; calculating a fluid ejection offset value from the one or more measured parameters; storing the fluid ejection offset value in a memory location on the fluid ejection head; accessing the fluid ejection offset value by an ejection head controller; and adjusting an amount of fluid ejected from the fluid ejection head during a fluid ejection step using the fluid ejection offset value to provide the predetermined amount of fluid from the fluid ejection head.

Abstract: A method of forming a print head, by forming a heater chip. Via zones having peripheries are defined on a substrate, with heaters formed along the entire peripheries of the via zones. Traces that electrically connect to each of the heaters are formed. In some embodiments, the heater chip is then stored for a period of time. After storing the heater chip, vias are formed in only a selected portion of the via zones, which is a subset of the via zones. A channel layer is formed on the heater chip by forming a first layer on the heater chip. Flow channels are formed in the first layer from the vias to only those heaters on the heater chip that are disposed along the selected portion of the via zones. Bubble chambers are formed in the first layer around only those heaters on the heater chip that are disposed along the selected portion of the via zones. A nozzle plate in formed on the channel layer by forming a second layer on the first layer, and forming nozzles in the second layer above only those heaters on the heater chip that are disposed along the selected portion of the via zones.

Abstract: A pipette-fillable fluid reservoir body. The fluid reservoir body includes two or more discrete fluid chambers therein. At least one of the fluid chambers contains a pressure compensation device and at least another one of the fluid chambers is devoid of a pressure compensation device. Each of the fluid chambers is in fluid flow communication with a fluid supply via, and each of the fluid chambers have sidewalls and a bottom wall attached to the side walls, wherein the bottom wall slopes toward the fluid supply via. The fluid reservoir body also includes an ejection head support face in fluid flow communication with the fluid chambers for attachment of a fluid ejection device to the ejection head support face for ejecting fluid from the fluid chambers.

Abstract: A portable large format inkjet printer for printing an image at a media print area of a stationary flat media includes an inkjet print engine having a printhead carrier system configured to dynamically scan an inkjet printhead over the media print area in each of two orthogonal directions during the printing of the image. An alignment frame is configured to fixedly mount the inkjet print engine to facilitate a manual positioning of the alignment frame and the inkjet print engine in unison. The alignment frame has an open interior window within which the inkjet printhead is moved and from which all printing occurs. At least one alignment panel is mounted to the alignment frame. Each respective alignment panel has an alignment indicia configured to facilitate accurate manual positioning of the portable large format inkjet printer at a desired printing position at the media print area.
