20080211837 | Ink-Jet Recording Apparatus and Recording Method Therefor - A recording apparatus has a recording head, a platen, and a first hole. The recording head includes a dot formation element array, and the platen holds a recording medium opposite the recording head. The first hole is disposed in an area of the platen opposite a downstream portion of the dot formation element array and guides ink discarded outside an end of the recording medium when the end is printed without a margin. Alternatively or additionally, a second hole is formed in an area of the platen opposite an upstream portion of the dot formation element array, and the platen guides ink, which is discarded outside an end of the recording medium when the end is printed without a margin, to the second hole. | 09-04-2008 |

20120200649 | LIQUID CIRCULATION SYSTEM AND INK-JET PRINTER - An ink circulation system includes: an ink-jet head in which a shared ink flowing route is formed, an ink tank, a supply flowing route for supplying ink from the ink tank to the shared ink flowing route, a reflux flowing rout for refluxing the ink from the shared ink flowing route to the ink tank, and a differential pressure generating unit for generating a differential pressure in the ink tank. The differential pressure generating unit is equipped with an impeller placed inside the ink tank, and a drive unit placed outside the ink tank. Then, the drive unit operates to turn the impeller, by means of remote driving, for generating a differential pressure between a supply port of the supply flowing route and a reflux port of the reflux flowing route so as to circulate the ink through the ink flowing route. | 08-09-2012 |
20130010037 | LIQUID CIRCULATION SYSTEM - A liquid circulation system includes an inkjet head formed with a common ink flow passage, an ink cartridge, a supply flow passage through which ink is supplied from the ink cartridge to an inlet of the common ink flow passage, a return flow passage through which the ink is returned from the outlet of the common ink flow passage to the ink cartridge, a tube pump sending the ink in the supply flow passage, a tube pump sending the ink in the return flow passage, a pressurization bellows unit pressurizing the ink in the supply flow passage, a pressure reduction bellows unit depressurizing the ink in the return flow passage, a pressurization regulator maintaining the inlet being a center value “+α” of a designated head value, and a differential pressure regulator by which a differential pressure of the ink between the inlet and the outlet is maintained to be “2α”. | 01-10-2013 |
