20090102906 | INK-JET PRINTER COMPRISING A STRUCTURE TO ELIMINATE INK DRIPPING - This invention provides an ink jet assembly that prevents and controls ink drips from upper print heads from contacting the lower print heads or paper in the system. A heated ink drip bib is provided below the ink jet releasing portion of a print head. This ink drip bib directs falling or dripping ink into a drip tray located below each ink bib during the purge cycle. The ink bibs and the drip trays are co-extensive so that any ink being deflected from the ink bib is caught by the ink tray. In one embodiment, the ink bib is angled away from the printing surface to ensure that any solidified ink is separated from an imaging surface. | 04-23-2009 |
20110141212 | SOLID INK MELTER ASSEMBLY - A solid phase change ink melter assembly in a phase change ink image producing machine comprises an array of a plurality of spaced apart fins, the array defining a top face for receiving the solid pieces of phase change ink, a bottom face for discharging melted ink, and opposite melter surfaces for melting the solid pieces in contact therewith. The assembly further comprises a number of heat transfer devices extending through and in heat transfer contact with the plurality of fins, the heat transfer devices including a heating element for heating the device. The bottom edge of the fins defines a plurality of apexes which serve as drip points for molten phase change ink. | 06-16-2011 |
20110273521 | High Flow Ink Delivery System - A system and method is provide for delivering molten ink to a printing mechanism including receiving molten ink in a receiving reservoir, and alternating which of a plurality of reservoirs is opened to the receiving reservoir to receive molten ink while at least one other of the plurality of reservoirs is opened to dispense molten ink to the printing mechanism, in response to the level of ink in a reservoir dispensing molten ink to the printing mechanism. | 11-10-2011 |
20110315031 | WEB PRINTING SYSTEMS HAVING SYSTEM RESONANCE TUNER - A method and apparatus herein supply one or more media characteristics of a continuous media material (such as printing media) being supplied to rollers of an apparatus (such as a printing apparatus). The method and apparatus adjust the position of at least one of the rollers/shafts, relative to other rollers/shafts, based on the media characteristics to cause the media material to exhibit a target resonance frequency when being processed through the rollers. The method and apparatus can also identify excitation frequencies of vibrations produced by the apparatus as the apparatus feeds the continuous media material along the rollers and set the target resonance frequency at a value that is different from the excitation frequencies to prevent the apparatus from exciting the continuous media material at or near a resonant frequency of the processing system transporting the continuous media material. | 12-29-2011 |
20120189370 | MEDIA PROTECTOR FOR IMAGE-FORMING DEVICE - A system for protecting media in an image-forming device. The system includes a heating element for heating the media, and a media path adjacent to the heating element. The media is transported in the image-forming device along the media path. The system also includes a barrier assembly having one or more non-flammable restraint threads and a spring-tensioned positioner. The restraint threads are mounted between the heating element and the media path, and the spring-tensioned positioner assembly maintains the restraint thread in a fixed position. | 07-26-2012 |
20120236093 | SOLID INK MELTER ASSEMBLY - A solid phase change ink melter assembly in a phase change ink image producing machine comprises an array of a plurality of spaced apart fins, the array defining a top face for receiving the solid pieces of phase change ink, a bottom face for discharging melted ink, and opposite melter surfaces for melting the solid pieces in contact therewith. The assembly further comprises a number of heat transfer devices extending through and in heat transfer contact with the plurality of fins, the heat transfer devices including a heating element for heating the device. The bottom edge of the fins defines a plurality of apexes which serve as drip points for molten phase change ink. | 09-20-2012 |
20120242764 | SOLID INK MELTER ASSEMBLY - A solid phase change ink melter assembly in a phase change ink image producing machine comprises an array of a plurality of spaced apart fins, the array defining a top face for receiving the solid pieces of phase change ink, a bottom face for discharging melted ink, and opposite melter surfaces for melting the solid pieces in contact therewith. The assembly further comprises a number of heat transfer devices extending through and in heat transfer contact with the plurality of fins, the heat transfer devices including a heating element for heating the device. The bottom edge of the fins defines a plurality of apexes which serve as drip points for molten phase change ink. | 09-27-2012 |
20120320134 | High Flow Ink Delivery System - A method for delivering molten ink to a printing mechanism alternates between a first and second reservoir receiving molten ink from a receiving ink reservoir while providing ink from the other of the first and second reservoirs to a printing mechanism. The alternation of the two reservoirs is achieved with coordinated operation of two actuators operatively connected to two seal members. | 12-20-2012 |
20140327723 | CONTAINER FOR DELIVERING SOLID-INK PELLETS - The present disclosure provides systems and methods for supplying solid-ink pellets from a container to an image-forming device. The system includes a delivery tube within the container, with one or more openings to receive solid-ink pellets from the container. An agitating structure coupled to the delivery tube disturbs the solid ink pellets. The movement of the delivery tube moves the agitating structure, resulting in disturbing the solid-ink pellets and maintaining flowability of the pellets to the image-forming device. | 11-06-2014 |
