Document Type and Number:
Japanese Patent JP2004518555
Kind Code:
A
Abstract:
The present disclosure relates to an inkjet printing system that includes an inkjet printhead having a plurality of electrical contacts: address contacts and enable contacts for enabling drop generators (42) and drive current contacts for providing drive current to enable drop generators for selectively ejecting ink therefrom. The printing device provides periodic address signals (A(1-13)) and enable signals (E(1-2)) to the address and enable contacts on the printhead. In addition, the printing device selectively applies drive current (P(1-16)) to accomplish forming images on print media. Each individual heating element (44) is controlled by a drive circuit comprising three FET (48, 50, 52). By controlling the first and second signals E(1) and E(2), and the address signal (A(1)) the switching device (48) is selectively activated to conduct current through the heating element (44) if drive current is present from drive source (P(1)).
