    • An inkjet printer in which a printhead defines an elongate array of orifices from which jets of ink are projected into a space within which substrates to be printed are presented. An air curtain generator fixed in position relative to the printhead extends along one side only of the array of orifices so as to direct a curtain of air across the array a of orifices and across an open portion of the printhead on the side of the array of orifices remote from the air curtain generator. The air curtain cleans the printhead. A pressure pulse may be applied to ink within the printhead sufficient to discharge ink form each orifice when not in use to project ink. The pressure pulse has a relatively rapidly rising leading edge and a relatively slowly falling edge. An ink reservoir is coupled to the printhead for supplying ink to the orifices. The orifices may be arranged in at least two vertically offset groups, the reservoir being divided into vertically offset reservoir sections including a lowermost section and an upper section with each reservoir section being coupled exclusively to a respective group of orifices. The upper reservoir section is arranged to overflow into the immediately adjacent reservoir section which is spaced therebelow. Each reservoir section includes an ink level detector, and ink is supplied to the reservoir section which is vertically uppermost if any level detector detects an ink level below a predetermined level.
    • 一种喷墨打印机,其中打印头限定细长阵列的孔口,墨水射流从该孔口投射到待呈现基板的空间内。 相对于打印头固定就位的空气幕发生器仅沿着孔阵列的一侧延伸,以便引导空气幕穿过孔阵列a并穿过阵列侧面上的打印头的开放部分 远离气幕发生器的孔。 空气幕清洁打印头。 压力脉冲可施加到打印头内的墨水,足以在不使用时从每个孔口排出墨水以投射墨水。 压力脉冲具有相对快速的上升沿和相对缓慢的下降沿。 一个储墨器与打印头连接,用于向喷墨孔供墨。 所述孔口可以布置成至少两个垂直偏移的组,所述储存器被分成垂直偏移的储存器部分,所述储存器部分包括最下部分和上部部分,其中每个储存部分专门连接到相应的一组孔口。 上部储存器部分被设置成溢出到紧邻的储存器部分,该储存器部分在下面被间隔开。 每个贮存器部分包括墨水量检测器,并且如果任何水平检测器检测到低于预定水平的墨水水平,则墨水被供应到垂直最上面的贮存器部分。
