20100157004Multi-Color Ink Tank With Features Spaced by Distances Ensuring Interface with Printhead and Carrier Support Structure - A multi-color ink tank includes certain features that properly interface with features on a printhead and carrier support structure to operatively seat the ink tank in the carrier support structure in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the carrier support structure and thereby the reliable supply of ink for operation of the inkjet printing system.06-24-2010
20100165060Individual Ink Tank with Features Spaced by Distances Ensuring Interface with Printhead and Carrier Support Structure - A individual ink tank includes certain features that properly interface with features on a printhead and carrier support structure to operatively seat the ink tank in the carrier support structure in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the carrier support structure and thereby the reliable supply of ink for operation of the inkjet printing system.07-01-2010
20100165061Mono Ink Tank with Features Spaced by Distances Ensuring Interface with Printhead and Carrier Support Structure - A mono ink tank includes certain features that properly interface with features on a printhead and carrier support structure to operatively seat the ink tank in the carrier support structure in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the carrier support structure and thereby the reliable supply of ink for operation of the inkjet printing system.07-01-2010
20110012945FLUID HEIGHT BACKPRESSURE DEVICE IN A SYSTEM FOR SUPPLYING FLUID TO A PRINTHEAD - A fluid height backpressure system includes a printhead, a fluid supply tank, a backpressure device, and an air removal device. The backpressure device responsible for supplying system backpressure includes at least one tower disposed in an upright position and having a plurality of walls defining first and second chambers for respectively communicating with the ink supply tank and a fluid supply reservoir of the printhead. The air removal device provides additional back pressure in the second chamber, allows backpressure in the system to be maintained even with an empty fluid supply tank, and also supply of ink to the fluid supply reservoir of the printhead substantially without air bubbles being introduced therein. Also, ink sensors are utilized for sensing out-of-ink/ink-low conditions and also to help establish and continue the operation of the backpressure device.01-20-2011
20110012946FLUID HEIGHT BACKPRESSURE DEVICE IN A SYSTEM FOR SUPPLYING FLUID TO A PRINTHEAD - A fluid height backpressure system includes a printhead, a fluid supply tank, a backpressure device, and an air removal device. The backpressure device responsible for supplying system backpressure includes at least one tower disposed in an upright position and having a plurality of walls defining first and second chambers for respectively communicating with the ink supply tank and a fluid supply reservoir of the printhead. The air removal device provides additional backpressure in the second chamber, allows backpressure in the system to be maintained even with an empty fluid supply tank, and also supply of ink to the fluid supply reservoir of the printhead substantially without air bubbles being introduced therein. Also, ink sensors are utilized for sensing different levels of ink in the ink supply tank and out-of-ink/ink-low conditions in the backpressure device and also to help establish and continue the operation of the backpressure device.01-20-2011
20110012964FLUID HEIGHT BACKPRESSURE SYSTEM FOR SUPPLYING FLUID TO A PRINTHEAD AND BACKPRESSURE DEVICE USED THEREIN - A fluid height backpressure system includes a printhead, a fluid supply tank, a backpressure device, and an air removal device.
