Title:
HEATING DISCHARGE PRINT HEAD DRIVE METHOD
Document Type and Number:
WIPO Patent Application WO/2007/102219
Kind Code:
A1
Abstract:
A heating discharge print head drive method for efficiently causing electric
discharge by controlling the timing at which a voltage is applied to a discharge
electrode and the timing at which the discharge electrode is heated. The energy
is excellently saved, the amount of ions produced is accurately controlled to
simply perform gradation recording, and a high-quality image can be created.
The method comprises a potential difference setting step of setting a potential
difference corresponding to the discharge control voltage between a heating
discharge print head having a discharge electrode and heating means for selectively
heating the discharge electrode and an opposing electrode opposed to the discharge
electrode in such a way that a recording medium writable/erasable by the action
of electric charge is interposed between the print head and the opposing electrode
so as to produce an electric field and a discharge electrode heating step of allowing
the heating means to selectively heating the discharge electrode according
to image information. At the head voltage applying step of the potential difference
setting step, the timing at which a drive voltage is applied to the discharge electrode
is synchronized with the timing of the discharge electrode heating step.
