Patent number: 7748822Abstract: The ink jet printer comprises a printhead (22) movable in front of a printing medium (30) and provided with an ink cartridge (25) integral with it; the cartridge is filled with ink from a main, high capacity tank (35), which is connected at intervals to the cartridge (25) by means of a capillary element. During each connection, the capillary element (101) is brought into contact with the sponge (41) inside the cartridge, while a peristaltic pump (134) mounted integral upon the main tank provides a pressure suitable for generating a sufficient flow of ink to refill the cartridge (25) in a short time frame. To perform the refilling, the cartridge is brought at the end of its stroke into a service station (5) mounted on the body of the main tank (35), which is moved against the cartridge by means of a motor-driven linkage, controlled by a refilling management programme, in response to the signals of a cartridge ink level sensor.Type: GrantFiled: June 29, 2007Date of Patent: July 6, 2010Assignee: Telecom Italia S.p.A.Inventors: Alessandro Scardovi, Roberto Morandotti, Marco Brigando, Marco Dellea, Alberto Colombi, Gianrico Scarton

Patent number: 6565078Abstract: A device (10) for feeding sheets from a ream (22) comprising a main feeding roller (24) subdivided into a plurality of sleeves (32) which rotate in contact with an uppermost sheet (23a), coming from the ream, to feed it along a path (30), and an auxiliary separating roller (26) adapted for separating the uppermost sheet (23a) from the other sheets of the ream (22), wherein the feeding and separating rollers (24, 26) are both arranged on the same side with respect to said path (30) and therefore rotate in contact with one and the same side of the uppermost sheet (23a). The separating roller (26) is accommodated in a central seat (34) made between the sleeves (32) of the main feeding roller (24) and is arranged prevalently inside the radial working envelope of the sleeves (32) of the main feeding roller (24), so that the feeding device (10) has an extremely compact structure.Type: GrantFiled: October 12, 2001Date of Patent: May 20, 2003Assignee: Olivetti Tecnost S.p.A.Inventors: Roberto Foglino, Marco Dellea
