In this approach, the printing time can be minimized to a few milliseconds, because of the quick response time of the actuator. The thickness of the semi-solid state printer can be as low as few millimeters! The length and width can be customized as per the size of paper. In brief, it can be proved as extremely thin, incredibly fast and silent printer. | Journal of Automation and Control Engineering, Vol. 1, No. 1, March 2013 Semi-Solid State Printer Manoj Kumar Sharma SRM Varsity, Chennai, India imanoj_sharma@ Abstract—Printer is one of the important output devices, which is used widely. The existing ones are bulky and relatively slow thus requires more printing time (ppm), which is due to the moving mechanical parts and mechanical constrains. In this new idea, the array of piezoelectric actuators, in the form of layer is used to provide impact on a paper containing carbonic paper in between. This impact results in the deposition of loosely bound ink, of carbon paper, to deposit on the blank sheet. In this approach, the printing time can be minimized to a few milliseconds, because of the quick response time of the actuator. The thickness of the semi-solid state printer can be as low as few millimeters! The length and width can be customized as per the size of paper. In brief, it can be proved as extremely thin, incredibly fast and silent printer. Index Terms— actuator, array, crystal, carbonic paper, piezoelectric. I. INTRODUCTION The key element of this machine (printer) is the piezoelectric crystal, which acts as actuator. Actuator is the one, which converts one form of energy to another. The name “Semi-Solid State” speaks that the machine does not contain any moving part as incase of traditional printers, but still shows very small uniaxial displacement, for the process of printing. II. PIEZOELECTRIC CRYSTAL These crystals are kind of transducers, which basically converts electrical energy into mechanical stress and vice versa. Figure 1. B. Types Focusing on this application, there are two kinds of piezoelectric transducers available: 1) Direct piezoelectric actuator. These actuators are meant for relatively less stroke and a layer thinner than 100 micrometer can be constructed. The advantage in this type is that, it can be operated below 150 Volts, which is very much less than the .
