A recording method in which ink is ejected by thermal energy produced by a heat generating element of a recording head in response to application of a driving signal thereto including the steps of changing a waveform of the driving signal in accordance with a temperature of the recording head; and selecting a fixed waveform of the drive signal when the temperature of the recording head exceeds a predetermined level.
摘要:
A recording method ejects ink by thermal energy produced by a heat generating element of a recording head in response to a drive signal. The method includes the step of controlling an amount of ejection of the ink by a temperature control for the recording head including at least heating of the recording head, when a temperature of the recording head is not higher than a predetermined first temperature. The method further includes the steps of controlling the amount of ejection of the ink by changing a waveform of the drive signal for ejecting ink in accordance with the temperature of the recording head when the temperature of the recording head is higher than the first temperature and not higher than a second temperature, and fixing the waveform of the drive signal when the temperature of the recording head is higher than the second temperature.

摘要:
An ink jet recording apparatus is disclosed in which a bubble is created in ink by thermal energy generated in response to a drive signal applied to a heater, and the ink is ejected onto a recording material by expansion of the bubble. The recording apparatus includes a driving device and a changing device. The driving device applies a plurality of driving signals to the heater for each ink droplet ejection. The driving signals include a first driving signal for increasing a temperature of the ink adjacent the heater without creating the bubble, and a second driving signal after the first drive signal for ejecting the ink. An interval is provided between the first and second drive signals. The changing device changes a width of the first drive signal to adjust an amount of ejected ink. The interval is not shorter than 2.6 microseconds and the second drive signal has a constant width.
摘要:
In the recording method and apparatus, ink is ejected by thermal energy produced by a heat generating element of a recording head in response to application of driving signals thereto, the driving signals being of plural waveforms including a fixed waveform. The method includes the steps of detecting a temperature of the recording head and applying the driving signals to the heat generating element of the recording head. The waveforms of the driving signals are changed in accordance with the temperature of the recording head when the temperature of the recording head is below a predetermined level, and the waveforms of the driving signals comprise the fixed waveform when the temperature of the recording head exceeds the predetermined level.
摘要:
An ink jet recording apparatus includes ink ejecting outlets for ejecting ink, an ink container for containing the ink to be supplied to the ejecting outlets, ink supply passage for supplying the ink from the container to the ejecting outlets, a recovery system for forcedly ejecting the ink through the ejecting outlets. The recovery system repeats the forced ejecting action, and a quantity of the ink ejected by one forced ejecting action is larger than an inside volume of the ink supply passage.
