20090122106 | Movable Fluid Receiver - A printer and method include a first receiver configured to receive fluid ejected by one or more print heads on a first side of a media and a second receiver configured to receive fluid ejected by the one or more print heads on a second side of the media, wherein the second receiver is movable relative to the first receiver. | 05-14-2009 |
20090167816 | INK JET METHOD FOR FORMING PATTERNED LAYER ON SUBSTRATE - An ink jet method for forming patterned layers on substrates permits a predetermined number of substrates to have respective patterned layers formed thereon. The inkjet method, however, further prevents clogging of the ink jet system when not in use to coat/layer substrates. A further step is provided, after all the desired substrates have been patterned, that making the liquid level of the ink in the nozzle changed within each predetermined time interval during/over the course of a predetermined amount of time. By changing the liquid level of the ink in the nozzle in a given period, each nozzle is able to remain unclogged (i.e., the ink in a nozzle does not have sufficient time to dry/harden prior to being jetted). | 07-02-2009 |
