    摘要: Apparatus including a plurality of droplet ejection devices, an electric source and a controller (20). Each droplet ejection device (860) includes switches (Sc1, Sc2, … ScN) connected in parallel to a piezoelectric actuator (c). Each switch includes an input terminal to connect to an input waveform (Xv) signal, an output terminal to connect to the piezoelectric actuator, a control signal terminal to control a connection of the switch with a control signal, and a resistance (Rc1, Rc2, …RcN) between the input terminal and output terminal. The apparatus has a waveform table with information to distribute the input waveform signal to an input of each of the droplet ejection devices. The waveform signal table includes waveform signal information for a step pulse, a sawtooth waveform, and/or a combination of two or more waveform patterns.

    摘要: An ink jet printer includes an ink supply system and a printhead with nozzles for ejecting ink drops. The printer determines the average size of the ejected ink drops by comparing the number of ink drops ejected in a predetermined time with the quantity of ink delivered through the printers ink supply system during that time. If the determined average ink drop size does not match predetermined ink drop size criteria, the printer adjusts the activation signals for the ink jet nozzles to alter the ink drop size. A solid ink printer determines the quantity of ink delivered through the ink supply system by counting the number of whole or partial ink sticks that pass a predetermined point in the ink supply system. The counter detects a sensing element formed on an external surface of the ink stick. Exemplary detectors include a mechanical arm, or a thermistor to detect a change in the printer melt plate temperature due to a change in the cross sectional area of an ink stick being melted.

    摘要: A printing apparatus having a plurality of printing elements connected to a common power supply, each printing element (R1) is provided with a switching element (Q1) connected to the printing element in series for controlling driving of the printing element with a voltage applied to a control terminal; a constant voltage source (VR1) using the power supply as a standard, and a voltage control circuit (101) for controlling the terminal-to-terminal potential difference of the printing element to be equal to a voltage of the constant voltage source, when the printing element is driven, and when storage, driving signals to be supplied to each printing element are controlled so that energy amount consumed by each printing element is equal. Thereby a consumed energy amount in each printing element, that is, an energy amount generated at the time of driving becomes constant regardless of external conditions and environments of the printhead, resulting in high image quality storage.
