【摘要】In a thermal ink jet print head, individually-controlled heating elements are separated into groups of heating elements. Redundant control lines for the separate groups of heating elements increase the print head's reliability by reducing the likelihood that a print head will be completely disabled by an electrical fault on the control lines that in prior art devices extended to all of the heating elements.
