Xerox Disclosure Journal
A single four-color printhead 10 that utilizes present fabrication techniques is shown in Figure 1 in cross-sectional view. Figure 2 is a cross-sectional view taken along line 2-2 of Figure 1. The printhead uses batch processing and simultaneous aligning and bonding techniques disclosed in U.S. Patent 4,601,777. Such a processing technique provides precise relative alignment of all four printheads and makes a precision alignment fixture on the printer unnecessary. The printhead is very small and light, especially if off-carriage ink supplies are used.
