Publication number: 20130229473Abstract: An apparatus includes an inkjet assembly having inkjet nozzles through each of which ink flows at a nominal flow rate as it is ejected from the nozzle onto a substrate. Ink is held under a nominal negative pressure associated with a characteristic of a meniscus of the ink in the nozzle when ejection of ink from the nozzle is not occurring. The apparatus includes recirculation flow paths, each flow path having a nozzle end at which it opens into one of the nozzles and another location spaced from the nozzle end that is to be subjected to a recirculation pressure lower than the nominal negative pressure so that ink is recirculated from the nozzle through the flow path at a recirculation flow rate.Type: ApplicationFiled: March 5, 2013Publication date: September 5, 2013Applicant: FUJIFILM DIMATIX, INC.Inventors: Robert L.

Patent number: 8491100Abstract: A piezoelectric ink jet head that includes a polymer film, for example a flex print, located between the piezoelectric element and the reservoirs in the jet body. The film provides an efficient seal for the reservoirs and also positions the electrodes on the side of the piezoelectric element in which motion is effected, which can reduce the magnitude of the drive voltage. This location of the compliant flex print material also can enhance electrical and mechanical isolation between reservoirs, which improves jetting accuracy. The compliance of the polymer also reduces strain on the ink jet head.Type: GrantFiled: December 2, 2008Date of Patent: July 23, 2013Assignee: FUJIFILM Dimatix, Inc.Inventors: Edward R. Moynihan, Paul A. Hoisington, Yong Zhou, Amy L. Brady, Robert G. Palifka

Publication number: 20130148167Abstract: An electronic architecture for an imaging data path allows for printing on objects that are unevenly spaced. The architecture uses a rolling image buffer into which images are copied. A hardware trigger can optionally be used in conjunction with the rolling image buffer to prevent any printing mismatches that could otherwise be caused by a software delay. The trigger relates the physical location of the object to a virtual location in the image buffer.Type: ApplicationFiled: February 7, 2013Publication date: June 13, 2013Applicant: FUJIFILM DIMATIX, INC.Inventor: FUJIFILM DIMATIX, INC.
