    摘要： An inkjet printer comprising: a printhead with a plurality of printhead IC's, each having an array of nozzles for ejecting drops of printing fluid, and drive circuitry for driving the array of nozzles; a print engine controller for sending print data to the printhead IC's; an interface for electrical communication between the print engine controller and the printhead IC's; wherein, all the printhead IC's have a common initial address except one printhead IC at the end of the printhead, the exception having a different address such that the print engine controller sends a first broadcast instruction to any printhead IC's having the different address, the first broadcast instruction instructing the printhead IC having the different address to change its address to a first unique address, the printhead IC's being interconnected such that when the exception has undated its address, the address of the adjacent printhead IC changes to the different address so that a second broadcast command changes the write address to a second unique address and so on until all the printhead IC's have unique addresses provided by the PEC.

    摘要翻译： 一种喷墨打印机，包括：具有多个打印头IC的打印头，每个打印头IC具有用于喷射打印流体液滴的喷嘴阵列，以及用于驱动喷嘴阵列的驱动电路; 用于将打印数据发送到打印头IC的打印引擎控制器; 用于打印引擎控制器和打印头IC之间的电气通信的接口; 其中，除打印头末端的一个打印头IC之外，所有的打印头IC具有共同的初始地址，异常具有不同的地址，使得打印引擎控制器向具有不同地址的任何打印头IC发送第一广播指令，第一 指示具有不同地址的打印头IC的广播指令将其地址改变为第一唯一地址，打印头IC被互连，使得当异常已经将其地址未注明时，相邻打印头IC的地址变为不同的地址，使得 第二广播命令将写入地址改变为第二唯一地址，等等，直到所有打印头IC具有由PEC提供的唯一地址。
