The pressure adjusting member is pivoted to the pressing plate for driving the pressing plate to move relative to the thermal print head, so as to press the plurality of resilient members for providing the thermal print head with pressure, such that the plurality of resilient members drives the pressing plate to equilibrate the pressing plate. | 07-11-2013 |
20130271548 | PRINTING APPARATUS - The invention provides a method of controlling the pressure applied to a substrate being printed by a thermal transfer printing head. The head displacement facility includes a resilient member such as a spring which undergoes deflection as the print head engages the substrate. The method comprises monitoring both print head position and spring deflection to control the pressure applied by the print head. | 10-17-2013 |
20130271549 | METHOD AND APPARATUS FOR THERMAL EXPANSION BASED PRINT HEAD ALIGNMENT - Automated print head alignment uses thermal expansion. By leveraging thermal expansion to position print heads within the carriage, the tedious manual adjustment process is eliminated. The need for costly precision references within the printer and on the print head is also reduced. | 10-17-2013 |
20130286136 | Print head assembly and printer using the same - A print head assembly and a printer using the same are disclosed. The print head assembly includes: a bracket, a print head and an elastic element. The bracket includes a first bracket body having a cavity and a lid covered on the opening of the cavity. A window is opened on the first bracket body. The print head is accommodated in the cavity of the first bracket body and hinged to the first bracket body via a first rotary shaft. The surface of a heating element of the print head is matched with the window and faces an outside paper pressing roller. The elastic element biases towards the print head so as to make the surface of the heating element of the print head have a tendency to extend outside the window. The print head assembly is capable of being detached as a whole, thus the requirements of performing single-sided printing and duplex printing in the same printer is achieved. | 10-31-2013 |
20140292989 | PRINTER APPARATUS AND PRINTING METHOD - A printer apparatus includes a printing medium supply unit that supplies a printing medium. An ink ribbon supply unit supplies an ink ribbon. A platen roller conveys the printing medium. A thermal head is arranged at a position opposite to the platen roller with the printing medium and the ink ribbon therebetween. The thermal head carries out printing by transferring the ink of the ink ribbon to the printing medium, A head pressing mechanism changes a distance or a pressure force between the thermal head and the platen roller. After the printing is ended, a control section controls the head pressing mechanism to raise the thermal head, the printing medium conveyance unit to convey the printing medium to a cutting position, and the head pressing mechanism to lower the thermal head immediately after the printing medium is cut. | 10-02-2014 |
20160082757 | DUAL MODE PRINTER - A thermal transfer flat bed printer that is configured for printing on flat objects includes a removable cylinder print module that is installed between a print head and the flat bed. The cylinder print module includes an alignment mechanism that engages with an alignment subsystem that moves with the print head and is separated from the print head by a predetermined distance. The engagement between the alignment mechanism and the alignment subsystem positions the module relative to the print head such that a cylindrical object supported by the module is in precise alignment with the print head, to within the tight tolerances associated with cylinder printing. The cylinder print module, which rests on but does not attach to the printer flat bed, includes rollers that are arranged to both support the cylindrical object and control the rotation of the cylindrical object, to maintain the cylindrical object in precise alignment with the print head during a cylinder print operation. | 03-24-2016 |
