Inkjet recording device capable of performing ink refresh operation without stopping printing operation |
摘要 |
A sheet-position synchronizing signal is generated once each time a recording sheet is transported by a single-line worth of distance in a sheet feed direction. A print-driving signal and a refresh-driving signal are generated within a time interval of two successive sheet-position synchronizing signal. When the print-driving signal is applied to a piezoelectric element of a nozzle, then a print ink droplet is ejected, thereby a dot is formed on a recording sheet. On the other hand, when the refresh-driving signal is applied to the piezoelectric element, then a negatively-charged refreshing ink droplet is ejected. The refresh ink droplet refreshing ink droplet is deflected by an electric field and collected by a metal mesh without reaching the recording sheet.
