20090141071 | LIQUID DROPLET JETTING APPARATUS - A printer comprises a fixed line type first head, a serial type second head, an ink cartridge which stores an ink to be supplied to the first and second heads, a first cap which is to be installed to the first head, and a second cap which is to be installed to the second head. The ink cartridge and the first and second heads are connected in series in this order by using tubes. Accordingly, it is possible to shorten the lengths of the tubes. The serial type head, in which the drying is hardly caused from a nozzle and the influence is exerted to a small extent on the jetting performance when any viscosity-increased liquid and/or bubbles is/are supplied, is arranged on the downstream side. Accordingly, it is possible to decrease the frequency of the recovery operation. | 06-04-2009 |
20090141074 | LIQUID DROPLET JETTING APPARATUS - A printer comprises a first head which has first nozzles, a second head which has second nozzles each having a nozzle diameter larger than that of the first nozzle, and an ink cartridge which stores an ink to be supplied to the first and second heads. The first head is directly connected to the ink cartridge by means of a tube. The second head is connected to the first head by means of a tube, and thus the second head is connected to the ink cartridge via the first head. Accordingly, it is possible to shorten the tubes by connecting the ink cartridge and the two heads in series. Further, it is possible to decrease the frequency of the recovery operation by arranging, on the downstream side in the liquid supply direction, the head in which the jetting failure is hardly caused. | 06-04-2009 |
20090141094 | LIQUID DROPLET JETTING APPARATUS - A printer includes a first head in which first nozzles are formed, a second head in which second nozzles located at a higher position than the first nozzle are formed, and an ink cartridge positioned at a lower position than the first and second nozzles. Moreover, the first head is connected to the ink cartridge via a tube, and the second head is connected to the first head via a tube. Accordingly, the second head is connected to the ink cartridge via the first head. It is possible to shorten the tubes by connecting serially the ink cartridge and the two heads, and to prevent from breaking simultaneously a meniscus in the nozzles of both the heads located at different height positions. | 06-04-2009 |
