Embodiment Construction

[0046] figure 1 The arrangement of nozzles in a 4-color printhead segment 92 is shown. A printhead segment length 93 in a multi-segment printhead is typically 21mm. The width of the printhead segment is typically 80 μm for solder joints 94 and other logic circuits, and 116 μm (95) for each color contained in the printhead segment (an additional fixer color channel is required in high-speed printing ). Table 1 lists the printhead segment widths for the most commonly used printhead types.
